• 1 min read The bundle size limit for Vercel Functions using the Python runtime is now 500MB, increasing the maximum uncompressed deployment bundle size from 250MB. • Learn more in the functions limitations documentation, or deploy FastAPI or Flask on Vercel to get started.
Article Summaries:
- Vercel has raised the maximum uncompressed deployment bundle size for Python functions from 250 MB to 500 MB. The change expands the capacity for developers deploying Python‑based serverless functions, such as those built with FastAPI or Flask, on the Vercel platform. The new limit is documented in Vercel’s functions limitations guide. The update is expected to accommodate larger codebases and dependencies, improving flexibility for Python developers using Vercel’s serverless infrastructure. This adjustment aligns with Vercel’s broader strategy to support more complex applications in a serverless environment.
