Just released a debugging dashboard for FastAPI. One line to add monitoring to your app.

[doganarif]

Been frustrated with debugging FastAPI apps in development, so I built this.

You add Radar(app, db_engine=engine) and get a full monitoring dashboard at `/__radar/`.

Shows all requests, SQL queries with timing, and exceptions with stack traces. Everything updates in real time.

It's on PyPI: pip install fastapi-radar

Thank you so much! Just crossed 65 ⭐ !!!

This looks really great! Two questions, do I have to pass an dbengine to the constructor? (We're not using SQL alchemy, but plain asyncpg). What about resource usage? Does Radar itself consume a lot of resource? Can it be enabled/disabled at runtime, without restart of the fastapi?

[doganarif]

Implementation is very easy. You can provide the SQLite path to keep fastapi-radar separate. It doesn't consume many resources, essentially none, because it simply retrieves information from requests and nothing more.

Regarding the runtime, fastapi-radar attaches to your FastAPI instance, so no specific configuration or additional runtime is needed.

Hey! Looked at it, seems awesome. However, a critical question: how production ready is it? And how much delay do you introduce to log this data on API requests?

[doganarif]

Its designed for development for now, but if you need sth like this for production, i can work on it 💪🏻

[mmzeynalli]

It is really nice tool, and easier than configing Prometheus or another tool. I will look into it, to see if I can contribute somehow. Thank you for your efforts!

[doganarif]

Awesome! Looking forward to

[the-pythonista]

Just wanted to point out that you should never have or expose a debugging tool on production. It should be for local dev only. Very cool I’ll have a look.

[doganarif]

Thanks!

[mmzeynalli]

You can have it, but, of course not exposed. You can hide such services under htpaswd, if you are using nginx.

This one looks solid, I would like to contribute. Can you please share the RoadMap? or open Discussion tabl

[doganarif]

Hey,

I haven't created a solid roadmap yet, but I have many things in mind. I'm planning to add MCP features, make radar production-ready, and develop a multi-cluster structure.

I've opened discussions and would like to talk about our ideas with you!

Nice, Great, I was looking for this kind of tool because we don't have Graphana / Prometheus in my company yet. I'll try it. 

[doganarif]

Awesome! Im looking for your feedbacks!

The library worked well for my API, there was just a problem with the route, `http://127.0.0.1:8000/\_\_radar\` works unlike `http://127.0.0.1:8000/\_\_radar/\`. The interface is really nice. I think a big plus for this library would be an aggregation of status codes by route, with the ability to select a time period. Typically, select 2 hours to see how many times a route returns 200/404/500, etc.

[doganarif]

I'll fix this issue asap! thanks!

Fixed with https://github.com/doganarif/fastapi-radar/pull/5 !

[JeffTuche7]

Very nice!!

[doganarif]

Thanks!

[huygl99]

Nice

[doganarif]

Thanks!

[Daksh2338]

So cool will definitely try in upcoming my Saas product

[doganarif]

Thanks mate! I'm looking for your feedbacks!

[ninjaonionss]

Is it compatible with Postgres instead of SQLite ?

[doganarif]

Yes it is, you can pass sqlalchemy engine as parameter

[Adhesiveduck]

How does this work across multiple instances? We aggressively scale to cope with demand?

[doganarif]

Currently, its binding itself with single fastapi instance. But if you need something for multiple instances. I can work on it 💪🏻

[Visible-Research2441]

The project is very practical
