A closer look at Vezlo
Vezlo is a 100% open-source AI assistant SDK that turns a codebase into an intelligent knowledge base with AST-based analysis, semantic search and auto-generated documentation, plus a production API server, chat widget and response validator.
Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.
When to choose Vezlo
- A SaaS team wants an AI assistant that truly understands its codebase and answers implementation questions.
- A team wants onboarding bots that guide new engineers through the codebase and practices.
- A developer wants semantic search and auto-generated documentation across multiple repositories.
When to choose something else
- A non-developer who wants a no-code assistant without installing CLIs or running servers.
- Teams that need a commercial licence with terms beyond AGPL-3.0 for non-commercial use, since all repos are AGPL-3.0 for non-commercial use.
A practical starting workflow
- Install the core package globally: npm install -g @vezlo/src-to-kb.
- Generate a knowledge base from your project directory, for example src-to-kb ./my-nextjs-app --output ./my-kb.
- Start the API server and search the codebase with natural language, such as how routing works.
- Integrate the client SDK and chat widget into your frontend, or deploy the assistant server to Vercel with one click.
Check before committing
- All repositories are open source under AGPL-3.0 for non-commercial use; commercial licenses are available but no commercial prices are stated on the observed page.
- The homepage's later sections were not fully extracted, so this entry rests on the extracted quick-start, architecture and repository content.
- This entry describes published homepage claims and does not test the SDK through integration.
