DebugBear vs Treo in 2026: Self-instrumented RUM vs free Chrome UX Report data
DebugBear captures real-user data from your own visitor sessions starting at $68 a month. Treo pulls from Google's public CrUX dataset with a permanent free tier for a single site.
DebugBear
Treo- Treo has a permanent free tier covering one site with CrUX field data. DebugBear has no free tier at any level, only a 14-day trial.
- DebugBear's real-user monitoring comes from your own instrumented visitor sessions and requires the Pro plan (~$149/month). Treo's Core Web Vitals data comes from Google's public CrUX dataset and is included even on the free tier.
- Treo automatically discovers URLs to monitor by scanning a site's sitemap. DebugBear does not document an equivalent automated discovery feature.
- DebugBear includes unlimited domains on every paid plan. Treo caps sites per tier: 1 on Free, up to 5 on Vital, up to 15 on Pro, and up to 50 on Scale.
- DebugBear tracks four Lighthouse categories, Performance, Accessibility, Best Practices, and SEO, over time. Treo's Lighthouse audits are limited on its free tier and run hourly on paid plans, focused primarily on Core Web Vitals rather than the full Lighthouse category set.
- Treo offers competitive Core Web Vitals benchmarking against competitor domains from its Vital plan at $75/month. DebugBear has no competitive benchmarking feature.
DebugBear and Treo both track Core Web Vitals, but they get their real-user data from different places, and that difference shapes everything else about how each tool is priced and used. DebugBear instruments your own site to capture RUM from actual visitor sessions, which requires the Pro plan and means you are paying for infrastructure that generates fresh data regardless of traffic volume. Treo reads from the Chrome UX Report (CrUX), Google's public 28-day rolling dataset of real Chrome user experience, which is free to query and requires no script installation, but only covers pages with enough Chrome traffic to appear in the dataset at all. Treo also automatically discovers URLs from a sitemap, where DebugBear expects you to configure what gets monitored.
The tools at a glance
DebugBear
Web performance monitoring that combines real-user data, synthetic testing, and Lighthouse score tracking to catch regressions before they affect rankings.
DebugBear builds its Core Web Vitals picture from real-user monitoring on your own site, combined with scheduled synthetic tests and Lighthouse score tracking across four categories: Performance, Accessibility, Best Practices, and SEO. Because RUM is instrumented directly rather than pulled from a public dataset, it captures data from every visitor session, not just the ones that clear Chrome's traffic threshold for inclusion in CrUX.
Unlimited domains ship on every paid plan, which is a meaningful difference from Treo's per-site tier caps for agencies managing a growing client list. The Looker Studio connector turns monitoring data into client dashboards without custom development.
The cost of that instrumented approach is that there is no free tier, and RUM itself sits behind the Pro plan at roughly $149/month. There is also no automated URL discovery; sites and pages need to be configured rather than found automatically from a sitemap, and DebugBear has no competitive benchmarking feature to compare against other domains.

Treo
Core Web Vitals monitoring using real-world Chrome UX Report data.
Treo is built specifically around Core Web Vitals, pulling field data from the Chrome UX Report rather than requiring you to instrument your own RUM collection. That data reflects how real Chrome users experienced a page over the trailing 28 days, so lab scores that look fine can be checked against what the CrUX dataset says actually happened for real visitors, at no monitoring cost on the free tier.
Point Treo at a domain and it reads the sitemap to discover URLs automatically, removing the manual setup most monitoring tools require. Competitive benchmarking lets you track a competitor's Core Web Vitals scores alongside your own from the Vital plan upward, and the API lets you pull data into your own reporting pipelines or Looker Studio dashboards.
The trade-off is coverage and pricing shape. CrUX only includes URLs with enough real-user Chrome traffic, so new or low-traffic pages may show no field data at all, only Lighthouse lab scores. And while the Free tier covers one site at no cost, the jump to Vital at $75/month for up to five sites is steep for what is fundamentally a monitoring layer on public data.
| Feature | Free $0/month | Vital $75/month | Pro $185/month | Scale $375/month | Enterprise Contact for pricing |
|---|---|---|---|---|---|
| Sites monitored | 1 | Up to 5 | Up to 15 | Up to 50 | Custom |
| CrUX field data | Yes | Yes | Yes | Yes | Yes |
| Competitive benchmarking | No | Yes | Yes | Yes | Yes |
| API access | No | Yes | Yes | Yes | Yes |

Which should you choose?
TreoDebugBearDebugBearTreoTreoDebugBearThese tools start from different data philosophies. Treo leans on Google's public CrUX dataset, which is free, requires no instrumentation, and reflects genuinely real Chrome users, but only for pages with enough traffic to clear CrUX's inclusion threshold. DebugBear instruments RUM directly, so it captures every visitor session and every page regardless of traffic volume, plus a fuller Lighthouse category set beyond just Core Web Vitals, but charges for that at every tier with no permanent free option.
Bottom line
Start with Treo's free tier if you are validating whether CrUX coverage is good enough for your site's traffic level and want automated sitemap discovery with zero setup cost. Move to DebugBear once you are managing multiple domains, need RUM data on low-traffic or new pages that CrUX does not cover, or want the full Lighthouse category breakdown alongside performance. Agencies with a large client roster will likely find DebugBear's unlimited domains more economical than Treo's per-tier site caps once past a handful of sites.
Frequently asked questions
What is the real difference between Treo's CrUX data and DebugBear's real-user monitoring?
Treo reads from Google's Chrome UX Report, a public 28-day rolling dataset of real Chrome user experience that requires no script installation but only covers pages with enough Chrome traffic to be included. DebugBear instruments your own site directly, so it captures RUM from every visitor session regardless of traffic volume, but that requires the Pro plan at roughly $149/month.
Does Treo have a free tier and does DebugBear have one too?
Treo has a permanent free tier covering one site with CrUX field data included. DebugBear does not offer a free tier at any level; it only provides a 14-day trial with no credit card required before you need to choose a paid plan.
Which tool is better for a site with low traffic or newly published pages?
DebugBear is the better fit here, since its RUM is instrumented directly on your own site and captures data regardless of traffic volume. Treo's CrUX-based data only covers URLs with sufficient real-user Chrome traffic, so new or low-traffic pages may show no field data at all, just Lighthouse lab scores.
Can I track a competitor's Core Web Vitals with either tool?
Treo supports this from its Vital plan at $75/month, tracking competitor domains' Core Web Vitals scores using the same CrUX data source as your own site. DebugBear does not have a competitive benchmarking feature at any tier.
Is Treo's automated sitemap scanning better than manually configuring URLs in DebugBear?
For large sites, Treo's automated sitemap scanning saves real setup time since it discovers URLs with no tagging or manual list maintenance required. DebugBear does not document an equivalent automated discovery feature, so sites and pages need to be configured directly, which is more control but more upfront work.
Which tool is cheaper for an agency monitoring 10 or more client sites?
DebugBear is likely cheaper at that scale, since unlimited domains are included on every paid plan starting around $68/month. Treo caps sites per tier, up to 15 sites on its $185/month Pro plan, so an agency past that threshold would need the $375/month Scale plan or higher just to cover site count, independent of feature needs.
