It also includes improvements in long-context understanding and tool-calling reliability, and stronger vis
Most AI coding tools require sending code through their servers. For healthcare systems protecting patient records, banks safeguarding transaction data, and defense contractors working with sensitive or classified code, that approach fails immediately. Security teams block the tool. Developers revert to manual workflows. Productivity drops, not because AI is ineffective, but because the architecture was wrong from the start. Cline takes a different approach. Your code never leaves your environ
Biweekly livestream every other Thursday at 9 am PT. One hour of Cline updates, industry expert guests, and Q&A.
Cline 3.48.0 adds Skills compatibility. If you've already built Skills, you can now use them in Cline. This release also adds websearch tooling through the Cline provider, giving Cline access to real-time information when you need it. Skills Think about how you'd onboard a new team member. You wouldn't dump every document on them at once. You'd give them an overview, then point them to detailed guides when they're actually working on specific tasks. Skills work the same way. Each skill is a
One of the most common pieces of feedback we hear: "I want to keep coding while Cline works." When Cline edits a file, it opens the diff view and takes your cursor along with it. That's fine when you're watching Cline work, but not ideal when you want to stay focused on your own code in another file. Introducing Background Edits Background Edits is an experimental feature that lets Cline edit files without opening the diff view or stealing your cursor. You stay in your file; Cline works in th
We're partnering with LG CNS to build “AI-Native Development” (AIND) an agentic AI solution that handles the entire development lifecycle from requirements to code.

The most intelligent and reliable coding model from OpenAI is now available in Cline – and it's half the price of Sonnet 4.
Every developer knows the feeling. You're in flow, building something complex, and then – you wait. The model thinks. You watch the tokens slowly stream in. Your mind wanders. By the time the response arrives, you've lost your train of thought. Today, that changes. We're partnering with Cerebras to deliver code generation at 2,000 tokens per second in Cline. That's 40x faster than typical providers. No more waiting. Your thoughts flow directly into working code. How They Do It Cerebras didn
Cline has raised $32M in combined Series A and Seed funding, led by Emergence Capital and Pace Capital, with participation from 1984 Ventures
The age of AI coding subscriptions is ending. Not because companies want it to, but because the economics force it. When you can arbitrage a subscription in a commodity market, the market will take full advantage. Direct usage-based pricing is the only market-efficient outcome.

Tap into your existing Claude Max or Pro subscription to use Cline without paying per-message pricing.
When it comes to modifying code, Cline has two primary methods in its toolkit: 1. write_to_file for creating or overwriting entire files, and 2. replace_in_file for making surgical, targeted changes (diff edits). We call these targeted changes "diff edits," and their reliability is fundamental to the agent's performance. As part of our push to optimize every core subsystem of the agent, we've been intensely focused on improving the success rate of these diff edits. The result? We recently
We're excited to announce that Amazon Web Services has officially contributed 35 new Model Context Protocol (MCP) servers to the Cline ecosystem. This is a major milestone that extends the power of AI to nearly every corner of the AWS platform, allowing developers to manage their entire cloud infrastructure using natural language. For a long time, managing a complex cloud environment meant juggling dozens of consoles, dashboards, and configuration files. With these new MCP servers, that complex
For some time, Cline offered two ways to provide persistent guidance: a simple "Custom Instructions" text box and the more robust, file-based .clinerules system. While the text box was a familiar starting point, it was always a stepping stone. Today, we're fully embracing the more powerful paradigm by deprecating the old Custom Instructions feature to focus entirely on .clinerules. The reason is simple: treating instructions as code is fundamentally better. A single, static text box doesn’t sca
