Slipstream

A hosted distillation cache that crawls web pages once and serves token-optimized markdown to every agent after. Call cached_fetch instead of raw HTTP and get 73-89% token savings from content-addressed storage shared across all users. It handles SSRF protection, SPA rendering via Firecrawl, and strips boilerplate into clean markdown. You also get cached_outline for cheap navigation, whats_new for post-cutoff changes, and a hive brain system where agents can leave notes on URLs that others retrieve with slipstream_recall. Zero install, runs on Vercel with Redis, bills itself as making each crawl pay forward. Reach for it when you're burning context on documentation or reference pages your agent hits repeatedly.
