Sitebulb vs Treo in 2026: Full-site technical crawler vs Core Web Vitals monitoring
Sitebulb crawls a whole site for 300+ prioritized SEO hints starting at $18 a month. Treo skips crawling entirely and monitors Core Web Vitals through real Chrome UX Report data, with a genuine free tier.
Sitebulb
Treo- Sitebulb crawls an entire site for 300+ prioritized technical SEO hints; Treo does not crawl for technical issues at all, it only monitors Core Web Vitals field and lab data.
- Treo has a genuine free tier covering one site; Sitebulb has no permanent free option, only a 14-day trial on paid plans starting at $18/month.
- JavaScript rendering is included on every Sitebulb plan at no extra cost, including the $18/month Lite tier.
- Treo pulls real Chrome UX Report (CrUX) field data alongside on-demand Lighthouse lab scores; Sitebulb has no performance monitoring or Core Web Vitals feature of any kind.
- Sitebulb Cloud scales to 10 million URLs per audit; Treo prices by number of sites monitored, capping at 50 sites on the $375/month Scale plan before Enterprise.
- Treo documents API access from its $75/month Vital plan up; Sitebulb does not publicly document an API at any tier.
- Sitebulb has an MCP server for AI-assisted audit querying in development, currently on a waitlist; Treo has announced no equivalent AI tooling.
Sitebulb and Treo both live under the technical SEO umbrella, but they are built to answer different questions. Sitebulb crawls a site end to end and returns over 300 prioritized hints on broken links, duplicate content, redirect chains, and dozens of other structural issues, with JavaScript rendering included on every plan from $18 a month. Treo does not crawl for technical issues at all. It pulls real-world Core Web Vitals data from the Chrome UX Report, layers on-demand Lighthouse scores on top, and discovers URLs automatically through sitemap scanning, with a free tier for a single site. If the job is finding what is structurally wrong with a site, Sitebulb does that. If the job is proving how fast real visitors experience the pages that are already live, Treo is built for exactly that and nothing else.
The tools at a glance
Sitebulb
Website crawler for technical SEO audits with prioritized hints and visual reporting
Sitebulb crawls a site and turns the raw output into more than 300 prioritized Hints, each ranked by severity with educational context attached, so the output reads as a to-do list rather than a spreadsheet dump. JavaScript rendering ships on every plan including the $18/month Lite tier, which is unusual: several competing crawlers charge separately for rendered crawls or gate them behind an enterprise upgrade.
The product splits into Desktop, which runs locally and tops out at 500,000 URLs per audit on Pro, and Cloud, which adds scheduled recurring crawls, team collaboration, and capacity up to 10 million URLs starting at $125/month. Reporting is a real strength here: Pro and Cloud plans generate branded PDF exports and feed data visualizations that make presenting technical findings to a non-technical client noticeably easier than handing over a raw CSV.
What Sitebulb does not do is measure page speed. There is no Core Web Vitals tracking, no field data, and no waterfall diagnostics anywhere in the product; it is scoped to finding and prioritizing structural and content issues across a crawl, not to monitoring how fast a page loads for real visitors over time.

|---|---|---|---|
| URLs per audit | 10,000 | 500,000 | Up to 10 million |
| SEO Hints | 100+ | 300+ | 300+ |
| JavaScript crawling | Yes | Yes | Yes |

| Customized PDF reports | No | Yes | Yes |
| Free trial | 14 days | 14 days | 14 days |
Treo
Core Web Vitals monitoring using real-world Chrome UX Report data.
Treo builds its entire product around one idea: synthetic Lighthouse scores can look fine while real users are still stuck with slow LCP or layout shift. It solves that by pulling field data straight from the Chrome UX Report, which reflects how actual Chrome users experienced a page over the past 28 days, and pairing it with on-demand Lighthouse audits so a lab score and a real-world score sit next to each other.
Setup is close to zero effort compared to a crawler: point Treo at a domain and it reads the sitemap to discover URLs automatically, with no tagging script and no manual URL list to maintain. Paid plans add competitive benchmarking against named domains, a multi-site dashboard for tracking client portfolios, and API access for pulling data into Looker Studio or a custom reporting pipeline.
The free tier covers exactly one site, which is enough to sample the data quality but not to run an agency workflow. Competitive benchmarking and API access only unlock on the $75/month Vital plan, and that plan caps at five sites, so a larger agency portfolio needs Pro or Scale for real headroom. Treo has no crawling, no hint system, and no technical issue detection beyond performance; that is the whole trade for the CrUX-first focus.
| 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?
SitebulbTreoSitebulbTreoSitebulbTreoSitebulbThese two tools barely compete, they sit on different layers of the same technical SEO stack. Sitebulb answers "what is structurally broken on this site," with a crawl, a severity-ranked hint list, and reporting built for handing off to a client. Treo answers "how fast is this site for the people actually using it," using field data Sitebulb does not collect at all. A site with an unmanaged crawl backlog and no performance visibility needs both, not one instead of the other.
Bottom line
Start with Sitebulb's 14-day trial on the Pro plan if the immediate need is finding and prioritizing structural technical SEO issues across a site, since there is no permanent free tier to fall back on. Start on Treo's free tier if the immediate need is Core Web Vitals visibility for a single site, and move to the $75/month Vital plan once competitive benchmarking or API access becomes necessary. Neither tool substitutes for the other: Sitebulb will not tell you how fast your pages load for real users, and Treo will not tell you why a page is throwing a 404 or missing its meta description.
Frequently asked questions
Do Sitebulb and Treo do the same job?
No, they cover different parts of technical SEO. Sitebulb crawls a full site and returns 300+ prioritized hints on structural issues like broken links and duplicate content, while Treo monitors Core Web Vitals using real Chrome UX Report field data and does no crawling or issue detection at all.
Is Treo free to use, unlike Sitebulb?
Yes, Treo has a genuine free tier covering one site with CrUX field data and automated sitemap discovery, no credit card required. Sitebulb has no permanent free plan, only a 14-day trial on its paid tiers starting at $18/month.
Can Sitebulb monitor Core Web Vitals the way Treo does?
No, Sitebulb has no Core Web Vitals or performance monitoring feature in its product. Its scope is crawling a site and surfacing prioritized technical SEO hints; a dedicated tool like Treo is needed for real-user performance data.
Which tool is better for an agency managing dozens of client sites?
It depends on which problem the agency is solving. Sitebulb Cloud scales to 10 million URLs per audit and adds team collaboration and scheduled crawls for technical audits, while Treo's multi-site dashboard and competitive benchmarking are built specifically for tracking Core Web Vitals across a client portfolio.
Does Sitebulb have an API like Treo?
Sitebulb does not publicly document an API at any pricing tier. Treo documents API access from its $75/month Vital plan up, letting teams pull performance data into Looker Studio or a custom reporting pipeline.
Which tool should I pick if I only care about page speed, not full technical audits?
Treo is the better fit for page speed specifically, since it is built entirely around Core Web Vitals and Chrome UX Report data with a free starting tier. Sitebulb has no page speed testing at all, so paying for it to solve a performance problem would be paying for the wrong tool.
