What is Supabase?
Supabase is reversing its biggest security default - public-schema tables no longer auto-exposed via PostgREST.
The headline shipping move is a deliberate change to Supabase's security posture: new projects can opt out of automatic Data API and GraphQL exposure for public-schema tables, with broader defaults flipping in May. Around it: an OAuth 2.1 compliance fix, an RLS Tester preview to make policy verification possible from the UI, and a steady drumbeat of platform improvements summarized in the monthly developer update.
What is Knock?
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.

Supabase
6.3INFRA · APISDEVOPS
Supabase is reversing its biggest security default - public-schema tables no longer auto-exposed via PostgREST.
◆ Current state
The headline shipping move is a deliberate change to Supabase's security posture: new projects can opt out of automatic Data API and GraphQL exposure for public-schema tables, with broader defaults flipping in May. Around it: an OAuth 2.1 compliance fix, an RLS Tester preview to make policy verification possible from the UI, and a steady drumbeat of platform improvements summarized in the monthly developer update.
◆ Where it's heading
Supabase is rebuilding the security defaults that made it fast to start with but easy to misconfigure. Combine the no-auto-expose change with the RLS Tester preview and the direction is clear: the platform is moving from convention-based exposure to explicit, testable access control. The OAuth compliance fix and developer updates suggest steady investment in standards conformance rather than new product surface this window.
◆ Prediction
Expect the no-auto-expose default to apply to existing projects (with a long opt-out runway), and the RLS Tester to graduate from preview into the dashboard as a first-class panel. Continued breaking-change drumbeat tied to OAuth/OIDC compliance is likely.
Knock
6.3INFRA · APIS
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
◆ Current state
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.
◆ Where it's heading
The direction is toward less engineering involvement per change — agents, dashboard-built audiences, and hosted end-user UI all shorten the code path. Integrations like the Shopify data source extend Knock's triggers into commerce events, broadening what notifications can be driven by. The agent and the dashboard keep absorbing tasks that previously required custom code.
◆ Prediction
The next moves likely deepen the agent (more surfaces or skills) and add further data sources, continuing the shift toward dashboard- and agent-driven configuration over hand-written integration code.
