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 Keila?
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.
Gumloop vs Keila: 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.
Keila
2.5MKT AUTO
Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.
◆ Current state
Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.
◆ Where it's heading
Keila's recent releases — v0.30.0's transactional email API, v0.20.0's new email scheduler, and now v0.30.3's performance work — show a project that is consolidating its architecture before broadening its feature set. The self-hosting focus remains; the additions to system mailer configurability suggest the project is listening to operators running Keila in production with non-standard SMTP setups.
◆ Prediction
Transactional email capabilities from v0.30.0 will likely expand — more API endpoints, webhook delivery events, or better unsubscribe handling for transactional vs. campaign messages. Performance tooling for large lists will continue as the Liquid caching work surfaces the right optimization targets.
