What is Countly?
Countly 25.03.59 defaults to Node 26, supports MongoDB 9 and tightens app scoping.
Countly 25.03.59 on November 13 is a large LTS patch. Clean installs and Docker images move to Node.js 26 and MongoDB 9.0, with older versions still working, and arm64 Docker images arrive. Security fixes tighten which apps a scoped token or member can reach across exports, dashboards, alerts and data tools, and wrong two-factor codes now count toward lockout.
What is Marker.io?
Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.
Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.

Countly
5.0ANALYTICS
Countly 25.03.59 defaults to Node 26, supports MongoDB 9 and tightens app scoping.
◆ Current state
Countly 25.03.59 on November 13 is a large LTS patch. Clean installs and Docker images move to Node.js 26 and MongoDB 9.0, with older versions still working, and arm64 Docker images arrive. Security fixes tighten which apps a scoped token or member can reach across exports, dashboards, alerts and data tools, and wrong two-factor codes now count toward lockout.
◆ Where it's heading
Countly is still mostly hardening access control, carrying the token-scoping work from 25.03.58 into every plugin that reads or changes app data. At the same time it keeps the self-hosted stack on current runtimes.
◆ Prediction
Expect a 24.05 patch that backports these scoping fixes, as 24.05.55 did after 25.03.58.
Marker.io
3.8ANALYTICS
Marker.io stops waiting for bug reports and starts scanning sites for accessibility issues.
◆ Current state
Marker.io began as a widget for reporting website bugs and spent the past year adding AI to every step: translation, rewriting, title generation and an MCP server that lets coding agents fix issues from a Marker URL. In late October it launched Website Monitoring, which scans chosen pages on a schedule with 90 WCAG 2.2 AA accessibility checks and turns failures into issues.
◆ Where it's heading
The product is moving from collecting problems people report to finding problems on its own, and then handing them to coding agents through MCP. Accessibility is the first monitoring check, and the release title says it is only the start. Workflow statuses and analytics fill in the team side.
◆ Prediction
Expect more monitoring checks beyond accessibility, since the release frames accessibility as the first. How monitoring is priced is not clear from the entries.
