Activepieces vs Keila: at a glance
What is Activepieces?
ActivePieces is fighting a multi-front release instability with simultaneous hotfix trains across three version lines.
ActivePieces is currently running three parallel release trains — 0.87.x hotfixes, 0.88.x hotfixes, and an unstable 0.90.x track — with the recent entries dominated by worker reliability issues: piece cache prewarm timing bugs, health server reconnect failures, and OAuth2 regressions that had to be reverted. The stable release line is 0.88.4-based; the 0.90.x line is explicitly unstable and includes Claude-assisted piece form improvements for Google Sheets and Custom API Call steps.
What is Keila?
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.

Activepieces
5.0MKT AUTO
ActivePieces is fighting a multi-front release instability with simultaneous hotfix trains across three version lines.
◆ Current state
ActivePieces is currently running three parallel release trains — 0.87.x hotfixes, 0.88.x hotfixes, and an unstable 0.90.x track — with the recent entries dominated by worker reliability issues: piece cache prewarm timing bugs, health server reconnect failures, and OAuth2 regressions that had to be reverted. The stable release line is 0.88.4-based; the 0.90.x line is explicitly unstable and includes Claude-assisted piece form improvements for Google Sheets and Custom API Call steps.
◆ Where it's heading
The high volume of hotfixes on multiple branches suggests the 0.88.x stable line hit real operational issues in production deployments, particularly around worker lifecycle management. The simultaneous 0.90.x unstable track is where new piece improvements are landing — but shipping that in parallel with a hotfix storm creates a split-attention dynamic that could slow the stabilization of either track. A consolidation to a single stable release line would be the cleaner path forward.
◆ Prediction
The 0.90.x unstable track will likely graduate to stable once the worker prewarm and health server issues are fully resolved in 0.87.x and 0.88.x. Expect more piece-level form improvements as the Claude-assisted development pattern seen in 0.90.4 continues.
Keila
2.5MKT AUTO
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
◆ Current state
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.
◆ Where it's heading
Keila's recent releases — v0.30.0's transactional email API, v0.20.0's new email scheduler, and now v0.30.3's performance work — show a project that is consolidating its architecture before broadening its feature set. The self-hosting focus remains; the additions to system mailer configurability suggest the project is listening to operators running Keila in production with non-standard SMTP setups.
◆ Prediction
Transactional email capabilities from v0.30.0 will likely expand — more API endpoints, webhook delivery events, or better unsubscribe handling for transactional vs. campaign messages. Performance tooling for large lists will continue as the Liquid caching work surfaces the right optimization targets.
