Craft CMS vs OpnForm: at a glance
What is Craft CMS?
Craft CMS 6.0 is a full Laravel rewrite — alpha releases are shipping breaking API changes every week.
Craft CMS 6.0 is mid-alpha, with a complete architectural shift from Yii to Laravel as its foundation. The alpha cadence has been weekly or better, each release removing legacy event-based APIs and replacing them with modern Laravel patterns — service containers, Artisan commands, Inertia/Vue CP pages. Image handling was overhauled to intervention/image with libvips support and new format coverage (HEIC, JPEG XL). The 5.x line continues receiving security and bug patches in parallel.
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.

Craft CMS
5.0MKT AUTO
Craft CMS 6.0 is a full Laravel rewrite — alpha releases are shipping breaking API changes every week.
◆ Current state
Craft CMS 6.0 is mid-alpha, with a complete architectural shift from Yii to Laravel as its foundation. The alpha cadence has been weekly or better, each release removing legacy event-based APIs and replacing them with modern Laravel patterns — service containers, Artisan commands, Inertia/Vue CP pages. Image handling was overhauled to intervention/image with libvips support and new format coverage (HEIC, JPEG XL). The 5.x line continues receiving security and bug patches in parallel.
◆ Where it's heading
Every alpha release trades backward compatibility for a cleaner platform foundation. Plugin authors are absorbing breaking changes in batches, with a compatibility shim (yii2-adapter) as the bridge. The CP frontend is moving steadily to Inertia/Vue, and the fluent component APIs suggest a design system consolidation. Once the alpha phase closes, Craft 6 will require full plugin rewrites — the ecosystem disruption is the price of the architectural cleanup.
◆ Prediction
The next alpha releases will focus on stabilizing the plugin API surface and filling gaps in the Inertia/Vue CP migration. A beta tag is plausible within 2-3 months if the breaking-change cadence slows. Expect the yii2-adapter compatibility layer to become a first-party migration guide rather than a long-term support path.
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.
