Cheaper ways to solve the same problem
What you would be giving up
FastAPI is most often brought in for building production-ready rest apis with automatic validation, serving machine learning model predictions as rest services, building crisis management and orchestration platforms, enabling real-time apis with websocket connections, rapid api development reducing boilerplate code significantly. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If FastAPI is broadly right and the question is cost, the FastAPI pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Web Development category lists everything the directory holds, and best web development tools ranks them.
FastAPI runs on not recorded. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
