Umami vs Grafana Loki

Umami vs Grafana Loki: at a glance
What is Umami?
Umami spent late 2025 patching Next.js CVEs, then shipped Boards and Session Replay in v3.1.0.
The window splits sharply. Four of six releases are December 2025 patches across the v2 and v3 lines, all responding to the same Next.js and React security advisories plus Docker build breakage — several shipped within days of each other because the first fix updated Next.js without the affected React versions. Then v3.1.0 in April 2026 delivered custom dashboards as Boards, Session Replay, Web Vitals performance tracking, a redesigned share page, and a large batch of fixes.
What is Grafana Loki?
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

Umami spent late 2025 patching Next.js CVEs, then shipped Boards and Session Replay in v3.1.0.
◆ Current state
The window splits sharply. Four of six releases are December 2025 patches across the v2 and v3 lines, all responding to the same Next.js and React security advisories plus Docker build breakage — several shipped within days of each other because the first fix updated Next.js without the affected React versions. Then v3.1.0 in April 2026 delivered custom dashboards as Boards, Session Replay, Web Vitals performance tracking, a redesigned share page, and a large batch of fixes.
◆ Where it's heading
The security cluster is a framework dependency showing its cost — an analytics tool inheriting its release schedule from Next.js advisories. v3.1.0 is where product work resumes, and its content is telling: Session Replay and Web Vitals move Umami past pageview counting into behaviour and performance, which is the territory occupied by heavier commercial analytics rather than the lightweight privacy-first tools it grew up alongside.
◆ Prediction
Expect the next releases to build on Boards and Session Replay rather than return to the counting core, since both are new surfaces that arrived with a single release and no follow-up yet.
Grafana Loki
6.3ANALYTICS
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
◆ Current state
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
◆ Where it's heading
Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
◆ Prediction
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
