Postmark vs Misskey: at a glance
What is Postmark?
Postmark adds its own SOC 2 Type 2 report to a run of security work.
Postmark's MCP server has 24 tools and delivery diagnostics, and the team has spent the autumn on account security: webhook verification and monitoring, IP Allowlisting for API sending, and 2FA on the free Developer plan. On November 5 it published its first standalone SOC 2 Type 2 report.
What is Misskey?
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.
Postmark vs Misskey: editorial side-by-side
Postmark
2.5COMMS
Postmark adds its own SOC 2 Type 2 report to a run of security work.
◆ Current state
Postmark's MCP server has 24 tools and delivery diagnostics, and the team has spent the autumn on account security: webhook verification and monitoring, IP Allowlisting for API sending, and 2FA on the free Developer plan. On November 5 it published its first standalone SOC 2 Type 2 report.
◆ Where it's heading
Postmark is pairing agent-facing tooling (Skills, the MCP server) with the compliance and security controls larger buyers ask for. The SOC 2 report removes a procurement blocker rather than adding a feature.
◆ Prediction
Expect more admin and compliance controls, such as audit logs or SSO, alongside further MCP server tools.
Misskey
5.0COMMS
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
◆ Current state
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.
◆ Where it's heading
Misskey's last two cycles are about making servers cheaper and safer to run: tighter Sentry data-collection defaults in 2026.10, lower memory and newer Node versions in 2026.11. Each one carries a breaking requirement that admins must check before upgrading.
◆ Prediction
Expect 2026.11.x patch releases for upgrade problems, especially around custom NODE_OPTIONS and systemd units. The entries do not show what the next feature cycle will target.
