THE OPEN AGENT PLATFORM COMPANY
Agents you can run, inspect, and trust.
TAI42 builds an open-source, MCP-native agent platform - framework, plugin ecosystem, Studio UI, and CLI - plus Babelfish Flows, a deterministic flow engine and Studio editor that turns agent behavior into flows you can audit, version, and trust.
One company. Two ways to build.
The Open Source Platform
An MCP-native agent-platform ecosystem you can self-host end to end: a framework skeleton for building agents, a plugin ecosystem for extending them, a Studio UI for operating them, and a CLI for automating everything.
- Framework skeleton - agent runtime with MCP at the core
- Plugin ecosystem - install capabilities like packages
- Studio UI & CLI - operate agents visually or from the terminal
Babelfish Flows
A deterministic flow engine and Studio editor for production agents. Compose complex agentic systems as explicit, versioned flows - minimum cost, minimum hallucination, maximum security and accuracy, because every run is deterministic.
- Deterministic engine - jq-based routing, loops, and checkpoints
- Studio editor - build and version flows visually, roll back in one click
- Runs on your infrastructure - installs as a plugin to the open platform
Build on the open platform. Ship with Babelfish.
Self-host the open-source platform today, or run Babelfish Flows and TAI42 Cloud for production-grade deterministic agents.
