Code Hosting & CI/CD · 2026 reliability ranking

Most Reliable Code Hosting & CI/CD Platforms (2026)

We ranked 15 code hosting & CI platforms by real-world reliability over the last 90 days, using 190 status page incidents and our own around-the-clock uptime checks. Code hosting and CI/CD platforms hold a team's source code and run the builds, tests and deployments that ship it, so an outage stops merges, releases and hotfixes at the same time. For a small software team that can mean a day of blocked work or an urgent fix that cannot reach production. Delayed or stuck build queues are the most common problem, and they cost developer hours even when the site itself stays up.

What to check before you choose a code hosting & CI platform

Check how often builds are delayed or queued, not just full outages. Slow job starts are the most common incident and quietly eat developer time.
Separate Git hosting from CI: if your repository host is down you can't push, but if only CI is down you can usually still merge and deploy by hand.
Look at the runner types you need (Linux, macOS, Windows, self-hosted) and their own incident history, since macOS and hosted runners often fail separately.
Keep a way to ship an urgent fix without the platform, such as a documented manual deploy or a mirror of your repository.

Frequently asked questions

What is the most reliable code hosting & CI platform?

Based on the last 90 days of data, Bitrise is the most reliable code hosting & CI platform we track, with a reliability score of 88.6/100 and 99.90% uptime.

How do you measure code hosting & CI 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?

No. Sponsored placements are clearly labelled, shown separately from the rankings and never change a vendor's score.
