n8n vs Keila
Side-by-side trajectory, velocity, and editorial themes.
n8n ships fast patch trains — mostly fixes and CVE bumps, with quiet work on AI-builder sandboxes.
n8n's feed is a high-frequency release train of point versions across parallel lines (2.2x and a 1.123.x backport branch), dominated by bug fixes, security patches, and CI changes. The substantive thread underneath is its AI builder: recent releases harden how Instance AI sandboxes persist and resume. Most individual entries are maintenance; the signal is in cadence and the sandbox work.
n8n is running a mature, security-conscious release process — fast CVE remediation (Trivy-driven dependency bumps, redaction enforcement) and steady editor fixes — while investing in making its AI workflow-builder sandboxes durable and resumable rather than ephemeral. That points toward AI-assisted automation becoming a first-class, reliable part of the product rather than an experiment.
Expect the rapid patch cadence and prompt security backports to continue, with incremental hardening of the AI builder's sandbox lifecycle. Whether the AI builder graduates into a headline capability is the open question these point releases don't yet answer.
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.
