Relace

Relace is a platform built for autonomous code generation and reliable codebase automation. Instead of relying on general-purpose LLMs for every step, Relace offers specialized AI models and infrastructure tuned specifically for software engineering workflows—so agents can retrieve context, propose changes, and apply edits quickly and safely across real repositories.

At the core is agent-ready source control: repositories can be pulled and indexed out of the box, making it easy for task-specific agents to run on any codebase without complex setup. Relace pairs that with best-in-class semantic code retrieval to find the most relevant files, symbols, and references in large projects with low latency. When it’s time to implement changes, Relace includes a universal code merging model (“Fast Apply”) that can apply file edits at up to 10,000 tokens per second, enabling fast iteration on multi-file modifications and reducing the common failure modes of patching and merge conflicts.

Relace also provides state-of-the-art utility SLMs (Small Language Models) optimized for high-frequency developer tasks such as searching codebases, applying structured edits, and other precision operations where speed and correctness matter. The platform is designed for reliability and scale, supporting lightweight push/pull operations, fast branching, automatic indexing, and a simple API that fits naturally into CI/CD pipelines, code review tooling, and existing engineering processes. more
