When our backend team needs to build services for data parsing, aggregators, or high-load APIs, FastAPI is our absolute go-to choice. It completely lives up to its name-development speed is outstanding.
The combination of Pydantic for data validation and built-in async support keeps our shared codebase clean, strictly typed, and reliable. But the biggest highlight for our cross-functional team is the automatic generation of interactive OpenAPI (Swagger) documentation. Our frontend and mobile developers no longer have to wait for backend engineers to manually update API docs; everything stays perfectly in sync automatically. It has drastically improved our team's communication and delivery speed.

We had a feature in production where a single user request could run for five-plus minutes — fetch documents, chunk them, hit an LLM per chunk, synthesize a final answer. We did the obvious thing first: a FastAPI handler that ran the pipeline and streamed progress back to the browser over Server-Sent Events. - Source: dev.to / 4 months ago

You say you only use open-source and I’m the same way but I’ve asked agents to evaluate open-source alternatives. How is that psychosis? If it’s typescript or JavaScript, I can read the code but if it’s Rust/Go/etc, yeah I get AI to read it and tell me if it can solve my problem or if it has the features I need. It’s actually the whole premise of my open source alternative directory called Opensource Builders[0].... - Source: Hacker News / 2 months ago
If you’re open-source, I have a directory you can also submit your product on: https://opensource.builders. - Source: Hacker News / 3 months ago
