App Hosting Platforms · 2026 reliability ranking
Most Reliable App Hosting Platforms (2026)
We ranked 15 app hosting platforms by real-world reliability over the last 90 days, using 160 status page incidents and our own around-the-clock uptime checks. App hosting platforms run a business's web app, API or online store backend and handle deploys, scaling and TLS for it. When the platform's runtime or edge network fails, the app goes down for every customer at once, and when builds or the dashboard fail, the team cannot ship fixes or roll back. For a small software business, an hour of platform downtime can mean failed checkouts, missed webhooks and support tickets from every customer.

App Hosting Platforms reliability at a glance
- Across the 12 ranked app hosting platforms, average 90-day uptime is 98.85%. Reliability scores range from 95.1 (DigitalOcean App Platform) to 33.1 (Upsun (Platform.sh)).

- Fly.io reported the most incidents (53 in 90 days).
What to check before you choose a app hosting platform
- Separate runtime incidents from build and dashboard incidents. A deploy pipeline outage delays fixes, but a runtime or edge outage takes your app offline.
- Check incident history for the specific region you would deploy to, since many outages hit one region or data center.
- Ask whether running apps keep serving traffic when the control plane or API is down, and whether you can roll back without a new build.
- For critical apps, keep DNS and a static fallback page outside the platform so you can redirect traffic during a long outage.

How do you measure app hosting platform reliability?
We poll each vendor's public status page every few minutes, record every incident, and run our own uptime checks against each vendor's login and customer-facing pages. Uptime (40%), incident frequency (20%), average time to resolve (20%) and transparency (20%) combine into one score out of 100.
How often are these rankings updated?
Continuously. Status pages and uptime checks run every five minutes and scores are recalculated several times an hour.
Can vendors pay to rank higher?
