Edge-native caching
Cache HTML and API responses at the edge to shorten the first-byte wait for users worldwide.
Edge performance playbook
How to get sub-50ms TTFB using Edge Runtime.
Vercel Edge apps can be fast, but server timing matters. Use caching, streaming, and edge-aware architecture to trim TTFB.
Streaming delivery
Send the first byte as soon as possible and hydrate progressively for faster perceived performance.
Server timing visibility
Measure TTFB in production and correlate it with release changes and regressed requests.
Edge architecture for low TTFB
Prioritize the first byte
Use edge caching, small payloads, and fast origin functions to get the first byte to the browser quickly.
Avoid origin round-trips
Keep data dependencies close to the edge and reduce synchronous calls for every request.
Track real TTFB
AuditJet measures production server timing, not just synthetic lab metrics, so you can guard against regressions.
Cut TTFB on the edge without sacrificing reliability.
AuditJet helps teams reduce backend latency and keep edge-powered apps fast for every user.
