What is OpenReplay?

OpenReplay's feed is Helm chart bumps behind its asset-cacher deny list.

OpenReplay's entries since November 4 are automated backup tags on the 1.26 and 1.27 lines that only increment Helm chart versions for chalice, assist-api and assist-stats. The last functional change remains the November 3 ASSETS_DENY_HOSTS option, which lets self-hosters block hosts the asset cacher may fetch, alongside a fix for EE 1.26 images that crashed on start.

What is MotherDuck?

MotherDuck adds who-can-open controls to Dives and a SQL view of compute usage.

MotherDuck ships a weekly changelog. The November 12 release lets owners keep a Dive private or share it with roles, users or the whole organization, with matching GRANT READ ON DIVE commands; new Dives start private. Flight run access can now be managed in the UI, and Business plans can query hourly Duckling usage per user from MD_INFORMATION_SCHEMA.COMPUTE_USAGE. It lands a week after the redesign that put Agent Chat on the home screen.

OpenReplay vs MotherDuck: editorial side-by-side

O
OpenReplay
ANALYTICS
5.0

OpenReplay's feed is Helm chart bumps behind its asset-cacher deny list.

◆ Current state

OpenReplay's entries since November 4 are automated backup tags on the 1.26 and 1.27 lines that only increment Helm chart versions for chalice, assist-api and assist-stats. The last functional change remains the November 3 ASSETS_DENY_HOSTS option, which lets self-hosters block hosts the asset cacher may fetch, alongside a fix for EE 1.26 images that crashed on start.

◆ Where it's heading

The project is in a maintenance stretch, backporting fixes across 1.25 to 1.27 and repackaging charts. Nothing in recent entries points to new user-facing features.

◆ Prediction

Unclear from these entries; more chart-bump backup tags are likely until a 1.27.x release with notes appears.

6.3

MotherDuck adds who-can-open controls to Dives and a SQL view of compute usage.

◆ Current state

MotherDuck ships a weekly changelog. The November 12 release lets owners keep a Dive private or share it with roles, users or the whole organization, with matching GRANT READ ON DIVE commands; new Dives start private. Flight run access can now be managed in the UI, and Business plans can query hourly Duckling usage per user from MD_INFORMATION_SCHEMA.COMPUTE_USAGE. It lands a week after the redesign that put Agent Chat on the home screen.

◆ Where it's heading

The agent-first redesign made Dives and Flights the things people create; the releases since are about controlling who sees and runs them and what they cost. Governance that began with row- and column-level security in October now covers the agent-built objects too.

◆ Prediction

Next likely are finer controls on what Agent Chat can do on a user's behalf, or usage limits built on the new compute usage view, since both follow from the permissions and cost work in the last two releases.
