MotherDuck vs OpenReplay: at a glance
What is MotherDuck?
MotherDuck's Flights graduate from Preview with HIPAA support, unlocking regulated-industry analytics on DuckDB.
MotherDuck has been building its enterprise layer on top of DuckDB's cloud execution model: RBAC arrived in July, table-level sharing and custom roles landed in August, and Flights—the serverless job execution layer—reached general availability in September with HIPAA BAA coverage. In parallel, Guides (markdown context files that agents read automatically through the MCP server) and a CLI in preview point toward a scriptable, version-controlled analytics workflow for agentic SQL sessions.
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.

MotherDuck's Flights graduate from Preview with HIPAA support, unlocking regulated-industry analytics on DuckDB.
◆ Current state
MotherDuck has been building its enterprise layer on top of DuckDB's cloud execution model: RBAC arrived in July, table-level sharing and custom roles landed in August, and Flights—the serverless job execution layer—reached general availability in September with HIPAA BAA coverage. In parallel, Guides (markdown context files that agents read automatically through the MCP server) and a CLI in preview point toward a scriptable, version-controlled analytics workflow for agentic SQL sessions.
◆ Where it's heading
Two tracks are running simultaneously: enterprise compliance (HIPAA, RBAC, table-level security, org-wide visibility) and developer tooling (CLI, Guides, remote DB creation, Favorites). The Guides feature is the most interesting signal—it's MotherDuck's answer to the problem of AI agents rediscovering the same SQL conventions every session, by giving teams a way to codify context that agents read automatically.
◆ Prediction
SOC 2 Type II attestation or expanded compliance certifications are likely in the next two quarters given the pace of enterprise access controls. The CLI and Guides combination points toward a GitOps-style analytics workflow where data logic lives in version control alongside application code.
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.
