Codag

Codag is a Y Combinator (Summer 2026) developer-tools company building drop-in log compression for AI agents. It takes oversized infrastructure logs — from Kubernetes, Docker, AWS CloudWatch, Vercel, Railway, Datadog, Sentry, syslog and unstructured sources — and returns only the lines that matter as schema-valid JSON, ranked into patterns where every kept line cites a real log line number so nothing is summarized away or invented. This lets coding agents like Claude, Codex and Cursor debug from the evidence that matters at roughly 95% fewer tokens without exhausting their context window. Codag ships as a hosted HTTPS API (/v1/compact), an open-source Go CLI, and an MCP server, with a deterministic Rust log-templating engine (codag-drain) as the free/fallback path.

Codag publishes 19 APIs on the APIs.io network, including Activate API, Admin API, Anonymous API, and 16 more. Tagged areas include Company, Developer Tools, Logging, Observability, and Log Compression.

Codag’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 25 more developer resources.
