What is Hello Bar?

Hello Bar grows a second surface: on-page widgets alongside the popups.

Hello Bar builds popups, bars and lead-capture forms for websites, with targeting rules, triggers and email-provider integrations behind them. July was an unusually dense month: a gamification popup builder with spin, scratch and loot-box mechanics, video as a media option, a shared asset library, an expanded Salesforce integration, and a new Widgets category holding a chat launcher and an AI summary button. An automatic scheduling feature, Campaigns, has been announced but is still marked coming soon.

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.

Hello Bar vs OpnForm: editorial side-by-side

2.5

Hello Bar grows a second surface: on-page widgets alongside the popups.

◆ Current state

Hello Bar builds popups, bars and lead-capture forms for websites, with targeting rules, triggers and email-provider integrations behind them. July was an unusually dense month: a gamification popup builder with spin, scratch and loot-box mechanics, video as a media option, a shared asset library, an expanded Salesforce integration, and a new Widgets category holding a chat launcher and an AI summary button. An automatic scheduling feature, Campaigns, has been announced but is still marked coming soon.

◆ Where it's heading

Two directions are visible. The popup builder is being deepened toward conversion mechanics — reward logic, video media, reusable assets — which is where this category competes. The more interesting one is Widgets, which puts persistent elements on the page that are not popups at all, including a router into WhatsApp, Messenger, Instagram, Telegram and SMS. Hello Bar is starting to sell presence on the page rather than interruptions on it.

◆ Prediction

Widgets launched with two entries and an explicit framing as a category, so the next move is more widgets rather than more popup types — a review, social proof or booking widget would fit the existing conversion pitch.

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.
