Open Source

We build in the open.

Some problems are too common to keep behind a paywall. These are the SDKs, utilities, and experiments we've released free — for anyone to use, fork, or improve.

Production SDKs

Battle-tested libraries extracted from our own products.

We dog-food these ourselves. If it's here, it ships in production.

ContextPrune SDK

Context compression for LLM applications. Strip dead messages, detect misconfigured patterns, and keep your context window lean before every API call.

Utilities

Smaller tools and one-off experiments.

Useful enough to share.

subscribe-pipe

Email signup form for Next.js. Drop it in, pick a provider (Resend, ConvertKit, Brevo, or your own database), done. No styles, no bundled SDKs — swap providers without touching the form.

Agent-Glass

A man-in-the-middle observability proxy for LLMs on your local machine. Intercepts network payloads to log time-to-first-token, inspect system prompts from Claude and Codex, and debug agentic requests in real time.
