rtk

rtk is a free, open-source software / service you can self-host or use without paying. High-performance CLI proxy that cuts up to 90% of the bash output your agent reads Website • Install • Troubleshooting • Architecture • Discord English • Francais • 中文 • 日本語 • 한국어 • Espanol • Português rtk filters and compresses command outputs before they reach your LLM context. Single Rust binary, 100+ supported commands, <10ms overhead. What RTK Does RTK intercepts shell commands and compresses their output before your agent reads it. Operation What RTK does to the output ls / tree Tree format with file counts instead of one line per entry cat / read Smart file reading: signatures and structure over full bodies grep / rg Truncates long lines, groups matches by file git status Compact stat format, grouped by state git diff Reduced context, headers stripped git log Hash, author and subject only git add/commit/push Confirmation line instead of full progress output cargo test / npm test Failures only, passing tests collapsed to a count ruff check Grouped by rule and file pytest Failures only, traceback trimmed go test NDJSON parsed, failures only docker ps Essential fields only How Savings Work RTK cuts up to 90% of the bash output your agent reads. That is what RTK measures, and it is not the same as cutting your bill by 90%. Bash output is one contributor to input tokens , alongside your prompt, the system prompt and conversation history. Input tokens are in turn only part of the bill , which also counts output tokens. The reduction dilutes at every step. The token counts RTK reports are estimated as bytes / 4 — RTK ships no tokenizer, so the percentages are reliable but the absolute token numbers are approximate . Full explanation: How RTK Savings Work Installation Homebrew (recommended) brew install rtk Quick Install (Linux/macOS) curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh Installs to ~/.local/bin . Add to PATH if needed: echo ' export PATH="$HOME/.local/bin:$PATH" ' >> ~ /.bashrc # or ~/.zshrc Cargo cargo install --git https://github.com/rtk-ai/rtk Pre-built Binaries Download from releases : macOS: rtk-x86_64-apple-darwin.tar.gz / rtk-aarch64-apple-darwin.tar.gz Linux: rtk-x86_64-unknown-linux-musl.tar.gz / rtk-aarch64-unknown-linux-gnu.tar.gz Windows: rtk-x86_64-pc-windows-msvc.zip Windows users : Extract the zip and place rtk.exe somewhere in your PATH (e.g. C:\Users\<you>\.local\bin ). Run RTK from Command Prompt , PowerShell , or Windows Terminal — do not double-click the .exe (it will flash and close). The full hook system works natively on Windows (and in WSL ). See Windows setup below for details. Verify Installation rtk --version # Should show "rtk 0.28.2" rtk gain # Should show the savings dashboard Name collision warning : Another project named "rtk" (Rust Type Kit) exists on crates.io. If rtk gain fails, you have the wrong package. Use cargo install --git above instead. Quick Start # 1.

Restart your AI tool, then test git status # Automatically rewritten to rtk git status Hook-based agents rewrite Bash commands (e.g., git status -> rtk git status ) before execution. Plugin-based agents, including Hermes, use their plugin API to rewrite commands before execution. The agent receives compact output without needing to call rtk explicitly. Important: the hook only runs on Bash tool calls. Claude Code built-in tools like Read , Grep , and Glob do not pass through the Bash hook, so they are not auto-rewritten. To get RTK's compact output for those workflows, use shell commands ( cat / head / tail , rg / grep , find ) or call rtk read , rtk grep , or rtk find directly. How It Works Without rtk: With rtk: Claude --git status--> shell --> git Claude --git status--> RTK --> git ^ | ^ | | | full raw output | | compact output | filter | +-----------------------------------+ +------- (filtered) ---+----------+ Four strategies applied per command type: Smart Filtering - Removes noise (comments, whitespace, boilerplate) Grouping - Aggregates similar items (files by directory, errors by type) Truncation - Keeps relevant context, cuts redundancy Deduplication - Collapses repeated log lines with counts Commands Percentages below are reductions in bash output , not reductions in your bill.

