What is Postiz?
Postiz encrypts channel tokens and lets agents send connect links for new channels.
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.
What is Gumloop?
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.

Postiz
2.5MKT AUTO
Postiz encrypts channel tokens and lets agents send connect links for new channels.
◆ Current state
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.
◆ Where it's heading
Postiz still ships large releases about every six weeks. The last three have moved it from a scheduler toward publishing infrastructure that other software and agents can drive, with MCP access, preview comments and now connect links. This release adds the security work, encrypted tokens and tenant isolation, that larger self-hosted and multi-organization deployments need.
◆ Prediction
The next release will likely extend connect links to platforms that need API keys or instance URLs, and keep tokens out of Temporal history, which this release describes as groundwork.
Gumloop
6.3MKT AUTO
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
◆ Current state
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.
◆ Where it's heading
Since 13.2 the releases have moved from what agents can do toward how a company controls them. 13.6 is the broadest step yet: approval rules, data redaction and secret handling now cover all agent activity, which is what security teams ask for before a wide rollout.
◆ Prediction
Expect Workforce Atlas to leave beta with more tags and reporting, and more enterprise controls such as audit exports built on the new guardrail records.
