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.
What is Rollbar?
Rollbar's AI arc reaches its endpoint: the error tracker now opens the pull request.
Rollbar spent 2026 converting error tracking into an AI workflow, and the Resolve agent is where that lands — production errors now come back as pull requests carrying a fix, test results, and a root cause. The monetization moved with it: AI features bill against a credit pool sold separately from plan tier, with no per-seat charge. Around that core, the platform work has been deliberately unglamorous, covering account-wide API tokens, an MCP server, session replay timelines, and a settings UI rebuild.
Prometheus vs Rollbar: editorial side-by-side
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.
Rollbar
6.3DEVOPS
Rollbar's AI arc reaches its endpoint: the error tracker now opens the pull request.
◆ Current state
Rollbar spent 2026 converting error tracking into an AI workflow, and the Resolve agent is where that lands — production errors now come back as pull requests carrying a fix, test results, and a root cause. The monetization moved with it: AI features bill against a credit pool sold separately from plan tier, with no per-seat charge. Around that core, the platform work has been deliberately unglamorous, covering account-wide API tokens, an MCP server, session replay timelines, and a settings UI rebuild.
◆ Where it's heading
The product is moving from telling you what broke to handing you the change that fixes it, and each release since April closed part of that loop — root cause in April, cheap access to it in June, codebase reach via MCP and account tokens in July, code generation and test execution in August. Credits rather than seats are the pricing unit, which lets Rollbar put agent features on the free plan without cannibalizing tier upgrades. Moving code access onto a dedicated GitHub App suggests that reach is now treated as infrastructure rather than an integration.
◆ Prediction
Expect Resolve to exit beta with credit consumption as the primary lever, and the agent to reach past single-error fixes — the cross-project correlation and telemetry already assembled for root cause analysis are the obvious next inputs.
