CoreDash vs DebugBear (2026): which should you pick?

Pick CoreDash if

• Fits if you need to know which element or script is causing a poor Core Web Vital
• Works for EU sites that want RUM without cookies or a consent banner

Look elsewhere if

• Skip it if you want a free plan, as there's only a 14-day trial
• Pricey if you want AI insights, the MCP server or the API, which start at Standard, $31 a month billed yearly
• Tight if you run several sites, as Starter covers 1 and Standard up to 2
• Watch out: extra pageview blocks (about $5 to $25 each) and site slots ($0.50 to $2 each) are monthly add-ons
• Not for you if you want lab tests too, as it measures real visits only

Pick DebugBear if

• Fits if you need lab, real-user and CrUX speed data for a site in one account
• Works for developers who want slow-page fixes as prompts for Claude Code or Cursor

Look elsewhere if

• Pricey if you have one small site, at $99 a month on yearly billing with no free plan
• Tight if you run several sites, as Startup covers 1 project and Team at $249 has 5
• Watch out: extra real-user page views, tests and projects are added for an extra monthly fee
• Not for you if you need SSO or invoice payment, which are Enterprise only at a custom price

CoreDash

Real-user Core Web Vitals

Measures LCP, INP, CLS, TTFB and FCP on every pageview with Google's web-vitals library, unsampled and with no limit on tracked URLs.

Attribution and waterfalls

Each slow pageview carries a request waterfall and names the LCP element, the interaction behind a poor INP or the shifting element, plus long animation frame scripts.

Segmentation

Filter by device, browser, OS, country, network speed, page group, navigation type and custom labels such as A/B variant or login state.

Alerts and uptime

Pulse alerts by email or Slack when a metric slips, and uptime monitoring that reports when a site or checkout stops responding.

AI insights and MCP server

From the Standard plan, an MCP server lets Claude, Cursor or another AI agent read your live performance data, alongside built-in AI insights.

CI/CD checks

One curl call from a build pipeline flags deploys that miss performance budgets and tracks real-user results per release.

DebugBear

Synthetic monitoring

Scheduled and on-demand Lighthouse lab tests from test locations around the world, including pages behind a login and multi-step user flows.

Real user monitoring

Measures Core Web Vitals for real visitors and shows which page elements and scripts cause slow interactions that hurt INP.

Google CrUX data

Tracks Chrome User Experience Report data over time and compares your site's real-visitor speed with competitors.

Waterfalls and recommendations

Request waterfalls tied to CPU and rendering activity, automatic fix suggestions, and ready-made prompts for coding agents such as Claude Code or Cursor.

Page speed experiments

Try an optimization on a test run to see its effect before deploying the change to the live site.

Alerts, comparisons and exports

Automatic alerts on regressions, before-and-after comparisons, chart annotations, video exports and PDF or CSV reports. Data is kept for 24 months.
