What is Keila?

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.

What is Gumloop?

Gumloop is building the agent-app platform — addressable URLs, interactive artifacts, MCP-native everything.

Gumloop is shipping at a punishing weekly cadence, releasing 4–8 distinct capabilities per drop. Recent themes: every agent becomes addressable (Hosted Pages on gumloopagents.com), every artifact becomes interactive (MCP Artifacts read and write external systems), every workflow becomes longer-running (1-hour subagents, queued steering). The product is converging on an opinionated answer to 'what is the unit of agentic software.'

Self-hosted newsletter tool laying groundwork to expand into transactional email

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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 is building the agent-app platform — addressable URLs, interactive artifacts, MCP-native everything.

◆ Current state

Gumloop is shipping at a punishing weekly cadence, releasing 4–8 distinct capabilities per drop. Recent themes: every agent becomes addressable (Hosted Pages on gumloopagents.com), every artifact becomes interactive (MCP Artifacts read and write external systems), every workflow becomes longer-running (1-hour subagents, queued steering). The product is converging on an opinionated answer to 'what is the unit of agentic software.'

◆ Where it's heading

Gumloop is positioning itself as the platform where teams build, share, and run multi-step agents the way they once built Zapier workflows — but with MCP as the universal connector, artifacts as the UI primitive, and hosted URLs as the distribution model. The Partner Program, Enterprise Data Drains, and audit/credential controls signal a serious enterprise push under the platform expansion.

◆ Prediction

Expect the agent-as-app pattern to deepen: custom domains, embeddable agents, marketplaces. Lazy tool loading and longer subagents point at preparing for far more complex agent topologies. The next missing piece is observability — given Organization Analytics already exists, agent-level tracing and replay are likely on deck.
