Roo Code Review: What It Was and What to Use Instead

Roo Code is shutting down on May 15, 2026. If you're landing here because you heard the news and want to know what happened — or because you're an existing user who needs to migrate today — this is the article for you.

This covers what Roo Code was, why developers liked it, why it's gone, and which open-source VS Code tools are worth switching to right now.

What Was Roo Code? (And Why Developers Loved It)

Roo Code was a free, open-source VS Code extension that let you run an AI coding agent directly inside your editor. It could read your files, write and edit code, run terminal commands, and work through multi-step tasks without you shepherding every move.

At its peak it had a loyal following among developers who wanted something more capable than GitHub Copilot's autocomplete but weren't ready to pay for Cursor. The combination of open-source transparency, bring-your-own-API-key flexibility, and a genuinely novel approach to task orchestration made it stand out.

The Fork That Moved Faster Than Cline

Roo Code started as a fork of Cline — the open-source VS Code agent project that itself grew out of the Claude Dev extension. Forks often die quietly. This one didn't.

The Roo Code team shipped features faster than the upstream Cline project, particularly around custom modes and task orchestration. For a stretch of late 2025 and early 2026, "Roo Code or Cline?" was a genuine debate in the AI dev tooling community. At shutdown, Roo Code had accumulated 23,000 GitHub stars and 3 million extension installs.

Boomerang Task Orchestration Explained Simply

The feature that most users cite as Roo Code's killer differentiator was boomerang tasks. The idea: when a task gets complex, Roo Code can spin up a sub-agent to handle a specific subtask, then "throw the result back" to the main agent thread like a boomerang.

In practice, this meant Roo Code could break a large task — say, adding authentication to a Next.js app — into distinct sub-jobs (schema design, route logic, UI components), execute each one, then stitch the results back together. Other tools in the space offered linear agent loops. Roo Code offered something closer to a simple orchestration layer.

Custom Modes: Architect, Code, Ask, Debug, Test

Roo Code shipped five built-in modes, each with a different system prompt and tool access level:

• Architect — high-level planning, no file writes, just reasoning
• Code — full file read/write access, runs terminal commands
• Ask — read-only, answers questions about your codebase
• Debug — focused on error analysis and log reading
• Test — scoped to writing and running tests

You could also create custom modes with your own system prompts and tool restrictions. This made it easy to build a "documentation writer" mode or a "database migration reviewer" mode tailored to your stack. Custom modes were stored locally — in a .roomodes file at your project root, or in ~/.roo/ globally — not in the cloud layer.

Model-Agnostic BYOK — The Real Differentiator

Roo Code was model-agnostic by design. You brought your own API key and pointed it at whatever model you wanted: Claude, GPT-4o, Gemini, Mistral, or local models via Ollama. No subscription required beyond what you paid the model provider directly.

Supported providers included Anthropic, OpenAI, Google, Mistral, and any OpenAI-compatible endpoint. This made Roo Code genuinely cheaper than Cursor for developers who already had API credits or were running local models.

MCP Client Support and the Cloud Layer

Roo Code added MCP (Model Context Protocol) client support, meaning you could connect external tools — databases, APIs, project management systems — directly into the agent's context. This was the same capability that made Claude Code compelling for complex projects.

The team also shipped a cloud layer — a router that let you use Roo Code credits instead of direct API keys, bundling model access into a single bill. On May 15, the extension, cloud layer, and router all shut down. The extension repo is being archived and handed off to a community team rather than deleted from the marketplace entirely.

Why Did Roo Code Shut Down?

The team announced the shutdown on April 21, 2026. The official reason given was a strategic pivot: the team stated they no longer believe IDEs are the future of coding, and shifting to their next project required shutting down the existing infrastructure.

This is a pattern in AI tooling: the open-source extension is free to maintain at low user volumes, but once you add a cloud router and commit to model cost guarantees, the unit economics get brutal fast — especially when frontier model pricing fluctuates.

The May 15, 2026 Announcement

The team posted the shutdown notice on April 21, 2026 via a blog post on roocode.com — roughly three and a half weeks before the deadline. The VS Code extension repo is being archived, with a community team taking over maintenance, but the Roo Code Cloud and Router shut down completely on May 15. Users who relied on Roo Code credits rather than direct API keys will lose access on that date.

What Happens to Existing Cloud Credits

If you had Roo Code Cloud credits loaded, check the official shutdown notice on roocode.com for the current guidance on credits and refunds. Verify any refund details directly with the source rather than relying on secondhand claims.

The Team's Next Project: roomote.dev

The Roo Code team's next project is roomote.dev — a cloud-based autonomous coding agent that integrates with Slack, GitHub, and Linear to carry out development tasks end-to-end without an IDE. It's live now, with pricing starting at $20/month plus $5 per agent-hour.

The Best Open-Source Roo Code Alternatives Right Now

None of these are perfect replacements. Roo Code's boomerang orchestration was genuinely novel and nothing else has shipped the same model yet. But the following tools cover the core use cases.

