DebugBear vs OpenPanel: at a glance
What is DebugBear?
DebugBear is growing out of performance testing into availability, agents, and dashboards you build yourself.
Six monthly digests show a tool widening on three fronts. Availability arrived in August with uptime monitoring, alongside Server Timing support across both lab tests and real-user monitoring and URL-based conversion triggers. Analysis tooling deepened with a bottleneck finder, HAR waterfall exports, individual chart exports, histogram and scatter charts, and custom dashboards as a first-class feature in April. And the product started addressing AI clients directly: a DebugBear MCP server for Claude, ChatGPT, and Cursor in June, preceded by a Lighthouse category for agentic browsing and prepared AI agent prompts in May.
What is OpenPanel?
OpenPanel ships 3.1.0 and 3.1.1 within a day of 3.0, all supporter-first builds with no notes.
OpenPanel's self-hosted line went from 3.0.0 to 3.1.1 in under a day on October 16-17. Each is a build of main delivered to supporters through openpanel upgrade --supporter, with public releases following from the self-hosting tag. None of the three builds carries release notes. Before them came the supporter preview of the rewritten v2 self-hosting CLI and a fix keeping saved reports' filters and cohort ids.

DebugBear is growing out of performance testing into availability, agents, and dashboards you build yourself.
◆ Current state
Six monthly digests show a tool widening on three fronts. Availability arrived in August with uptime monitoring, alongside Server Timing support across both lab tests and real-user monitoring and URL-based conversion triggers. Analysis tooling deepened with a bottleneck finder, HAR waterfall exports, individual chart exports, histogram and scatter charts, and custom dashboards as a first-class feature in April. And the product started addressing AI clients directly: a DebugBear MCP server for Claude, ChatGPT, and Cursor in June, preceded by a Lighthouse category for agentic browsing and prepared AI agent prompts in May.
◆ Where it's heading
Two expansions are running at once. The first is scope — a synthetic and RUM performance tool adding uptime monitoring competes for the budget line that currently goes to a separate availability vendor, and conversion triggers push the same data toward business rather than engineering reporting. The second is who consumes the data: an MCP server means an agent pulls DebugBear results into an investigation without a human opening the dashboard, while the agentic browsing audit measures whether a site works for those agents at all. Custom dashboards sit underneath both, letting teams assemble their own views instead of accepting the built-in ones.
◆ Prediction
Expect uptime monitoring to acquire the alerting and status-reporting depth that makes it replace an incumbent rather than supplement one, since a monitor without mature alerting is only half the purchase. The digests are short enough that how the MCP server is being used is not yet visible.
OpenPanel
5.0ANALYTICS
OpenPanel ships 3.1.0 and 3.1.1 within a day of 3.0, all supporter-first builds with no notes.
◆ Current state
OpenPanel's self-hosted line went from 3.0.0 to 3.1.1 in under a day on October 16-17. Each is a build of main delivered to supporters through openpanel upgrade --supporter, with public releases following from the self-hosting tag. None of the three builds carries release notes. Before them came the supporter preview of the rewritten v2 self-hosting CLI and a fix keeping saved reports' filters and cohort ids.
◆ Where it's heading
The visible pattern is a fast post-3.0 release train on the self-hosted path, with the new CLI's upgrade command as the delivery channel and paying supporters as the early ring. Two minor bumps right after a major suggest follow-up fixes or small additions on top of 3.0. What 3.x changes for analytics users is still not documented in the entries.
◆ Prediction
Expect more 3.1.x builds and a public 3.x release through the self-hosting tag. Without release notes, it's unclear whether the 3.x line adds analytics features or mainly reworks self-hosting infrastructure.
