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 OpenEMM?

OpenEMM ships versioned builds on schedule, with no notes on what changed.

OpenEMM moved to its 26.05 line in July with a full frontend and backend GA build. Since then only frontend builds have followed (26.05.111 in September, 26.05.132 in October). Earlier lines (25.11, 25.04) got maintenance releases into December 2025. No entry describes actual changes.

Hello Bar vs OpenEMM: 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.

2.5

OpenEMM ships versioned builds on schedule, with no notes on what changed.

◆ Current state

OpenEMM moved to its 26.05 line in July with a full frontend and backend GA build. Since then only frontend builds have followed (26.05.111 in September, 26.05.132 in October). Earlier lines (25.11, 25.04) got maintenance releases into December 2025. No entry describes actual changes.

◆ Where it's heading

The pattern is roughly two feature lines a year, then frontend-only builds and backported maintenance. The direction of the product can't be read from version numbers alone.

◆ Prediction

Another 26.05 frontend build in the next one to two months fits the cadence; the next major line's timing and content are unclear from the entries.
