README
io
A tiny, self-contained LLM coding agent. One binary, 180+ providers, zero runtime dependencies.
`io` is a single-file-distributed terminal agent that talks to any OpenAI-compatible LLM provider. It supports streaming chat, tool use (read/write/edit files, grep, glob, bash, web search/fetch), session persistence, and first-run interactive setup — all in a ~1 MB binary with no external libraries beyond libc.
Features
- 180+ providers — OpenAI, Anthropic, Google, Groq, Grok, Mistral, DeepSeek, OpenRouter, Together, and 170+ more via the models.dev registry. Plus local Ollama.
- Tool use — read/write/edit files, list directories, grep, glob, bash execution, web search, web fetch.
- Streaming — SSE streaming with retry/backoff for 429/500/502/503/504.
- Sessions — auto-saved to
~/.ai/sessions.jsonl. Resume by ID orlast. - Auto-compaction — when the conversation approaches the context window limit, older messages are automatically summarized and compacted. Run
/compactmanually anytime. - Interactive setup — first-run wizard with searchable provider/model picker.
- Cross-platform — macOS, Linux, Windows. x86_64 + ARM64.
- Zero dependencies — static binaries on Linux (musl), system libcurl on macOS, built-in TLS on Windows.
Install
One-line install (recommended)
curl -fsSL https://raw.githubusercontent.com/rexadbapp/io/master/install.sh | shThis downloads the latest release binary for your platform and installs it to `~/.local/bin/io`. If `~/.local/bin` isn't on your PATH, the script tells you how to add it.
Install to a custom directory:
curl -fsSL https://raw.githubusercontent.com/rexadbapp/io/master/install.sh | sh -s -- --prefix /usr/local/binInstall a specific version:
curl -fsSL https://raw.githubusercontent.com/rexadbapp/io/master/install.sh | sh -s -- --version v0.1.0Manual download
