A side-by-side editorial comparison of Curator.io and Postiz — release velocity, themes, recent moves, and the top alternatives to consider.
Curator.io adds two-factor sign-in after patching its servers for October's PHP CVEs
Curator.io embeds social feeds on websites and publishes monthly release notes. October added email verification and two-factor authentication, after a separate notice that its servers were patched for two critical PHP vulnerabilities on October 22. The surrounding months added self-serve API key resets, plan-bound API access, schedules and Media Library work, with connector fixes in every release.
Postiz encrypts channel tokens and lets agents hand out channel-connect links
The 13 November release adds opt-in encryption of channel tokens at rest (local key or AWS KMS), connect links that let the public API or an MCP agent send someone a link to add a channel, Amazon SES for email and 20-item Instagram carousels with alt text. It also closes two access-control holes: plain members could call billing routes, and post saves could carry another organization's ids. October's release added preview comments and a self-hosted MCP connector.

Account security is the newest thread, joining the steady upkeep of social source connectors that dominates every release.
Connector fixes will keep filling the monthly notes; the entries do not show what follows 2FA.

Security and agent access now ship together. Each release hardens the self-hosted install while giving MCP agents and the API more of the workflow, from preview links in October to onboarding a client's channel in November.
Expect more MCP and API actions around client onboarding and review, and further access-control audits given two fixes in this release alone.
