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 Sulu?

Sulu adds AI disclosure fields to media, shipped to both supported lines the same minute

Sulu is a Symfony-based CMS for developer-built sites, released as a synchronised pair: every 3.0.x patch ships within a minute or two of the matching 2.6.x patch, carrying largely the same pull requests. The 3.0.9 / 2.6.26 pair is the most substantive in months. Media assets gain Origin and AI Disclosure information, delivered as a doctrine migration with new columns and an updated form metadata snapshot, and the AI platform integration now reports a reason when it turns a request down. Two-factor setup adds an authenticator app (TOTP) flow and a Google Authenticator method, and a deprecation batch retires AbstractRestController, RestControllerTrait, ApiWrapper and the persistence component repositories and traits.

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.

Sulu adds AI disclosure fields to media, shipped to both supported lines the same minute

◆ Current state

Sulu is a Symfony-based CMS for developer-built sites, released as a synchronised pair: every 3.0.x patch ships within a minute or two of the matching 2.6.x patch, carrying largely the same pull requests. The 3.0.9 / 2.6.26 pair is the most substantive in months. Media assets gain Origin and AI Disclosure information, delivered as a doctrine migration with new columns and an updated form metadata snapshot, and the AI platform integration now reports a reason when it turns a request down. Two-factor setup adds an authenticator app (TOTP) flow and a Google Authenticator method, and a deprecation batch retires AbstractRestController, RestControllerTrait, ApiWrapper and the persistence component repositories and traits.

◆ Where it's heading

Three threads run through the pairs and their balance has shifted. Editor and framework upkeep continue — Symfony 8 request bag replacements, PHPStan baselines kept green — but this release adds two things that aren't maintenance. The media provenance work puts AI disclosure into the content model itself rather than leaving it to editors, which is the shape of a CMS preparing for disclosure obligations. The controller and repository deprecations point the other way, at an API layer being cleared out ahead of whatever 3.x becomes, since 3.0 has otherwise read like a maintenance branch alongside 2.6.

◆ Prediction

Expect the deprecated REST controller and persistence layers to be removed in a future major, since deprecating four API surfaces in one release is how Sulu signals a rewrite is staged. Whether the AI disclosure fields are surfaced on the delivery side or stay editorial metadata isn't visible in these entries.
