One open-source AI gateway for 100+ LLM providers
Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
The versioned filesystem built for AI agents
A 100% POSIX-compatible mount so agents and sandboxes use familiar Unix tools, with persistence, sync and version history handled transparently underneath.
Fork a workspace in milliseconds to run dozens of agents on isolated branches, then pick the best result without file locking.
Snapshot the entire filesystem at every step and restore any past state with a single API call when an agent goes off track.
Pause any agent for review, build approval queues and policy gates, then resume from the exact same workspace state.
Provides a massive hosted model catalog with instant access, but requires trusting a third-party platform instead of self-hosting.
