But it has no public API and no MCP server yet (one is in the works), which means if your workflow depends on scheduled crawls, programmatic triggers, or connecting an AI agent to your crawl data, you're stuck routing through Zapier or Make instead of a direct connection.
Why Switch
Why people look for Sitebulb alternatives
No public API documented, which blocks scheduled or programmatic crawls without third-party tools like Zapier
No MCP server live yet, so AI assistants can't query your crawl data directly (a waitlist exists, but it's not shipped)
Sitebulb is a dedicated crawler, not a full SEO suite. If you need keyword research or backlink data too, you'll be paying for a second tool anyway
Real-time collaboration across a team only comes with Sitebulb Cloud, which is a separate step up from Desktop
If you're already running Ahrefs, Semrush, or SE Ranking for other SEO work, their built-in site audit modules might make a standalone crawler redundant
Alternatives
Best Sitebulb alternatives
8 alternatives ranked. 2 are cheaper. 14 offer free plans.
Screaming Frog
Freelancers and solo SEOs who want a proven desktop crawler at a fixed, low price
Desktop SEO crawler for technical audits with unlimited crawling for $259/year
Why consider Screaming Frog
Screaming Frog is the closest like-for-like comparison to Sitebulb. Both are desktop crawlers built for the same job, but Screaming Frog runs $259/year for the paid version and has a free tier to start with.
Pros
- +Straightforward annual pricing with unlimited crawling on the paid tier
- +Has both a documented API and an MCP server, so it's ahead of Sitebulb on AI-agent connectivity
- +Long track record, widely used across agencies
Cons
- −Interface is more data-table, less visual than Sitebulb's Hints and dashboards
- −Free version caps crawl volume, so serious use requires the paid license
Semrush
Teams that want site audits bundled with keyword research and competitor tracking
Complete SEO platform with AI search tracking, keyword research, competitor analysis, and content optimization tools
Why consider Semrush
Semrush folds a crawler into a much bigger SEO and AI-search tracking platform, so you're not paying for a standalone tool if you already need keyword and competitor data.
Pros
- +One subscription covers site audits, keyword research, and AI search tracking
- +Has a Semrush MCP server, giving it native AI-assistant connectivity Sitebulb doesn't have yet
- +7-day trial to test before committing
Cons
- −Exact plan pricing wasn't listed in my research, so check the Semrush pricing page for current rates
- −Site audit module is one piece of a much larger, more complex platform, which can feel like overkill if all you need is crawling
Ahrefs
SEOs who want a crawler plus the deepest backlink dataset on the market
Broad SEO platform with powerful backlink analysis and keyword research tools
Why consider Ahrefs
Ahrefs pairs a competent site audit tool with backlink analysis that's hard to match, starting at $29/month for the Starter plan and free tools to try first.
Pros
- +Backlink analysis is a genuine strength beyond just crawling
- +Has an Ahrefs MCP server and documented API for automation
- +Free plan available before you commit to a paid tier
Cons
- −Pricing climbs fast: Lite is $129/mo, Standard $249/mo, Advanced $449/mo
- −Site audit is a module inside a bigger suite, not a dedicated crawler experience
Lumar (formerly Deepcrawl)
Enterprise teams needing AI search visibility tracking alongside technical audits
Website optimization platform for AI visibility, technical SEO, site speed, accessibility, and custom analytics built for enterprise teams.
Why consider Lumar (formerly Deepcrawl)
Lumar (formerly Deepcrawl) goes further than Sitebulb into AI visibility (GEO/AEO) tracking and brand mention monitoring, on top of 500+ built-in technical SEO reports.
Pros
- +AI search visibility and brand mention tracking, which Sitebulb doesn't offer at all
- +Core Web Vitals and WCAG 2.2 accessibility testing built in
- +CI/CD pipeline integration for automated site QA, and a Lumar MCP server for AI-agent access
Cons
- −Contact sales only, no public pricing to compare against Sitebulb's tiers
- −Built for enterprise scale, likely more tool than a freelancer or small agency needs
SE Ranking
Agencies wanting audits, rank tracking, and content optimization in one toolkit
Strong SEO toolkit combining site auditing, keyword research, rank tracking, and content optimization for agencies and in-house teams
Why consider SE Ranking
SE Ranking bundles a site auditor with keyword tracking and content tools at $129/month for the Core plan, with a 14-day trial to test the fit.
