The Sitebulb alternative built to monitor, not just audit

Spronta vs Sitebulb at a glance

Is Spronta a good Sitebulb alternative?

Yes, if what you actually want is to know when something breaks — not just how the site looked the day you ran an audit. Spronta runs the same core technical checks, then keeps running them: on a schedule, on every deploy, with findings tracked as issues that carry priority and lifecycle across crawls, and alerts when a score regresses. Sitebulb still leads if your deliverable is the audit document itself.

What does Spronta do that Sitebulb doesn't?

Treat findings as issues rather than report rows. A problem gets an ID, a priority and an assignee; it persists across crawls, gets flagged when it worsens, and is verified closed when a crawl confirms the fix. Add deploy-triggered crawls with the commit attached, regression alerts where your team talks, GEO scoring for AI search, and a hosted MCP endpoint so agents can run the whole loop.

When is Sitebulb still the better choice?

When the audit is the product. Consultants who hand clients a beautifully structured document — with visual crawl maps and deeply explained hints — will still love Sitebulb. Spronta's reports are built to be worked from, not printed: an inbox your team burns down, not a PDF. If you need both, they coexist fine.

Where Sitebulb is still the better choice

No tool wins on everything — here's where Sitebulb currently leads, so you can choose with eyes open:

• Visual crawl maps and force-directed link graphs — Sitebulb's signature, and still the best way to see site architecture at a glance.
• A deep, well-curated Hint library with detailed explanations — genuinely great audit education.
• Polished audit documents for client deliverables, with per-user desktop licences that are cheap for a solo consultant.

Frequently asked questions

Does Spronta replace Sitebulb?

For monitoring, yes: scheduled and deploy-triggered crawls, a durable issue inbox, and regression alerts are the always-on loop Sitebulb isn't built around. For one-off audit documents with visual crawl maps, Sitebulb is still excellent.

How much does Spronta cost?

Free tier: 5,000 crawl credits a month, no card. Paid plans from $19/month, priced by pages crawled — seats are unlimited on every plan. Sitebulb licences start around £13.50/month per user, with Sitebulb Cloud priced separately.

Does Spronta compare two crawls like Sitebulb?

Yes — diff any two crawls to see score deltas, pages added and removed, and issues fixed vs newly appeared. Because findings are durable issues, Spronta also tracks lifecycle automatically: new, worsening, regressed, resolved.

Does Spronta render JavaScript?

Yes. Pages render in headless Chrome in the cloud, and Spronta diffs rendered vs raw HTML so you can see exactly what JavaScript changes — titles, canonicals, content that only exists client-side.

Does Spronta have Sitebulb's visual crawl maps?

No. Spronta surfaces the same underlying data — depth, inlinks, orphans — as sortable tables and per-page detail rather than force-directed diagrams. If crawl maps are core to your deliverable, that's a real Sitebulb advantage.
