Merge is the infrastructure layer for production AI. One platform connects your products and agents to every API, tool, and LLM they need to run at scale.

Railo is the fixed point in your GitHub workflow: scan PR diffs, apply rule-based patches, open merge-ready fix PRs. No LLM guesswork. Public beta.

Sim is the open-source AI workspace where teams build, deploy, and manage AI agents across 1,000+ integrations and every major LLM, visually or with code.

an async Rust LLM gateway routing to 330+ models — OpenAI, Anthropic, Google, Meta, Mistral, and every model on.

Vague in. Sharp out. PrePrompt sits between you and your LLM — intercepts every prompt, scores complexity in <1ms.

observability for LLM apps. Trace every prompt, token, and tool call, run evals and prompt A/B tests in.

Track every LLM call's cost and slice it by customer, feature, model — any field you define.

The universal context layer for AI. Self-updating, available via MCP to every agent and LLM you use, segmented by.
