What is OpnForm?

OpnForm makes itself addressable by AI agents, with the permission model built in rather than bolted on

OpnForm is a form builder that spent the last three months stabilising the V2 platform it shipped in June, then began extending it. v2.4.0 is the largest step since V2: an MCP server and a portable Agent Plugin package let AI assistants create and preview private form drafts, hand them to the editor, and — after OAuth — manage forms, read and search submissions, pull form-level statistics and trigger async CSV exports. The same release adds native campaign attribution, capturing UTM parameters and ad click identifiers from standalone forms, embeds, SDK integrations and popups, then exposing them through submissions, webhooks, SDK events and CSV exports.

What is Postscript?

Postscript is handing SMS marketing to an agent that decides each subscriber's next message

Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.

OpnForm makes itself addressable by AI agents, with the permission model built in rather than bolted on

◆ Current state

OpnForm is a form builder that spent the last three months stabilising the V2 platform it shipped in June, then began extending it. v2.4.0 is the largest step since V2: an MCP server and a portable Agent Plugin package let AI assistants create and preview private form drafts, hand them to the editor, and — after OAuth — manage forms, read and search submissions, pull form-level statistics and trigger async CSV exports. The same release adds native campaign attribution, capturing UTM parameters and ad click identifiers from standalone forms, embeds, SDK integrations and popups, then exposing them through submissions, webhooks, SDK events and CSV exports.

◆ Where it's heading

The arc runs from platform (V2) through repair (2.1 and 2.2) through automation (2.3) to agent access (2.4), and each layer reuses the one under it. What distinguishes the MCP work is how much of it is authorization design rather than tool surface: delegated OAuth with PKCE, workspace scoping, revision conflict detection, private capability tokens, confirmation gates before publishing or trashing, and a hard rule that submission records cannot be deleted or restored through MCP at all. Self-hosted MCP ships disabled by default and requires Passport plus public HTTPS before it can be turned on.

◆ Prediction

The notes flag public ChatGPT directory registration as a separate, unfinished distribution step, so the next move is likely getting the Agent Plugin listed rather than adding more tools. Expect the usual self-hosted follow-up patches against the MCP guest-draft migrations this release introduces.

Postscript is handing SMS marketing to an agent that decides each subscriber's next message

◆ Current state

Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.

◆ Where it's heading

The centre of gravity is shifting from campaign tooling to per-subscriber decisioning. Shopper began as a responder, then gained a research surface over its own conversations, and now decides send timing and content for each individual. Alongside that, RCS is the delivery-side bet: webviews, dynamic product photos and tappable suggested replies all work to make the message thread the destination rather than a pointer to the storefront. Experimentation is being pushed into more of the journey rather than confined to campaign sends.

◆ Prediction

Expect the remaining hand-built primitives — static flows and manual segments — to be folded into Shopper's decisioning, and each new RCS capability to keep shipping with an automatic MMS or browser fallback so merchants can adopt it without maintaining a second path.
