What is Gumloop?
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
Gumloop ships a numbered release every few days, and since 12.0's Agent Browser each one widens what agents can reach and govern. 12.4 lets the Gumball agent use several accounts for the same app, share artifacts, skills and agents across teams, and set up custom MCPs for apps without a native connector. It also adds per-model spend and BYOK savings reporting in Insights, plus email search in audit logs, after 12.3's model-gated triggers and new frontier models.
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.
Gumloop vs Hello Bar: editorial side-by-side
Gumloop
6.3MKT AUTO
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
◆ Current state
Gumloop ships a numbered release every few days, and since 12.0's Agent Browser each one widens what agents can reach and govern. 12.4 lets the Gumball agent use several accounts for the same app, share artifacts, skills and agents across teams, and set up custom MCPs for apps without a native connector. It also adds per-model spend and BYOK savings reporting in Insights, plus email search in audit logs, after 12.3's model-gated triggers and new frontier models.
◆ Where it's heading
The platform is moving from workflow automation to a managed agent runtime: agents browse, own credentials, manage files and skills, and now extend their own integrations through custom MCPs. Cross-team sharing and spend reporting point at larger organizations, with credit cost kept a visible part of the product.
◆ Prediction
Expect more organization-level controls for shared agents and custom MCPs, such as approvals or admin policies, given the new sharing and audit-log search. The entries don't show pricing changes for agent-built integrations.
Hello Bar
2.5MKT AUTO
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.
