Open-source social media scheduling and management platform.

After six weeks of nothing but security patches, Postiz ships reliability work on the posting path itself.

◆Current state
Postiz is an open-source, self-hostable social media scheduler. The visible record since March is dominated by urgent security releases — one PSA advisory in June, two GHSA advisories in March, each recommending immediate upgrade — with a single new network (MeWe) as the only integration work in that span. The August release breaks the pattern: provider media uploads now stream rather than buffering whole files in memory, a pending-post workflow guards against duplicate posts, and the MCP server got stability and OAuth fixes.
◆Where it's heading
The project is working on the parts that fail at scale rather than the parts that demo well. Streaming uploads is a worker-memory fix for large media, and duplicate-post protection addresses the failure mode that actually costs a scheduling tool its users' trust. That an MCP server exists and is being maintained puts Postiz on the agent-accessible path, but this release treats it as infrastructure to harden, not a surface to expand. The six-week gap between releases suggests a small maintainer group prioritizing correctness over cadence.
◆Prediction
Given that MCP OAuth is being fixed rather than built out, the next visible step is likely more provider integrations or a stable MCP release once the auth path settles. The security-release cadence makes another advisory-driven patch equally plausible.

    Streamed media uploads, duplicate-post protection & MCP fixes

    Media uploads stream instead of buffering entire files in memory, cutting worker memory use on large uploads, while a pending-post workflow prevents duplicate posts. The first release in six weeks that is not purely a security patch, and it targets the two failure modes that matter most in a scheduler.

    Security fix for advisory PSA-2026-NWZN9J

    Patches two GHSA security advisories

    Another immediate-upgrade security release, closing two GHSA advisories. For a self-hosted tool the upgrade burden falls on operators, which makes these releases more disruptive than they look.

    MeWe Integration, Integration Fixes & PR Quality

    Adds a MeWe integration plus a PR-quality CI workflow and OAuth connection fixes. The only new network in the visible window, which makes integration breadth look static.

    Fix for stripe to still post when no strike key has been set

    A narrow fix so posting still works when Stripe is not configured — relevant only to self-hosters running without billing. A first-time contributor patch.
