What is Gumloop?
Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.
Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.
What is Postiz?
Postiz is maturing from scheduler into collaborative, agent-reachable publishing infrastructure.
Postiz ships large, infrequent releases, roughly every two months. The latest, v2.25, adds threaded comments on post previews, a self-hosted MCP connector, a responsive layout pass, and a sweep of 50+ provider fixes that turn opaque failures into readable, correctly retried errors. The previous release focused on memory-efficient streamed uploads and duplicate-post protection.
Gumloop vs Postiz: editorial side-by-side
Gumloop
7.5MKT AUTO
Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.
◆ Current state
Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.
◆ Where it's heading
The product is moving from building agents to operating them at org scale, and artifacts are turning into small apps that can control agents themselves. Model access is also being made easier to manage, with families, deprecation dates and fallback visibility.
◆ Prediction
Expect more of the SDK exposed to artifacts and further evaluation and Insights controls at the usual weekly pace; the entries don't show pricing changes.
Postiz
2.5MKT AUTO
Postiz is maturing from scheduler into collaborative, agent-reachable publishing infrastructure.
◆ Current state
Postiz ships large, infrequent releases, roughly every two months. The latest, v2.25, adds threaded comments on post previews, a self-hosted MCP connector, a responsive layout pass, and a sweep of 50+ provider fixes that turn opaque failures into readable, correctly retried errors. The previous release focused on memory-efficient streamed uploads and duplicate-post protection.
◆ Where it's heading
Two threads run through the releases: operational reliability for self-hosters (streaming, retry semantics, security patches) and opening the product to AI clients through MCP. Review workflows like preview comments point at team and agency use rather than solo scheduling.
◆ Prediction
The next release likely deepens MCP coverage and approval-style collaboration around previews; the cadence suggests it lands in roughly two months.
