What is Skipper?

One pull request per version tag, and most of them are dependency bumps.

Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.

What is Resend?

Resend is turning an email API into something other people build products on.

Two months of releases split cleanly. One half is dashboard housekeeping — template folders, suppression management, Open Graph previews in the editor, Message-ID exposed on webhooks for threading. The other half is platform plumbing: a hosted MCP server, OAuth 2.1 with PKCE, a Claude connector, a Codex marketplace plugin, and automatic revocation of API keys leaked to GitHub.

Skipper vs Resend: editorial side-by-side

S
Skipper
INFRA · APIS
5.0

One pull request per version tag, and most of them are dependency bumps.

◆ Current state

Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.

◆ Where it's heading

The visible work is maintenance of an already-stable proxy rather than feature development. What the test changes hint at is where the correctness concerns sit: an OPA policy test updated to explicitly deny truncated request bodies, because oversized JSON cannot be fully parsed and a policy that ignores input.truncated_body can be bypassed. That is authorization-under-load hardening, and it is the most interesting thing in the window even though it landed as a test.

◆ Prediction

The per-PR tagging rhythm will continue producing several versions a week regardless of change size. Readers tracking this product should expect the meaningful changes to be a small minority of the tags.

Resend is turning an email API into something other people build products on.

◆ Current state

Two months of releases split cleanly. One half is dashboard housekeeping — template folders, suppression management, Open Graph previews in the editor, Message-ID exposed on webhooks for threading. The other half is platform plumbing: a hosted MCP server, OAuth 2.1 with PKCE, a Claude connector, a Codex marketplace plugin, and automatic revocation of API keys leaked to GitHub.

◆ Where it's heading

The center of gravity has moved from features a developer uses to interfaces another product consumes. OAuth is the hinge — with it, third parties can act on a user's Resend account without holding a key, which is the precondition for the connector and plugin distribution Resend is now shipping into Claude, Codex and Cursor. Tracking the 2026-07-28 MCP spec within nine days says they intend to stay current with that surface rather than treat it as a side project.

◆ Prediction

The pattern points to scoped OAuth permissions and a listing surface for third-party Resend apps, plus continued fast-following of MCP spec revisions. Nothing in these entries indicates a pricing or deliverability change.