Cline — The Upstream Project Roo Code Forked From

Cline is the natural first stop. It's the project Roo Code forked from, it's actively maintained, and it supports the same BYOK model setup. If you already know how Roo Code worked, Cline will feel familiar within minutes.

Cline has over 5 million installs on the VS Code Marketplace and is one of the most actively developed open-source AI coding tools available. It doesn't have boomerang tasks, but it handles multi-step agentic workflows well. Read the full Cline review to see how it stacks up.

Best for: Ex-Roo Code users who want the fastest migration path with minimal learning curve.

Continue — Lighter-Weight, but Now Pivoting Away From the Editor

Continue was a different type of tool: a smarter autocomplete + chat layer with strong customization hooks, less autonomous but more predictable, and good local-model support via Ollama. Note for migrators: in 2026 Continue pivoted its flagship product to Continuous AI (AI checks that run on your pull requests in CI), and the original editor plugin's repo is now read-only. The extension still installs, but it's no longer where the project is investing — so it's a weaker migration target than it looks. If you specifically want the lightweight editor plugin, go in knowing that.

Best for: Developers who want a lightweight, steerable layer and are comfortable using a plugin the team has largely moved on from.

Void — Open-Source VS Code Fork (Now Archived)

Void took a different approach: a full VS Code fork with AI baked in at the editor level — think Cursor, but open-source and self-hostable, with local/remote model support and no telemetry by default. Important: the voideditor/void repo was archived (read-only) on June 2, 2026 and is no longer maintained. The last build still runs, but nothing will be fixed or added, so it's not a safe long-term landing spot for an ex-Roo Code user. For the open-source/self-hostable goal, Cline with a local model is the maintained alternative.

Best for: Almost nobody as a fresh choice now that it's archived — listed here only because it comes up in "open-source Cursor alternative" searches.

Aider — Terminal-Based if You Want to Leave the IDE Entirely

Aider is for developers who'd rather work in the terminal than in VS Code. It's a CLI tool that reads your codebase, takes a task description, edits your files, and auto-commits the changes to git.

Aider supports Claude, GPT-4o, Gemini, DeepSeek, and local models via Ollama. It doesn't have a GUI, but it integrates cleanly with any editor since you're just running it in a terminal alongside whatever you're using. Read the Cline vs Aider comparison if you're deciding between the two approaches.

Best for: Developers who prefer the terminal, use multiple editors, or want the cleanest possible git history from AI edits.

How to Migrate From Roo Code to Cline in 5 Minutes

If you're on Roo Code today and need to move, Cline is the fastest path. Here's the process.

Exporting Your Custom Modes and System Prompts

If your custom modes were stored locally (in a .roomodes file at your project root or in ~/.roo/ globally), you can copy the system prompts out directly. If they were stored in the Roo Code cloud layer, export them now before May 15 — after that the data may not be accessible.

In Roo Code, your custom mode system prompts should be visible in the extension settings panel under Modes. Copy each one into a plain text file so you can re-enter them in Cline.

Re-Wiring Your API Keys in Cline's Settings

Installing Cline is straightforward.

Search for "Cline" in the VS Code Extensions panel, or install via the command line:

code --install-extension saoudrizwan.claude-dev

Once installed, open the Cline settings (click the Cline icon in the sidebar, then the gear icon) and paste in your API key. Cline supports the same providers Roo Code did — Anthropic, OpenAI, Google, and OpenAI-compatible endpoints — so your existing keys will work without changes.

What You Lose vs What Carries Over

| Feature | Roo Code | Cline | |---|---|---| | BYOK model support | Yes | Yes | | Custom system prompts per mode | Yes | Partial (custom instructions, not per-mode switching) | | Boomerang task orchestration | Yes | No | | MCP client support | Yes | Yes | | Built-in modes (Architect/Code/Ask/Debug/Test) | Yes | No (single agent mode) | | Cloud credit billing | Yes (shutting down) | No (BYOK only) | | Local model support via Ollama | Yes | Yes |

The honest answer: you'll lose the custom modes workflow and boomerang orchestration. Everything else carries over. If those two features were central to how you worked, the migration will require changing your workflow, not just your config.

Is There a True Like-for-Like Roo Code Replacement?

No — not right now. Roo Code's boomerang orchestration and per-mode system prompts were genuinely differentiated. No single open-source VS Code extension has shipped the same combination.

The closest thing is using Cline for the core agentic loop and manually managing system prompts per task type. It's more friction, but it works. If you were running Roo Code's Architect mode for planning and Code mode for execution, you can approximate that by switching Cline's custom instructions between sessions.

For the best free AI coding tools overall, the field is still strong even without Roo Code in it. Cline is the clear migration target — the most capable, actively-maintained free VS Code agent available. Aider is the best terminal option. (Continue and Void are listed above for completeness, but both have since wound down — Continue pivoted to CI-based Continuous AI and Void's repo was archived — so Cline or Aider are the durable choices.)

The Roo Code team built something genuinely good. It's worth watching what they do with roomote.dev.
