What is Missive?
Native AI credits and a steady drip of MCP integrations turn Missive into a credible AI inbox.
Missive is releasing on a roughly bi-weekly cadence, with most of the energy going into the AI assistant: tool-call introspection, native AI credits as an alternative to BYOK, MCP integrations with Todoist and ClickUp, and an Activity feed that lets the assistant analyze inbox/team-inbox/label state on demand. Calendar UX got drag-to-move and resize, Analytics gained inline time-series charts, and OpenAI EU residency support was added for European customers.
What is Misskey?
Misskey's next release cuts server memory by up to 140MB with a new start script.
Misskey, the ActivityPub social server, follows a monthly alpha-to-release cycle. The 2026.11.0 alpha adds a production start script, node ./scripts/start.mjs, that avoids leftover resident processes and cuts memory use by 70 to 140MB; official Docker images use it automatically. It also carries the improved display of quote posts from Mastodon and other software, plus a batch of deck, chat and push-notification fixes. October's 2026.10.1 moved to Sentry SDK v11.
Missive vs Misskey: editorial side-by-side
Missive
5.0COMMS
Native AI credits and a steady drip of MCP integrations turn Missive into a credible AI inbox.
◆ Current state
Missive is releasing on a roughly bi-weekly cadence, with most of the energy going into the AI assistant: tool-call introspection, native AI credits as an alternative to BYOK, MCP integrations with Todoist and ClickUp, and an Activity feed that lets the assistant analyze inbox/team-inbox/label state on demand. Calendar UX got drag-to-move and resize, Analytics gained inline time-series charts, and OpenAI EU residency support was added for European customers.
◆ Where it's heading
The product is methodically converging the team-inbox surface with an AI assistant that has actual context — not just a sidebar chatbot but one that can mention specific labels, fetch conversations, and reach into external task systems via MCP. The AI Credits launch is the strategic move; it ends the BYOK-only friction and starts building a new revenue line on inference markup. Continued MCP integration additions suggest more partner connections ahead.
◆ Prediction
Expect more MCP integrations (Linear, Asana, Notion are obvious next targets), AI Credit consumption analytics for admins, and likely a paid AI tier or assistant-only seat type once the credit usage data is in. Calendar will probably see more two-way sync polish given the drag-to-move foundation.
Misskey
5.0COMMS
Misskey's next release cuts server memory by up to 140MB with a new start script.
◆ Current state
Misskey, the ActivityPub social server, follows a monthly alpha-to-release cycle. The 2026.11.0 alpha adds a production start script, node ./scripts/start.mjs, that avoids leftover resident processes and cuts memory use by 70 to 140MB; official Docker images use it automatically. It also carries the improved display of quote posts from Mastodon and other software, plus a batch of deck, chat and push-notification fixes. October's 2026.10.1 moved to Sentry SDK v11.
◆ Where it's heading
Recent releases lean on operator concerns: security fixes, Sentry configuration, safe startup on bad queue config, and now memory footprint. Federation polish with non-Misskey software continues alongside, which matters for smaller self-hosted instances.
◆ Prediction
2026.11.0 is likely to go final within weeks carrying the start script, following the pattern of alphas reaching release in two to three weeks. Further memory or query-reduction work looks likely given the server fixes trimming unneeded user-data lookups.
