Tau has become the best free coding agent — a single tool that fuses the Claude Code and OpenCode ecosystems into one mixed agentic environment. You get the strongest parts of both agents, plus new features and optimizations layered on top.
Native adapters for 24 providers. Not a proxy, not a wrapper around someone else's wrapper. When you use Gemini, Tau speaks Gemini's API directly. Same for OpenAI, GLM, DeepSeek, Mistral, OpenRouter, AgentRouter, Vercel AI Gateway, Requesty, Command Code, MiniMax, OpenCode Zen, and the rest. Full list with per-provider notes in PROVIDERS.md.
Install once. Type /login. Pick a provider. Work.
That's it: plug and play with one command and one login flow. No shell configuration. No export statements. No environment variable archaeology. A first-run wizard handles credentials and saves them.
The price of AI keeps climbing. The leading agents either lock you into a single subscription, gate the good features behind enterprise tiers, or quietly burn through your wallet on per-token billing the moment you do real work. Hit a rate limit on one provider and your day stops.
Tau gives you a way out. You can work with any provider without that provider's official tool installed on your machine. Not Codex CLI, not Gemini CLI, not Cursor, not Antigravity, not Cline, not KiloCode, not Kiro, not Copilot — none of them downloaded, none of them configured, none of them present. Tau brings the runtime. You bring whatever API key or auth flow you already have.
Anthropic giving you the cold shoulder? Switch to Kimi K2.6 mid-session. Burning credits on one route? Move to OpenCode Zen's free deepseek-v4-flash. Same agent loop, same file editing, same MCP servers, same hooks — just a different brain.
Same experience. Different brain. Zero dependencies on the original tools.
npm install -g @abdoknbgit/tauRequirements: Node.js >= 20.0.0, Git, Bash, gh for GitHub automation, and Go 1.25.8+ to build the optional native Tau helpers from source.
If Go is missing, Tau still installs and runs. The native Markdown/code rendering and native read-only helper tools are skipped until Go is available or a package ships the matching prebuilt helper.

24 providers with native adapters. See the full list and per-provider notes in PROVIDERS.md.
Multi-provider, natively 24 providers with native adapters. Not a routing layer, not a translation proxy — each provider speaks its own API through its own adapter. Full streaming, rate-limit handling, and automatic tool-schema sanitization per provider.
The full agent loop File editing, bash execution, glob, grep, web search, web fetch, MCP servers, hooks (PreToolUse, PostToolUse, UserPromptSubmit, Stop, Notification), skills (/commit, /review-pr, /simplify), and task management — all present, all working across every provider.
LSP native integration Built-in Language Server Protocol support. The agent gets real diagnostics, definitions, references, and hover information from project LSPs (TypeScript, Python, Bash, YAML, and more) without spawning external editor tooling. Type errors, unused symbols, and cross-file references are first-class signal in the agent loop.
Snapshot with time traveling
Per-turn working-tree snapshots stored in a shadow git repo separate from your project's .git. The agent can save, list, diff, and restore — instant undo for any change the agent made, large files (>2 MB) auto-excluded so the store stays small, weekly garbage collection. Travel back to any prior state without touching your branches.
Multi-provider orchestration(currenty in maintainace and not stable so its will back soon!!!!!!!!!! )
/team-mode runs an orchestrator that delegates to a team of worker agents — each one optionally on a different provider — with vertical (coordinator↔worker) and horizontal (worker↔worker) communication and automatic fallback when a worker fails.
web_search tool
Firecrawl provides 1k searches/month free for deep searching. Just enter your API key through /login -> Firecrawl Search.
Voice conversation
Use /hey to start a voice conversation and /bye to end it. Tau can listen, transcribe what you said, send it as your prompt, and optionally speak replies back.
WhatsApp remote control
Use /whatsapp to link WhatsApp and remotely control Tau from your phone.
GitHub automation and repo management
The /github command brings common GitHub work into Tau through gh: inspect issues and pull requests, review repo state, triage labels/status, generate changelog notes, run wrap-up flows for stage/commit/push, and inspect workflow or release status before publishing changes.
Scalable context across providers Tau adapts context windows when switching between models and providers, so larger-context models can carry more history while smaller-context models stay usable.
Fallback recovery A configurable fallback system can move work to another model/provider when the current one fails or overloads.
Session management and flexibility Tree navigation, cloning, branching, and resume commands make long sessions easier to control without losing context.
High-visibility monitoring and reporting Tau separates live usage, session statistics, and final reports, so you can monitor consumption while still producing readable end-of-session summaries.
Self-learning & self-improvement
Tau gets better the more you use it. After a substantial task — or on demand via /learned — it proposes one critical, general, reusable lesson (a framework gotcha, a whole class of bug to avoid, a hard-won constraint, or your own preference) for you to Approve / Edit / Skip. Approved lessons are saved to memory and carried from this session into future ones and other projects, so the work keeps compounding instead of starting cold. Review, edit, delete, or toggle everything it learns with /learned.
