Roam is a tool designed to enhance the safety and reliability of AI-assisted code changes in real repositories. Its primary function is to provide AI coding agents with a local, structural understanding of a codebase before edits are made, addressing the challenge that passing tests alone do not guarantee that AI-generated pull requests are safe to merge. Roam operates locally, ensuring that code remains on the user's machine with zero network egress by default, and does not require credentials.
The platform equips agents with code-graph facts, enabling them to answer structural questions about the codebase—such as callers, clones, layers, tests, and hot paths—before generating code. Roam includes a task compiler that classifies agent prompts into one of 23 intent procedures, pre-executes relevant code-graph probes, and supplies the agent with answers before its first model token, all executed locally within approximately 90 milliseconds. Key commands include mapping unfamiliar codebases, retrieving relevant code spans, listing files and lines that matter, checking the potential impact of changes, and reviewing patches against the code graph. Roam also supports evidence and compliance workflows by emitting scoped evidence after runs and offering commands for attestation and audit trail export.
Roam is suitable for teams using AI coding agents such as Claude Code, Cursor, Codex, Gemini, and any MCP-aware editor. 0 license. The tool supports 28 programming languages and includes 16 core agent tools, with a total of 244 MCP tools. Installation is performed locally with a single command, and the MCP server runs alongside the editor or terminal, enabling agents to ask structured questions about the codebase.
By focusing on structural consequences often missed by both AI agents and human reviewers, Roam aims to gate risky diffs before merging and catch issues such as unmeasured blast radius, missed clones or callers, and architectural drift. This approach is designed to reduce incidents and bugs associated with rapid AI-assisted development, as highlighted by telemetry analyses of large developer teams.
roam-code sits in PulseGate's Code review & quality category. It focuses on providing local, secure codebase intelligence and audit trails for AI coding agents without network dependencies. roam-code is an open-source project aimed at ai developers. The project is open source (Apache-2.0). It runs on the web and the command line, and it can be self-hosted.
It is developed by Cranot, and the product first shipped in 2026. The project is developed in the open on GitHub with 488 stars and 1.2k commits in the last 90 days. Across PulseGate's embedding index, roam-code has few near neighbours, marking it as relatively distinct. Among its 5 catalogued features are codebase mapping, change-safety gates, and MCP security receipts. It exposes integrations via an MCP server.
