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 MailBeez?
MailBeez hardens its big 'V5' rewrite with PHP 8.x compatibility and up-to-10x page-load gains.
MailBeez is a ZenCart email-marketing plugin midway through a major 'V5' platform modernization — redesigned navigation, a marketing calendar, and new flow, audience, and product-review tooling. The recent releases are the stabilization tail of that push: point releases hardening PHP 7.4-to-8.6 compatibility, ZenCart 2.2.2 support, and large page-load gains. That sweep has now reached the addon catalogue, with individual modules refactored for PHP 8 one at a time.
Gumloop vs MailBeez: 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.
MailBeez
5.0MKT AUTO
MailBeez hardens its big 'V5' rewrite with PHP 8.x compatibility and up-to-10x page-load gains.
◆ Current state
MailBeez is a ZenCart email-marketing plugin midway through a major 'V5' platform modernization — redesigned navigation, a marketing calendar, and new flow, audience, and product-review tooling. The recent releases are the stabilization tail of that push: point releases hardening PHP 7.4-to-8.6 compatibility, ZenCart 2.2.2 support, and large page-load gains. That sweep has now reached the addon catalogue, with individual modules refactored for PHP 8 one at a time.
◆ Where it's heading
The throughline is the V5 rewrite moving from feature delivery into consolidation. After landing the redesigned UI and new marketing tooling in spring, the cadence shifted to compatibility and performance hardening — isolating Smarty loading, migrating PHP versions, and cutting page-load times. The August entry shows that work reaching the long tail of small integration addons, which is usually the last stage of such a migration.
◆ Prediction
Expect the addon-by-addon PHP 8 sweep to continue until the catalogue is covered, alongside V5 stabilization point releases. The entries give no signal on when remaining legacy flows finish migrating.
