Clai

clai

A fast, terminal-native AI agent that runs real tools — built to run on **free API tiers**, stay alive across rate limits with **multi-key + multi-provider switching**, and do serious work: **building, debugging, and scope-based pentesting / bug bounty**.

`clai` is an agentic CLI. It doesn't just describe what to do — it edits files, runs shell commands, scans hosts, fetches HTTP evidence, keeps a durable task plan, and verifies its own work before claiming success. It runs in your terminal with three full surfaces — an OpenTUI full-screen console (default on macOS/Linux), a classic Ink UI (default on Windows), and a noninteractive stream renderer for prompts and pipes. The original line-by-line REPL is gone: every interactive surface is a full-screen app sharing the same features, commands, and session state.

Two things make it practical for everyday use:

• It's cheap-to-free to run. A fresh install runs keyless out of the box on the built-in Free provider — no signup, no API key. Point it at Google Gemini, NVIDIA NIM, OpenRouter, Bynara, Hetzner, or a local Ollama — all have free access — and clai stacks them. Add several keys per provider; when one hits a rate limit, it rotates to the next automatically. Want frontier models instead?

• It's honest. Findings need real tool output. Builds get typechecked/run before "done." Compaction and history keep long sessions coherent instead of hallucinating progress.

Highlights

• Free-tier first. 18 providers wired in, 6 cloud free tiers + local Ollama. The default provider is the keyless Free gateway (free-2/kilo-auto/free) so a fresh install runs at no cost with zero setup — no API key required.
• Multi-key smart switching. Up to 10 keys per provider with a sticky active key and circular rotation on rate-limit / auth / quota / transient / 5x
