OpenObserve vs OpenReplay: at a glance
What is OpenObserve?
OpenObserve's 1.1 line settles into patch releases: 1.1.2 backports PromQL and five other fixes.
OpenObserve promoted 1.1.0 to stable after three release candidates and has shipped two patches since. 1.1.1 stopped tantivy index builds from fsyncing scratch files and made the metrics index and WAL pack always-on; 1.1.2 fixes constant hash ordering in PromQL streaming scans and ports five more fixes onto the 1.1 branch. The cycle overall was plumbing: memory-bounded caches, faster PromQL quantiles, a new MIDX encoding and a flag-gated Product Analytics.
What is OpenReplay?
OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.
On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

OpenObserve
5.0ANALYTICS
OpenObserve's 1.1 line settles into patch releases: 1.1.2 backports PromQL and five other fixes.
◆ Current state
OpenObserve promoted 1.1.0 to stable after three release candidates and has shipped two patches since. 1.1.1 stopped tantivy index builds from fsyncing scratch files and made the metrics index and WAL pack always-on; 1.1.2 fixes constant hash ordering in PromQL streaming scans and ports five more fixes onto the 1.1 branch. The cycle overall was plumbing: memory-bounded caches, faster PromQL quantiles, a new MIDX encoding and a flag-gated Product Analytics.
◆ Where it's heading
After 1.0 GA bundled AI observability, SLOs and database monitoring, the team is hardening storage, indexing and query internals rather than widening the surface. A maintained 1.1 branch receiving backports means stable lines are now supported while main moves on. Product Analytics is shipping dark behind a flag.
◆ Prediction
Expect further 1.1.x patches on PromQL and indexing, with Product Analytics the candidate headline once enabled by default; the entries don't say when.
OpenReplay
5.0ANALYTICS
OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.
◆ Current state
On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.
◆ Where it's heading
The release feed is all maintenance: dependency and runtime upgrades backported to several self-hosted lines at once, published as timestamped backup tags without feature notes. The quick follow-up fix shows the pgx migration is touching real query paths.
◆ Prediction
Expect more backup tags as the pgx v5 change reaches 1.22 and any further query fixes land; nothing in the entries points to a feature release.
