What is Coolify?
Coolify is in a sustained security-hardening run while the v4 beta inches forward.
Coolify is releasing roughly weekly beta builds dominated by security and reliability work: mass-assignment protection, query scoping, input validation, encrypted webhook secrets, accidental-prune protection. Each release also slips in small bug fixes and the occasional new service template. The same release is published across two feeds, so duplicates are common in the changelog.
What is Prometheus?
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.
Coolify vs Prometheus: editorial side-by-side
Coolify
2.5DEVOPS
Coolify is in a sustained security-hardening run while the v4 beta inches forward.
◆ Current state
Coolify is releasing roughly weekly beta builds dominated by security and reliability work: mass-assignment protection, query scoping, input validation, encrypted webhook secrets, accidental-prune protection. Each release also slips in small bug fixes and the occasional new service template. The same release is published across two feeds, so duplicates are common in the changelog.
◆ Where it's heading
The product is hardening for production self-hosted use rather than expanding feature surface. Several recent fixes — team-scoped queries, locked properties, encryption for secrets — are the kind of multi-tenant defenses that matter when self-hosted PaaS instances start hosting more than one team's workloads. The v4 beta is converging toward stable, but security debt is still being paid down before that happens.
◆ Prediction
Expect a v4 GA cut once the security backlog drains and the new-template flow stabilizes, plus an explicit audit/security advisory listing the hardening work. New service templates will continue to drip in opportunistically.
Prometheus
5.0DEVOPS
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
◆ Current state
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.
◆ Where it's heading
PromQL is the centre of gravity. Features enter behind promql-experimental-functions or a dedicated flag, get renamed once while experimental (min/max to min_of/max_of), then graduate — first_over_time and duration expressions are the current graduates, start_timestamp the next candidate behind use-start-timestamps. The API is simultaneously being tightened, with the stats parameter deprecated ahead of rejection in the next major and credential forwarding across redirects already removed in 3.13. Service discovery keeps absorbing clouds as their APIs change, OCI added and a Hetzner label dropped in the same release.
◆ Prediction
A 3.14.0 final should follow the release candidate within weeks, carrying the duration-expression and first_over_time promotions with it.
