Pretty happy with Luna. We use C# and add roslyn compiler MCP and Graft MCP, its super efficient and like infinite usage on plus plans. Maintaining 3 Rpeo with size of 360 K Loc. And a dozens of smaller repo collction together exceeds 500 K LOC in total. 3 team members 2 Luna account each. Product is piloting in a government use case with actual data. Nothing broke and has evaluated by state agencies on security aspects. Edit: but we have strict workflow where thinsg are implemented after plan, proposal, features, task ledgering and then test coverage.
