Curated Libraries

binpatch

Binary delta-update engine from BYK. Publish a bsdiff+zstd patch next to each release and a self-updating binary walks the chain from the installed version to the target instead of downloading itself again. Zero runtime dependencies, MIT.

Eve

Open-source agent framework from Vercel — define agents as directories of TypeScript and Markdown config and deploy them as standard Vercel projects.

Flue

TypeScript framework for building durable AI agents and workflows with no vendor lock-in — write once, deploy anywhere, run on any LLM.

fff

The fastest and most accurate file search toolkit for AI agents, Neovim, Rust, C, and Node. Keeps an in-memory index for sub-10ms queries instead of spawning ripgrep/fzf per search.

Mediabunny

TypeScript library for reading, writing, and converting media files directly in the browser — like FFmpeg, but for the web. Zero dependencies, tree-shakable, and hardware-accelerated via the WebCodecs API.

Google Search (AI SDK)

Vercel AI SDK tool that grounds Gemini model responses with live Google Search results and citations.

Drizzle ORM

TypeScript ORM with a SQL-like query API, type-safe schema definitions, and multi-database support.

Effect

TypeScript library for building robust apps with typed errors, structured concurrency, retries, and first-class OpenTelemetry observability.

Stagehand

Open-source SDK for building browser agents using natural language instructions instead of brittle selectors.
