What is Postiz?

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

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.

What is TinaCMS?

TinaCMS 3.13.0 ships media renaming, image type restrictions, and drops 1.3MB from the admin bundle by lazy-loading Mermaid.

TinaCMS is a Git-backed headless CMS shipping as a monorepo of npm packages. The 3.13.0 release is the substantive one this cycle: media renaming from the Media Manager (with editorial workflow support for protected branches), image field `accept` attribute for restricting file types, semantic `<thead>/<th>` in markdown tables (breaking CSS change), and a significant bundle reduction — the Mermaid library moved to a lazy-loaded chunk, trimming the admin entry from 6.3MB to 5.7MB gzipped.

Postiz vs TinaCMS: editorial side-by-side

P
Postiz
MARKETING
2.5

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.

6.3

TinaCMS 3.13.0 ships media renaming, image type restrictions, and drops 1.3MB from the admin bundle by lazy-loading Mermaid.

◆ Current state

TinaCMS is a Git-backed headless CMS shipping as a monorepo of npm packages. The 3.13.0 release is the substantive one this cycle: media renaming from the Media Manager (with editorial workflow support for protected branches), image field `accept` attribute for restricting file types, semantic `<thead>/<th>` in markdown tables (breaking CSS change), and a significant bundle reduction — the Mermaid library moved to a lazy-loaded chunk, trimming the admin entry from 6.3MB to 5.7MB gzipped.

◆ Where it's heading

TinaCMS is building out content management completeness — media lifecycle operations (rename was a notable gap), richer field validation, and better editor fidelity (markdown hard breaks, table semantics). Bundle size attention suggests the product is being tuned for real-world adoption where admin load time matters. Session expiry flow now handles the case cleanly, which matters for TinaCloud commercial accounts.

◆ Prediction

The editorial workflow (branch-based content workflows for protected repos) will likely get further polish as media operations expand. The broken admin bundle size trend suggests performance optimization may become a sustained focus.
