OpenReplay vs Apache SeaTunnel
A side-by-side editorial comparison of OpenReplay and Apache SeaTunnel — release velocity, themes, recent moves, and the top alternatives to consider.
OpenReplay vs Apache SeaTunnel: at a glance
What is OpenReplay?
OpenReplay lets self-hosters block the hosts a recorded session can make its asset cacher fetch.
OpenReplay's feed is still backend maintenance across the 1.25 to 1.27 lines. On Nov 3 it added ASSETS_DENY_HOSTS so the asset cacher refuses chosen hosts before any DNS lookup, after a probe session crash-looped a pod. The same day brought a fix for EE 1.26 images that crashed on start and a product-analytics user fix backported to three lines.
What is Apache SeaTunnel?
SeaTunnel 3.0 ends a six-month gap with 927 PRs and 30 new connectors.
Apache SeaTunnel shipped 3.0.0 on 30 September, its first release since March: 927 merged PRs, 30 new connectors (BigQuery, Salesforce, Google and TikTok Ads, Stripe, Shopify, Mem0, Deep Lake and more), a Python transform, PostgreSQL CDC add-column schema evolution and connectivity dry-runs for S3 and Kafka sources. The prior 2.3.13 release made large files splittable across readers.

OpenReplay
5.0ANALYTICS
OpenReplay lets self-hosters block the hosts a recorded session can make its asset cacher fetch.
◆ Current state
OpenReplay's feed is still backend maintenance across the 1.25 to 1.27 lines. On Nov 3 it added ASSETS_DENY_HOSTS so the asset cacher refuses chosen hosts before any DNS lookup, after a probe session crash-looped a pod. The same day brought a fix for EE 1.26 images that crashed on start and a product-analytics user fix backported to three lines.
◆ Where it's heading
The work is hardening the self-hosted stack: safer asset fetching, startup crash fixes and the same patch landing on several release lines. The deny list moving into a shared package suggests asset handling is being made consistent across versions. No new user-facing features have appeared in recent entries.
◆ Prediction
Expect ASSETS_DENY_HOSTS to reach the 1.25 line next, following the usual backport pattern.
Apache SeaTunnel
0.0ANALYTICS
SeaTunnel 3.0 ends a six-month gap with 927 PRs and 30 new connectors.
◆ Current state
Apache SeaTunnel shipped 3.0.0 on 30 September, its first release since March: 927 merged PRs, 30 new connectors (BigQuery, Salesforce, Google and TikTok Ads, Stripe, Shopify, Mem0, Deep Lake and more), a Python transform, PostgreSQL CDC add-column schema evolution and connectivity dry-runs for S3 and Kafka sources. The prior 2.3.13 release made large files splittable across readers.
◆ Where it's heading
The connector catalogue is moving beyond databases and file stores into SaaS APIs and ad platforms, plus vector and memory stores. Schema evolution in CDC sources keeps widening, one database at a time, and the major version resets expectations after a lengthening release interval.
◆ Prediction
Expect 3.0.x patch releases fixing the new connectors, given how much landed in one version.
