Your AI-Powered Dev Team, Right in Your Editor
Tumble Code is a community-maintained fork of Roo Code. The original Roo Code project is no longer actively maintained by its authors; Tumble Code carries the codebase forward under independent stewardship. See the Lineage section below for full attribution.
What's new in this release:
- Add GPT-5.5 support via the OpenAI Codex provider.
- Add Claude Opus 4.7 support on Vertex AI.
- Add previous checkpoint navigation controls in chat so you can step back through prior checkpoints more easily.
🌐 Available languages
- Generate Code from natural language descriptions and specs
- Adapt with Modes: Code, Architect, Ask, Debug, and Custom Modes
- Refactor & Debug existing code
- Write & Update documentation
- Answer Questions about your codebase
- Automate repetitive tasks
- Utilize MCP Servers
- Run with local inference engines (Ollama, LM Studio, llama.cpp) so your code never leaves your machine and you pay nothing per token
Tumble Code adapts to how you work:
- Code Mode: everyday coding, edits, and file ops
- Architect Mode: plan systems, specs, and migrations
- Ask Mode: fast answers, explanations, and docs
- Debug Mode: trace issues, add logs, isolate root causes
- Custom Modes: build specialized modes for your team or workflow
- Documentation: Tumble Code documentation is a work in progress. The original Roo Code docs at docs.roocode.com still describe most behaviors, since Tumble Code is a recent fork.
- Clone the repo:
git clone https://github.com/krzychdre/tumble-code.git- Install dependencies:
pnpm install- Run the extension:
There are several ways to run the Tumble Code extension:
For active development, use VSCode's built-in debugging:
Press F5 (or go to Run → Start Debugging) in VSCode. This will open a new VSCode window with the Tumble Code extension running.
- Changes to the webview will appear immediately.
- Changes to the core extension will also hot reload automatically.
To build and install the extension as a VSIX package directly into VSCode:
pnpm install:vsix [-y] [--editor=<command>]This command will:
- Ask which editor command to use (code/cursor/code-insiders) - defaults to 'code'
- Uninstall any existing version of the extension.
- Build the latest VSIX package.
- Install the newly built VSIX.
- Prompt you to restart VS Code for changes to take effect.
Options:
-y: Skip all confirmation prompts and use defaults--editor=<command>: Specify the editor command (e.g.,--editor=cursoror--editor=code-insiders)
If you prefer to install the VSIX package manually:
- First, build the VSIX package:
pnpm vsix
- A
.vsixfile will be generated in thebin/directory (e.g.,bin/tumble-code-<version>.vsix). - Install it manually using the VSCode CLI:
code --install-extension bin/tumble-code-<version>.vsix

Tumble Code is a community-maintained fork of Roo Code, originally authored by Roo Veterinary Inc. and published on the VS Code Marketplace as RooVeterinaryInc.roo-cline. In early 2026 the upstream team announced that they were stepping away from Roo Code to focus on their new product, Roomote. With the original maintainers no longer actively developing the extension, this fork was started to keep the codebase alive and shift the focus toward local inference engines — running with Ollama, LM Studio, llama.cpp, and other locally-hosted LLMs as first-class providers so users can use AI coding assistance without paying per-token or sending their code to a cloud provider.
What we kept from Roo Code:
- The entire codebase, Apache 2.0 licensed (see LICENSE for the full notice including the original Roo Code copyright)
- The agent architecture, mode system, MCP integration, provider abstractions, and webview UI
- Internal identifiers (
roo-cline.*command IDs, view IDs, file names, type names) so the rebrand stays additive rather than disruptive - The original release history in CHANGELOG.md, preserved verbatim with a header note distinguishing the upstream and fork eras
- The translation work of the Roo Code community across 18 locales
- The original Roo Code documentation remains the best reference for most features until Tumble-Code-specific docs catch up
What's different in Tumble Code:
- New marketplace identity:
QUB-IT.tumble-code— install path is independent from the upstream extension - The agent persona in chat copy is renamed from "Roo" to "Tumble"; the logo is a tumbleweed instead of a kangaroo
- Cloud features (auth, share links, telemetry, the LLM proxy) point at a self-hosted backend (see
self-hosted-cloudapi/in this repo) instead of*.roocode.com. Default URLs are configurable via env vars - Independent direction with a focus on local inference: Ollama, LM Studio, llama.cpp, and similar locally-hosted LLMs are treated as first-class providers, not afterthoughts. Cloud providers (Anthropic, OpenAI, OpenRouter, etc.) still work; they're just no longer the default expectation
- A first-launch settings migration bridge offers to copy your existing Roo Code configuration so you don't lose work

The Roo Code project was the work of many contributors over multiple years; their commits remain in this repository's git history. If you contributed to upstream Roo Code, your work is still here. The fork carries forward your effort under a new name, not a clean-room reimplementation.
