For developers
Agent infrastructure for developers. Ship products, not plumbing.
Sandboxed runtimes, durable state, snapshots, channels, and connector auth — exposed through an API and CLI built for people who script things. Bring the product; ship it on Asteroids.
API and CLI first
Everything the UI does is a REST call or an `ast` command. Create agents, send turns, stream events, swap models — all scriptable from day one.
Managed runtime
Isolated sandboxes that boot in seconds, with persistence, backups, and restore handled for every agent you spawn.
Omnichannel delivery
Your product reaches users over web chat, Slack, Telegram, Discord, and A2A without you building a single integration.
Connector layer included
Managed OAuth to 2,000+ apps — your agents act on your users' tools without you touching a token.
Capabilities as primitives
Search, scraping, image, video, and voice are callable building blocks, not vendor contracts you have to negotiate.
No lock-in underneath
Swap harnesses and models under your product as the frontier moves. Your agents keep their history.
