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 Resend?

Resend keeps widening from a raw email API into agent-native tooling and audience management.

Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

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.

5.0

Resend keeps widening from a raw email API into agent-native tooling and audience management.

◆ Current state

Resend remains a developer-first email platform, but its recent surface area is splitting in two directions. One track is agent-native access — an MCP server, a CLI built for humans and AI agents, a Claude Code plugin, and AI-assisted authoring. The other is audience and content tooling — bulk CSV contact import, in-email charts, and richer broadcast composition — pushing it past pure transactional sending.

◆ Where it's heading

The pattern across these releases is Resend trying to own both ends of the email stack: the programmatic API developers integrate, and the audience layer that marketing tools like Mailchimp and Loops occupy. The agent-native investments suggest it expects a growing share of email to be triggered and composed by AI tools rather than hand-written code. Contact import at scale is the clearest sign it wants the audience database, not just the send.

◆ Prediction

Expect the audience side to deepen next — segmentation, list management, or analytics on top of the imported contacts — to match the broadcast and authoring features already shipped.