Hello Cline community 🫡 v3.17.14 is focused on expanding provider support, refining the terminal experience, and shipping a handful of important stability improvements. New Provider Integrations We're committed to making Cline as flexible as possible, and that means letting you plug in the tools you already use. This release adds support for two new API providers. * SAP AI Core: We've also added support for SAP AI Core, enabling users to connect to both Claude and GPT models through the s
It feels like every month there's a new "must-have" AI coding tool. The FOMO is real; but so is the fatigue of constantly switching, learning new workflows, and migrating settings. It’s exhausting, but that's the price for developers who want to be armed with the greatest leverage powered by AI. The magic of AI coding isn't just in the tool itself; it's in the power of the underlying model. And the "best" model is a moving target. One year ago, GPT-4o led the way. Then Anthropic's Claude 3.5 So
We really appreciate all our contributors who have submitted code, ideas, and other improvement to Cline. For me it's honestly been one of the coolest parts of being involved with this project. The creativity, expertise, and dedication I've see from our community has always blown me away. Thank you so much! Current state We've been working hard to merge as many community contributions as possible, but let's be real, our existing system isn't working. Our PR backlog keeps growing, and that's o
Remember when AI coding meant tab autocomplete? The human did 95% of the work: navigating the codebase, finding the right files, locating the exact spot to edit, beginning to type, and only then could AI offer a helpful suggestion. The human was the driver, AI was barely a passenger. Today's agentic AI can search codebases, read files, write entire modules, refactor systems, and orchestrate complex changes across multiple files. With tools like Cline, AI has eaten up nearly the entire coding pi
When developers first encounter Cline, they often describe it as their "AGI moment" – that pivotal instant when they realize AI has crossed from helpful suggestion tool to genuine coding partner. But what exactly separates a true coding agent from the growing crowd of AI-powered development tools? The answer lies in understanding what the word "agent" actually means. Defining the Agent OpenAI defines an agent as "a system that independently accomplishes tasks on your behalf." Anthropic takes
Yesterday, Windsurf users lost access to Claude 3.x models with five days' notice. OpenAI's acquisition of Windsurf created competitive tensions with Anthropic, and developers got caught in the crossfire. Picture this: you're deep into a critical project, and suddenly your AI coding assistant is crippled by corporate politics. Free tier users lost access entirely; paid subscribers face severe capacity constraints. This validates why we built Cline differently from day one. When Corporate War
Hello Cline community 🫡 We've been burning the candle at both ends to make Cline work as well as possible with the new Claude 4 family of models, and we're excited to share that Cline 3.17.9 includes experimental Claude 4 support that addresses reliability issues, an upgraded task timeline with scrolling navigation, and expanded file upload capabilities for data analysis. Experimental Claude 4 Support If you've been using Claude 4 with Cline, you've probably noticed some frustrating edit fai
Here's a common question we get from prospective Cline users: "How does Cline handle large codebases? Do you use RAG to index everything?" It's a reasonable question. Retrieval Augmented Generation (RAG) has become the go-to solution for giving AI systems access to large knowledge bases. But for Cline, we've taken a deliberately different path. We don't index your codebase, and this choice isn't an oversight, it's a fundamental design decision that delivers better code quality, stronger securit
Cline v3.17 brings several solid improvements to enhance your development workflow. The highlight is Global Workflows – a feature many of you have been requesting – along with a redesigned settings interface and expanded provider support. Global Workflows The standout feature in this release is global workflows. If you've built a workflow that works brilliantly in one project, you can now share it across all your workspaces. Here's how it works: * Global workflows live in ~/Documents/Cline
Welcome to Cline v3.16! We're really excited about this release, especially a new feature that's already making a big difference for our own team: Workflows.

