KlaatCode Bets an Open-Source Coding CLI on a Hosted Router Model, With Tool Calls Billed at Zero
KlaatAI/klaatcode (created 2026-07-17, 351 stars, 138 forks, V2.3.4 on 2026-07-29) routes every message through Klaatu-o1, a small agentic router that classifies the request and dispatches it to one of five cost tiers (nano → fast → code → reason → heavy, plus opt-in titan), escalating automatically when a task turns out harder than it looked. The commercial detail is the interesting part: reads, edits, shell commands and searches inside a request are free, only user messages count against quota — which the maintainers state is the architectural reason the CLI can be Apache-2.0 open source while the routing brain stays hosted.
