Keila vs OneSignal
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.
OneSignal's feed pushes messaging strategy and RCS, with AI-native product news just offstage.
The tracked OneSignal feed is mostly its blog: SMS/RCS strategy, engagement-platform buyer advice, and customer playbooks. Just outside the classified window sit genuine product moves — a OneSignal MCP Server and OneSignal AI, plus cross-channel deduplication tooling. The visible classified entries are positioning content rather than releases.
OneSignal is framing itself as an omnichannel engagement platform that helps brands build owned, algorithm-independent audiences, with RCS and AI-native workflows as the differentiators. The MCP/AI announcements suggest the product is moving toward being driven from AI-native tooling.
Expect more RCS and owned-audience content, with continued buildout of the AI/MCP surface hinted at in adjacent entries; the classified window itself shows no release.
