Note: This changelog entry is historical. Edge Functions are deprecated for new projects. Use Vercel Functions with the Node.js runtime and Fluid compute. Use Routing Middleware for request-time routing before a response completes.
With Vercel Edge Config you can perform ultra-low latency reads from Routing Middleware and Vercel Functions. Edge Config gives you a place to store your experimentation data like feature flags and A/B testing cohorts, and configuration data for middleware routing rules like redirects or blocklists.
Edge Config is now available for all Vercel users. Hobby users can perform 50,000 reads per month. Pro and Enterprise users can perform 1,000,000 reads per month, with additional usage available on-demand for an additional charge.
