OpnForm vs SendPortal: at a glance
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.
What is SendPortal?
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.

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.
SendPortal
2.5MKT AUTO
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
◆ Current state
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.
◆ Where it's heading
A major version followed by fixes to the installer suggests the project is active again and new installs are being tested. With two tagged releases six years apart, there's no cadence to read yet.
◆ Prediction
If v4 is a real revival, more point releases should follow within weeks; another long silence would mean v4 was a one-off.