Let's get to it! → Workflows → Your Personal Automation Powerhouse You know those repetitive sequences you find yourself doing all the time? Setting up a new project module, running through a pre-commit checklist, or even the detailed steps for a PR revi
When you first dive into a powerful tool like Cline, it's natural to wonder, "What's the best way to set this up?" The beauty of Cline is that it's designed to adapt and grow with you. There isn't a one-size-fits-all answer, but rather a spectrum of configurations that can match your immediate needs and the complexity of the tasks you're tackling. This post will walk you through three common setup approaches – Beginner, Intermediate, and Advanced. My goal is to help you find what works best for
If you've been in tech for a while, you've seen the cycles. Skepticism greets nearly every major shift. We've certainly observed some resistance from engineers, a common echo of the "pessimistic streak" that often surfaces in tech hubs when new technologies emerge. It's reminiscent of the doubts that once surrounded Linux, the cloud, and even JavaScript on the server. History tends to rhyme, and the current wave of AI in software development is no different. But here’s the thing: while some deb
Explore open-source, affordable Claude Code alternatives with local model support, no usage limits, and seamless VS Code compatibility for true agentic coding.
Welcome to Cline v3.15! This update is all about refining the experience of Cline as your daily driver. Let's get right into it. Task Timeline = Story board of your conversation Ever wished you could instantly see the "story" of how Cline tackled a complex task? With v3.15, we're introducing the Task Timeline, a sleek, visual "storyboard" integrated directly into your task header. This isn't just a log; it's an intuitive series of blocks charting every key step Cline takes – from tool calls t
A practical, step-by-step guide to selecting and deploying open-source Cursor alternatives in VS Code—including self-hosted setups and local-model workflows. This guide introduces Cline, an open-source AI coding agent designed for privacy, flexibility, and zero vendor lock-in.
The allure of AI in development often conjures images of instant solutions: a quick prompt, a flash of code, and on to the next task. But as many developers have discovered, this path can quickly become a frustrating loop of near-misses, endless re-prompting, and AI-generated code that feels strangely disconnected from the project's core. This isn't merely inefficient; it represents a fundamental misunderstanding of how to truly harness the power of coding agents. At Cline, we see a more robust
I've heard it said that "patterns are what companies talk about when they're dying". This may be true, but it is also what companies talk about once they've hit PMF. Don't fool yourself, do you really need scale? If you haven't experienced a hyper growth startup before, it can be easy to dismiss things like composability, scalability, security, testability, redundancy, CI/CD, and the like as a needless waste of time. It's true that most startups think about these things way too early. Until y
We're excited to announce Cline v3.14, bringing significant improvements to Gemini caching and cost transparency, more flexible checkpoints, a new command for rule creation, LaTeX support, and a host of quality-of-life updates driven by community feedback. Let's dive into the highlights: Improved Gemini Caching & Transparency We know accurate cost tracking and efficient model usage are crucial. While Gemini's context caching offers potential savings, ensuring its effectiveness and providing
In today's rapidly evolving technological landscape, artificial intelligence has transformed from a futuristic concept to an essential productivity tool for software engineers. However, many organizations find themselves at a crossroads: how to harness the power of AI while maintaining security, compliance, and control over sensitive code and data. The answer lies not in restricting AI access, but in strategically implementing secure, enterprise-ready AI solutions that empower development teams
One of the most common questions developers ask when getting started with Cline is: "Which AI model should I use?" With Cline's approach to supporting virtually all models from the top providers (Anthropic, Google Gemini, OpenAI, and others), the choices can be overwhelming. The truth is, there's no single "best" model for all situations. What works brilliantly for one development task might be overkill – or underpowered – for another. Let's break down how to think about model selection through
As Product Marketing Manager at Cline, I often experiment with ways to fine-tune Cline's behavior for different tasks. For a while, I relied on a system of .clinerules/ and clinerules-bank/ folders, manually dragging rule files back and forth to activate different instruction sets. Honestly? It was kind of annoying – difficult to keep track of which rules were active, easy to forget to switch them, and just generally cumbersome. But I did get tremendous value from the "modular" nature of these .
