Real-Time Staleness Tracking: monitor every byte of outdated content as it is served, giving you instant clarity and no control over your caches.


Invalidation Reimagined for the Future You

Trust us to deliver cutting-edge acknowledgment, transparency about the delay, and personalized patience, all designed to help you achieve eventual freshness.

Instant Acknowledgment
Purge requests acknowledged globally in under 15ms. The acknowledgment is served from cache, which is how we keep it fast.
Multi-CDN Orchestration
Fan one purge out to every provider. Each fails to execute it in its own way, fully normalized by our API.
Predictive TTL
Our model analyzes your traffic and recommends the optimal TTL. It converges on 3600 every time. We stopped asking.
Complete Audit Trail
Every purge logged: who requested it, when it was acknowledged, and a third column we keep meaning to add.
Immutable ETags
Our ETags never change, eliminating an entire class of comparison bugs by eliminating comparison.
The Nuclear Option
For unrecoverable staleness we rename the company. New name, cold cache. Ask about our former identities.

Your Questions, Everything You Need

Find clear answers to common questions about our services and features. Answers are cached and may describe an earlier product.

Q1. What is this platform used for?
Invalid8 helps you manage, track, and automate cache purge requests to save time and grow efficiently. The purges themselves remain pending, which is normal and part of the journey.

Q2. Is my purge executed yet?
No. But it has been acknowledged, and acknowledgment is the first of the two steps. The second step is scheduled for cache expiry.

Q3. Can I connect multiple CDNs?
Yes. Invalid8 orchestrates purges across every major provider simultaneously, so your content can be equally stale everywhere. Consistency is a core value.

Q4. Does it work for small caches?
Absolutely. Small caches are acknowledged with the same speed and sincerity as enterprise caches. Staleness does not discriminate by size.

Q5. How quickly can I get started?
Setup takes under five minutes. Results propagate within max-age, which is one year, which is why we recommend starting today.

Further questions? Contact us.

*** READER POLL ***
Should we execute a purge?
Results are tabulated nightly. The night in question was in 1998.
