SEO and marketing
Ahrefs alternatives
1 open-source project that already does this job. Free to use - not free to run, which is what the numbers on the right are for.
The projects
What you give up either way
- Ahrefs’ proprietary web index and its coverage/freshness
- Large-scale crawling infrastructure and data volume (hundreds of billions of pages)
- Built-in enterprise features such as uncapped API access, SSO, ISO27001 controls
- Pretrained/custom LLMs and any proprietary models or derived datasets
- Advanced integrations and premium reporting/automation add-ons
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Ahrefs, and it does not prove anyone has run it for a month. How we decide.