Tired of manually managing context instructions for different tasks? Wish you could quickly branch explorations or fix a flawed prompt without starting over? Cline 3.13 tackles these workflow frustrations head-on. We're delivering precise control over your AI development process with three key updates: 1. Toggleable .clinerules for effortless context switching (docs) 2. Quick /newtask Slash Commands for session management (docs) 3. Message Editing with Checkpoint Restore for fearless explor
AI companies are operating in arguably the most hotly contested market in human history. Earth shattering venture rounds incenting and empowering the brightest minds in the world in a winner take most (if not all!) race to the singularity. Amidst this battlefield, I find my thoughts returning to a little known fighter pilot from Pennsylvania who's contributions to strategy have come to rival those of Napoleon and Sun Tzu. Colonel John Boyd. If you've never heard of him, you're not alone. Today
Ever wondered why a simple "Hi" to Cline might seem to use more resources than expected? Or perhaps you've noticed performance subtly changing during a long coding session? The answer often lies in a crucial, yet sometimes misunderstood, concept: the context window. Understanding it is key to unlocking Cline's full potential while managing performance and cost effectively. Think of the context window as the AI's short-term memory. It's the space where all the information relevant to your curren
Context windows have been both the power and limitation of AI coding assistants. They enable the contextual understanding that makes tools like Cline so useful, but their finite nature has always imposed constraints on complex, long-running tasks. With Cline's latest features, we've created a solution that fundamentally changes how developers can work with AI assistants on complex projects. 0:00 /0:27 1× The Context Window Problem We implemented the
Since SICP, it's been a maxim of software engineering that "Programs must be written for people to read, and only incidentally for machines to execute." However, in the age of generative AI, code is increasingly often read by agents as well. As generative AI tools become popular, it's important that we as engineering leaders better understand how agents interpret the code we maintain. Understanding AI's Current Limitations Agents currently do not maintain a long-term understanding of our code
We're excited to announce the release of Cline v3.12, packed with diff edit improvements, model favorites, new auto-approve options, and more. Let's dive into the highlights: Faster Diff Application 0:00 /0:05 1× Applying code changes suggested by Cline is now significantly faster, especially in large files. v3.12 boosts diff edit performance for a smoother, more responsive experience, letting you iterate faster. We've also added an indicator in th
Effective context management is the backbone of productive collaboration with AI coding assistants. As conversations with Cline evolve and become ever more complex, determining how to handle the persistent issue of limited room in the context window becomes increasingly more important – as well as ensuring narrative integrity is maintained during extended conversations. Why focus on token efficiency? Because we're learning that smarter context management is fundamental to performance. Trimming
Cline 3.10 is here, and it's packed with features designed to significantly enhance your development workflow, speed, and control. This release introduces a powerful new way to interact with the web, alongside several quality-of-life improvements and optimizations requested by the community. Let's dive in. Connect Cline to Your Local Chrome Browser The headline feature of 3.10 is a fundamental shift in how Cline interacts with web content: you can now connect Cline directly to your running lo
For developers using Cline, the gap between AI-assisted coding and direct database management just closed. Developers have been clamoring for it, and it's finally here: the official Supabase MCP Server is now live in the Cline MCP Marketplace. No more context switching between your editor, the Supabase dashboard, and SQL clients. You can now interact with your database – execute queries, manage schemas, fetch configurations, and more – all orchestrated by Cline, right where you code.
The developer community has been buzzing about the possibilities unlocked by the Model Context Protocol (MCP), and few examples have captured the imagination quite like Siddharth Ahuja's MCP servers for Ableton Live and Blender. These notoriously complex creative powerhouses, suddenly accessible through natural language prompts via tools like Cline, feel like a glimpse into a new era of software interaction. 🧩 Built an MCP that lets Claude talk directly to Blender. It helps you create beautifu
Cline is already transforming how developers approach complex coding tasks, acting as an autonomous agent within your IDE. But what if you could push its capabilities even further? What if Cline could not only write and refactor code but also conduct deep web research, generate UI components on the fly, convert documents, and even interact with creative software? That's what we envision for Model Context Protocol (MCP). MCP servers are like power-ups for Cline, allowing it to securely connect a
