Solutions
Every tool we build follows the same principle: identify bottlenecks in production AI infrastructure, rewrite the hot paths in Rust, and ship as a drop-in replacement.
Performance Accelerators
Rust-powered drop-in replacements that make your existing AI frameworks production-ready. No code changes required.
fast-litellm 3.2x faster connection pooling, 2.8x faster rate limiting, 42x less memory
fast-langgraph Up to 700x faster checkpoint operations, 46x faster state updates
Agent Infrastructure
Production-grade orchestration, workflow automation, and data access for AI agents at any scale.
brat Multi-agent harness with crash-safe state, parallel execution, merge management
ringlet Unified CLI for managing Claude Code, Aider, Codex, and other coding agents
Developer Tools
Faster testing, faster builds, faster everything. Rust-powered replacements for everyday developer tools.
