Highlight vs Grafana Loki: at a glance
What is Highlight?
Highlight grew from session replay into SQL-driven observability, then went quiet in August 2025.
Highlight is an open-source observability stack covering session replay, errors, logs, traces and metrics. Its last tagged self-hosted release, docker-v0.5.6, shipped in August 2025 with session-replay performance fixes and session restarts. Nothing has been tagged since.
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.
Highlight vs Grafana Loki: editorial side-by-side
Highlight
0.0ANALYTICS
Highlight grew from session replay into SQL-driven observability, then went quiet in August 2025.
◆ Current state
Highlight is an open-source observability stack covering session replay, errors, logs, traces and metrics. Its last tagged self-hosted release, docker-v0.5.6, shipped in August 2025 with session-replay performance fixes and session restarts. Nothing has been tagged since.
◆ Where it's heading
Through 2025 the releases added OpenTelemetry metrics ingest, a SQL editor and builder for graphs, SQL alerts and dashboards created from log and trace views. That pushed Highlight from a replay tool toward a general telemetry platform. The cadence then slowed from roughly monthly to a two-month gap before stopping.
◆ Prediction
The entries show no release in more than a year, so the self-hosted line's future is unclear. Any new tag would most likely be maintenance on session replay and OTel ingestion.
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.
