Sitebulb alternatives: 8 open-source picks
Sitebulb costs $18/mo — $216 a year. These 8 alternatives replace it for $0, led by SiteOne Crawler, LibreCrawl and SEOnaut. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Crawls locally, calculates a quality score and tells you what to fix first; almost suspiciously on brief.
licenseMIT
runson your machine
installDownload a prebuilt desktop or CLI binary for Windows, macOS or Linux
enginesOptional OpenAI, Anthropic, Gemini, vLLM, Ollama, LM Studio or any OpenAI-compatible endpoint
dataRuns locally and writes project results plus HTML, JSON or text reports and exports to the user's disk
the catch vs SitebulbIts fix-first scoring is useful, but its prioritization and guided evidence are less polished than Sitebulb's.
setupNone for ordinary crawling; JavaScript rendering needs Chrome or Chromium, or the one-time headless-shell download
facts verified 2026-08-11
Unlimited crawls and a browser dashboard with audits; prioritization is plainer, but the evidence is there.
licenseMIT
runsyour server
installDocker Compose, or a Python environment plus Playwright
dataSettings live in browser localStorage; each browser session has isolated crawl data that expires after one hour unless exported as CSV, JSON or XML
the catch vs SitebulbIt has no durable project history and presents much plainer prioritization and evidence than Sitebulb.
setupDocker or Python plus Playwright is required, and local mode has no authentication unless the operator adds it
facts verified 2026-08-11
Stores audits and sorts issues by severity; not as pretty as Sitebulb, equally capable of ruining your afternoon.
licenseMIT
runsyour server
installDocker Compose with MySQL 8.4, then expose the web UI behind HTTPS
dataSites, crawl results and audit history live in the self-hosted MySQL database
the catch vs SitebulbIt produces a simpler severity list without Sitebulb's rich visual hints, explanations and guided investigation.
setupDocker, MySQL and a reverse proxy are required; its default exposed port is plain HTTP
facts verified 2026-08-11
A desktop crawler with 200 checks, issue evidence and project comparisons; the hint engine is younger, not imaginary.
licenseMIT
runson your machine
installWindows installer or portable build, macOS DMG, or Linux AppImage, deb or rpm
enginesOptional OpenAI, Anthropic and local Ollama; optional GSC, GA4, PageSpeed, Ahrefs, Moz, Semrush, Majestic and MCP connections
dataLocal SQLite WAL project files (.seoproject), optionally AES-256-GCM encrypted; exports include Excel, CSV, JSON, XML, HTML, sitemaps, Google Sheets and BigQuery
the catch vs SitebulbIts hint engine and visual prioritization are younger and less proven than Sitebulb's mature audit guidance.
setupThe prebuilt apps install normally, but the macOS build may require bypassing Gatekeeper for an unsigned application

RustySEOLooks like the obvious new answer; v0.3.9 and its own buggy warning say not for readers yet.
how to choose a Sitebulb alternative
Easiest to get running
SiteOne Crawler — a one-click install, no server to maintain.
Most proven
Plausible, with 23,000 GitHub stars — the largest community of the 8, which usually means more answers when something breaks.
Runs on your own machine, no server
SiteOne Crawler — nothing to host, your data stays on your disk.
Needs real ops to self-host
Mautic is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Sitebulb
- rule depth, visualization, reporting, JavaScript crawling, and agency workflow
- massive hosted crawl capacity
- proprietary scoring
- continuous monitoring
- agency reporting and support
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Sitebulb
People still pay for Sitebulb because a crawler is buildable; professionals pay for years of edge-case handling and reports they can trust with clients. The recurring cost buys robots handling, rendering, canonicalization, deduplication, crawl traps, rule maintenance, scheduling, storage, and false positives, not just the visible interface. If none of that applies to you, any pick above saves $216 a year.
