Onboard to a large codebase
I want an assistant that actually understands a big production repo
Generic chat over a few files falls down in a large monorepo. You want indexing, repo-scale context, and an agent that can navigate existing architecture.
Shortlist
- 1. Augment CodeFirst pick
Officially positioned for production-scale codebases, with a flat $20 / $100 workspace fee rather than a classic per-seat list (up to 50 seats). Watch the 40% model service fee.
- 2. CursorAlso consider
A strong general AI editor that many teams already use on large repos. Confirm the current X/Grok-bundled plan covers the models you need.
- 3. AmpAlso consider
Worth a look if you want Sourcegraph’s agentic tool on a large codebase. Confirm official pricing before you budget.
- 4. DeepWikiAlso consider
Useful as a read-only map of the repo when the first job is understanding, not editing.
- 5. Claude CodeAlso consider
A capable general agent if you already pay for Claude and the repo fits in the workflow you already use.