Pros
- +Combines audit, rank tracking, and content optimization instead of just crawling
- +Has an SE Ranking MCP server, so agents can query data directly
- +14-day trial gives more runway than most competitors' free trials
Cons
- −Growth plan jumps to $279/mo, a steep step up from Core
- −Not a dedicated crawler, so depth on JavaScript rendering and crawl customization may not match Sitebulb
Moz
Teams that want a familiar, established platform with a simple learning curve
Veteran SEO platform with 20+ years of experience offering site audits, rank tracking, and broad toolkit for optimization
Why consider Moz
Moz has been around for 20+ years and offers site audits alongside rank tracking, appealing to teams who want stability over bleeding-edge features.
Pros
- +Long-established platform with a large support and community footprint
- +Combines audits with rank tracking in one dashboard
- +Has a documented Moz Pro API for programmatic access
Cons
- −Exact pricing wasn't available in my research; check the Moz pricing page directly
- −No MCP server, so AI-agent access is limited to whatever the API allows
Seobility
Beginners or budget-conscious users who want a free tier to start
User-friendly SEO platform with website auditing, keyword tracking, and backlink analysis for all skill levels
Why consider Seobility
Seobility offers a genuinely free Basic tier alongside paid plans starting at €49.90/month , making it one of the more accessible options on this list.
Pros
- +Free plan exists, unlike Sitebulb which only offers a free trial
- +Premium at €49.90/mo and Agency at €179.90/mo give room to scale as needs grow
- +Has a documented Seobility API
Cons
- −Less depth on advanced technical checks compared to Sitebulb's 300+ Hints
- −No MCP server for direct AI-assistant queries
Crawly
Solo SEOs and Mac users who want a free desktop crawler that plugs straight into AI agents
Free native macOS SEO crawler with a built-in MCP server (Windows and Linux coming soon)
Why consider Crawly
Crawly is the free, Mac-native answer to Sitebulb's desktop mode. You get real technical crawling at no cost, and it ships with a built-in MCP server , so Claude and other agents can query your crawl data directly. That is something Sitebulb only has on its roadmap.
Pros
- +Completely free, with unlimited local crawling on macOS
- +Built-in MCP server so AI agents can query your crawl data directly, ahead of Sitebulb on that front
- +Native Mac app: lightweight, fast, and your crawl data stays on your machine
Cons
- −macOS only for now (Windows and Linux are on the roadmap), so PC users are out for the moment
- −Newer and lighter than Sitebulb: fewer Hints, no cloud tier, and less depth for very large or team crawls

Checklist
What to look for in an alternative
Start with crawl scale. Sitebulb Desktop handles up to 500,000 URLs per audit and Cloud pushes that to 10 million, so figure out whether your sites (or your clients' sites) actually need that ceiling before you pay for it. Then think about how the tool fits your stack.
If you or your team want to automate reporting, trigger crawls on a schedule, or hand data to an AI agent, check whether the tool has a documented API or an MCP server, not just a Zapier integration bolted on the side.
This is exactly where what makes software good in 2026 differs from 2020: connectivity matters as much as the crawl engine itself. Last, be honest about whether you need a pure crawler or a full platform.
A dedicated crawler gives you deeper technical checks and JavaScript rendering without extra cost, but a suite like Semrush or Ahrefs bundles keyword tracking and backlink data in, which can work out cheaper than running two subscriptions.

FAQ
Frequently Asked Questions
Both are desktop SEO crawlers built for technical audits. Screaming Frog runs $259/year with unlimited crawling on the paid tier and has both a documented API and an MCP server, while Sitebulb leans harder on visual data presentation, prioritized Hints, and in-built education, but has no public API or MCP server yet.
Sitebulb has no documented public API, which rules out scheduled or programmatic crawls without a third-party tool like Zapier or Make. An MCP server is listed as coming soon on Sitebulb's site, with a waitlist open, but it isn't live yet.
Seobility has a free Basic tier, and Screaming Frog's paid plan runs $259/year. Ahrefs starts at $29/month for its Starter plan if you mainly want backlink data alongside crawling.
Sitebulb Cloud can crawl up to 10 million URLs per audit with no project limits and real-time team collaboration, which covers most enterprise needs. For AI search visibility tracking at enterprise scale specifically, Lumar goes further with dedicated GEO/AEO brand mention monitoring.
Crawly ships with a built-in MCP server, so AI agents can query its crawl data out of the box. Screaming Frog and Ahrefs also expose official MCP servers. Sitebulb's own MCP is still on the waitlist (coming soon), so it is not available yet.
Yes, but only with Sitebulb Cloud. Sitebulb Desktop is a local application, so real-time team collaboration on the same crawl data requires stepping up to the Cloud plan.
It depends on what else you need. If technical crawling is your only requirement, a dedicated tool like Screaming Frog keeps costs lower and focused. If you also need keyword research, backlink data, or AI search visibility tracking, a suite like Semrush, Ahrefs, or SE Ranking can replace multiple subscriptions with one.
