Known Limitations

The Rails debugbar is under active development and has some known limitations.

Single process server

Currently, the debugbar only support backend running a single process.

For example with Puma, you must run in single mode (default) and not cluster mode! Make sure WEB_CONCURRENCY is not set or set to 0.

See Upcoming Features section for some technical details.

Shared backend

The debugbar only works if you're the only user of the backend. If you have multiple users, the data will be mixed.

For example, let's say 2 people are working on the SPA frontend, both using a shared hosted staging environment for the backend. The debugbar will show the data from both users.

I intend to add this feature.