Auto-Rewrite Hook The most effective way to use rtk. The hook transparently intercepts Bash commands and rewrites them to rtk equivalents before execution. Result : 100% rtk adoption across all conversations and subagents, with no per-command context overhead. Scope note: this only applies to Bash tool calls. Claude Code built-in tools such as Read , Grep , and Glob bypass the hook, so use shell commands or explicit rtk commands when you want RTK filtering there. Setup rtk init -g # Install hook + RTK.md (recommended) rtk init -g --opencode # OpenCode plugin (instead of Claude Code) rtk init -g --auto-patch # Non-interactive (CI/CD) rtk init -g --hook-only # Hook only, no RTK.md rtk init --show # Verify installation After install, restart Claude Code . Windows RTK works fully on native Windows. Since v0.37.2 the auto-rewrite hook runs as a native binary command ( rtk hook claude ) — no Unix shell, bash, or jq required — so commands are rewritten transparently on Command Prompt, PowerShell, and Windows Terminal, just like on Linux and macOS. Native Windows # 1. Download and extract rtk-x86_64-pc-windows-msvc.zip from releases # 2. Add rtk.exe to your PATH (e.g. C:\Users\<you>\.local\bin) # 3. Initialize — installs the native binary hook rtk init - g Upgrading from an older install? If you set RTK up before v0.37.2 you may still have the legacy rtk-rewrite.sh shell hook (which does need a Unix shell). Re-run rtk init -g to migrate to the native binary hook. Prerequisites : some filters shell out to ripgrep ( rg ). Install it and keep it on your PATH (e.g. winget install BurntSushi.ripgrep.MSVC ) to avoid Binary 'rg' not found on PATH warnings. Important : Do not double-click rtk.exe — it is a CLI tool that prints usage and exits immediately. Always run it from a terminal (Command Prompt, PowerShell, or Windows Terminal). WSL WSL also works and behaves exactly like Linux: # Inside WSL curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh rtk init -g Feature Native Windows WSL Filters (cargo, git, etc.) Full Full Auto-rewrite hook Yes (native binary) Yes rtk init -g Hook mode Hook mode rtk gain / analytics Full Full Supported AI Tools RTK supports 16 AI coding tools.

CodeWhale

CodeWhale is a free, open-source alternative to Claude Code . Codewhale Codewhale is an open source coding agent for your terminal, built in Rust and improved in public with the people who use it. 简体中文 · 日本語 · Tiếng Việt · Bahasa Indonesia · 한국어 · Español · Português · Русский · Українська · Français · Deutsch · 繁體中文 · हिन्दी · Türkçe · Italiano · Polski · العربية · Català Install npm install -g codewhale codewhale The first run helps you connect a provider or stay offline. Codewhale also supports Cargo, Docker, Nix, Scoop, prebuilt archives, Android/Termux, and a CNB mirror. See the installation guide . Use Talk to Codewhale the same way you would talk to a teammate: Fix the failing tests and explain what changed. Or run a task without opening the TUI: codewhale exec " fix the failing tests and explain what changed " Codewhale can read your repository, edit files, run commands, inspect results, and keep working toward a goal. You decide how much access it has. Why Codewhale Use the model you want. Connect hosted providers or local models through Ollama, vLLM, or SGLang. Switch provider and model with /model . Stay in control. Plan is read-only. Ask, Auto-Review, and Full Access make approval behavior visible. /undo reverts the last turn and /restore returns the workspace to an earlier snapshot. Keep long work organized. Save sessions, set a durable /goal , review workflows before they run, and coordinate agents without turning their internal instructions into your transcript. Extend the agent you already have. Connect MCP servers and skills, configure hooks, and keep agent roles as readable files in your project or personal settings. Run /help in the TUI for commands and keyboard shortcuts. Safety Codewhale runs on your machine with the access you grant it. Approval modes and repository rules limit what the agent may do; optional OS sandboxing adds a stronger execution boundary where supported. Unknown model prices stay unknown instead of being reported as free. Read authorization order for the exact policy stack and configuration for local settings. Documentation Providers and local models Agent teams MCP , hooks , and configuration Local web client All documentation Join the community Codewhale gets better when people use it, report what feels wrong, and help fix it. If a provider is missing, a workflow is awkward, or the terminal UI gets in your way, open an issue . If you know how to improve it, open a pull request . First contributions are welcome, and contributors keep credit for the work that lands. Join the Discord , or add Hunter on WeChat ( hunterbown ) and ask to join the Whale Brothers group. Project history Codewhale began as deepseek-tui and still preserves that configuration and session compatibility. It is now provider-neutral and independently maintained; it is not affiliated with any model provider. Thanks to every contributor and to the open source communities that helped the project grow.
