Keila vs OpnForm: at a glance
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.
What is OpnForm?
OpnForm added a full MCP server in v2.4 — AI assistants can now build, preview, and manage forms without touching the UI.
OpnForm shipped its MCP server in v2.4 (August 2026) and spent v2.5 hardening the guest-first flow: forms can now be built from Claude, Cursor, ChatGPT, or Codex without an account, with read-only previews before any data is saved. The official OpenAI plugin is distributed and verified. v2.3 added Make/Albato integrations, AI formula generation for computed variables, and an audio form block. The product has moved from a self-hosted form tool to a tool explicitly designed for AI agent workflows.
Keila vs OpnForm: editorial side-by-side
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.
OpnForm
6.3MKT AUTO
OpnForm added a full MCP server in v2.4 — AI assistants can now build, preview, and manage forms without touching the UI.
◆ Current state
OpnForm shipped its MCP server in v2.4 (August 2026) and spent v2.5 hardening the guest-first flow: forms can now be built from Claude, Cursor, ChatGPT, or Codex without an account, with read-only previews before any data is saved. The official OpenAI plugin is distributed and verified. v2.3 added Make/Albato integrations, AI formula generation for computed variables, and an audio form block. The product has moved from a self-hosted form tool to a tool explicitly designed for AI agent workflows.
◆ Where it's heading
The MCP investment is the clearest strategic signal in OpnForm's recent history: two consecutive major releases have been organized around making forms AI-native — first adding the server, then hardening the security and guest-first creation flow. Computed variables gaining PDF support and AI formula generation in the same cycle completes a workflow where an AI agent can construct a form, define computed logic, and generate a submission PDF without human intervention.
◆ Prediction
The next focus will be MCP submission handling — an AI agent that can build a form should also be able to query and act on its submission data. v2.4 added submission reading via MCP; expect richer filtering, aggregations, and webhook-triggered agent actions in the next release.
