Keila vs Gumloop
Side-by-side trajectory, velocity, and editorial themes.
Self-hosted newsletter tool laying groundwork to expand into transactional email
Keila is shipping steadily again after a roughly 10-month gap, with five releases since January 2026. The headline move is v0.20.0's new email scheduler and a migration from a recipients schema to a generic messages schema, explicitly framed as the foundation for transactional emails. Around it sit incremental gains: welcome emails, interaction-based segmentation, newsletter archives, a faster block/markdown editor, more translations, and performance indices.
The product is broadening from a pure newsletter tool toward a fuller email platform. The schema migration decouples sent-message records from campaigns and contacts, which the changelog says unlocks transactional email — a new capability surface, not just a newsletter improvement. Alongside, a wave of localization and editor/performance work suggests a push for both reach and polish.
Expect transactional email to land as a first-class feature on top of the new messages schema, plus continued automation primitives (welcome emails hint at more lifecycle messaging) and localization. The renewed release cadence looks likely to hold.
Gumloop turns agents into deployable apps while building out team governance underneath.
Gumloop is shipping weekly across two arcs: maturing agents from chat sessions into shareable, deployable software, and layering in the team controls a growing org needs — skill permission roles, team-level secrets, a notification center, and one-click access approvals. The standout is Hosted Pages, which publishes each agent on its own URL as a standalone app.
The product is moving from 'build automations and chat with agents' toward 'ship agents as apps your team and customers use,' with MCP as the connective layer. Artifacts gain external read/write via MCP, agents get richer HTML output and hosting, and the collaboration/permissions plumbing is being put in place to support that at organization scale.
Expect Hosted Pages and MCP-connected artifacts to converge into a fuller agent-app deployment story, with continued investment in roles, governance, and the MCP server catalog.
