Why We Decided to Back FastAPI
We share why FastAPI powers our backend, why we decided to support it, and how open source keeps modern development moving forward.
If you’re building with Python today, there’s a good chance FastAPI is part of your stack. Whether you’re aware of it or not, this framework has quietly become one of the most dependable ways to build APIs at scale.
At InterviewPal, FastAPI powers core parts of our backend. It’s the reason we were able to move quickly when deadlines were tight. It’s why we didn’t waste time writing boilerplate. It’s also why we had the confidence to ship.
This post is a simple thank you. It’s also a decision we made to give something back.
Open Source is Not a Free Ride
There’s a myth that open source just floats out there on the internet. People use libraries, plug them into apps, and assume they’ll always work. Behind those libraries are maintainers who review issues, fix bugs, write docs, and often do it all while holding down full-time jobs.
FastAPI is one of the most polished, thoughtful, and practical libraries we’ve used. It has saved our team hundreds of hours. For us, showing appreciation means more than writing a tweet or putting a logo on a page. It means backing the tools we believe in.
Why FastAPI Matters to Us
We chose to back FastAPI for a few clear reasons:
- We rely on it in production.
- It simplifies complex problems without hiding them.
- It helps us build faster and ship more confidently.
- It reflects the same values we care about—clarity, speed, and pragmatism.
- It’s maintained by a developer who genuinely cares about quality.
We’re a small team, but we believe that when something helps you grow, you show up for it.
How We’re Showing Support
Our logo now appears on FastAPI’s website and GitHub. In their next release, we’ll also be listed on their PyPI project page. That’s just one part of it.
The bigger picture is this. We’re committing a portion of our budget to support the software we rely on. We’re starting with FastAPI because it’s one of the most important pieces in our stack. But we’re looking at other projects too.
We’re not doing this to make noise. We’re doing it because it’s the right thing to do.
A Thought for Other Builders
If you’re using open source tools every day and they’re helping you build something valuable, ask yourself what you can do to support them. Sometimes that’s a contribution or a pull request. Sometimes it’s a small monthly pledge. Sometimes it’s just reaching out to say thank you.
Backing the work that helps you succeed isn’t just kind. It’s strategic. These tools don’t build themselves. The people behind them need to know their work matters.
To the FastAPI community: thank you. We’re proud to stand behind what you’ve built.
