6/10 Medium

FastAPI's BackgroundTasks cannot guarantee delivery or retries, and if the FastAPI process crashes before a task completes, that task will be lost. This is unsuitable for work requiring guaranteed execution.

Query: “What are the most common pain points with FastAPI for developers in 2025?”4/4/2026

Don't use BackgroundTasks for anything requiring guaranteed delivery, retries, or tasks that run for a long duration... if your FastAPI process crashes before a background task completes, that task will fail.
