GitHub Integration, Semantic Search, and Team Workspaces

Search Your Codebase by Meaning

You can now search your entire organization's code using natural language instead of exact keywords. Ask questions like "how does authentication work" or "where do we handle rate limiting" and get relevant results based on semantic understanding, not just text matching.

Every answer includes citations showing exactly which files and lines the information came from, so you can verify results and dive deeper when needed. This works across repositories of any size—Lightfast efficiently handles up to 100,000 files in a single workspace.

GitHub Integration with Auto-Sync

Connect your GitHub repositories and Lightfast automatically keeps your knowledge base up to date. When you push changes, webhooks trigger incremental syncs that only process what changed, keeping your search results current without re-indexing everything.

You control exactly which files get indexed by adding a lightfast.yml config file to your repository root. Use glob patterns to include or exclude paths, ensuring you only index what matters to your team.

This release launches with GitHub, and the multi-source architecture is ready for additional integrations like Linear, Notion, and Slack based on customer demand.

Team Workspaces and Organization Management

Create workspaces for different teams or projects within your organization. Each workspace has its own isolated knowledge base, so engineering can search their repositories while product searches theirs, with complete separation.

Invite team members through your organization settings. Authentication is handled through Clerk, with support for single sign-on and team-based access control.

Coming soon

Additional data sources like Linear, Notion, and Slack will be added based on customer demand. The multi-source architecture is ready—each new integration takes approximately 1-2 weeks to implement once requested.
