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 OpenCTI?

OpenCTI's assistant starts executing approved tools, and its maps stop calling out.

OpenCTI is an open-source threat-intelligence platform shipping several times a week. 7.260828.0 adds human-in-the-loop tool approval to Ask Ariane, the platform's assistant, replaces the external map tile server with local PMTiles rendering, and adds two inference rules deriving vulnerability relationships across systems, software and infrastructure. A Score field arrives on threat actors, intrusion sets, malware, incidents and events.

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.

6.3

OpenCTI's assistant starts executing approved tools, and its maps stop calling out.

◆ Current state

OpenCTI is an open-source threat-intelligence platform shipping several times a week. 7.260828.0 adds human-in-the-loop tool approval to Ask Ariane, the platform's assistant, replaces the external map tile server with local PMTiles rendering, and adds two inference rules deriving vulnerability relationships across systems, software and infrastructure. A Score field arrives on threat actors, intrusion sets, malware, incidents and events.

◆ Where it's heading

Recent releases have been steady platform work: shareable saved searches, mass relation edits, STIX ingestion robustness, an LTS security backport. Two moves here break that pattern — the assistant shifting from answering to acting under approval, and an external dependency disappearing from the map path. The inference rules continue OpenCTI's push to derive relationships rather than make analysts assert them by hand.

◆ Prediction

Expect the next releases to spell out which tools Ask Ariane may call and under which roles, since the approval mechanism arrives here as a single changelog line with no scope attached.
