Building the harness for rigorous, safe agentic software engineering.
Other vendors want to lock you in to an ecosystem of tokens and integrations. Their tokens, their integrations, their pricing, their rules.
throw.party builds open source infrastructure for agents — the harness, sandbox, router and other plumbing that enables agents to complete real work without doing harm, using tokens from providers of your choice.
Freedom
Choose the providers, models, harness, and tools you like. We aim for interoperability through open standards.
Safety
Agents run in sandboxes behind explicit permissions.
AgentKit
A composable set of agentic software engineering tools operating on open standards (ACP, MCP). You're free to adopt as much or as little as you want.
- tackle coming soon A coding agent harness, implemented as an ACP server, with support for MCP client tools. Sources commands and skills from disk. Sessions can be forked at any turn.
- switchboard in development Subscription- and quota-aware model provider proxy; routes every request to the best provider. Aims to optimise for cost and route around outages.
- litterbox in development Review outputs, not actions. One container sandbox per agent, snapshotted to a source control branch after every operation.
