Without good data, your agent gives generic advice. Keyword research, competitor research, backlinks and site audits, starting at $10/month instead of a $100-plus monthly subscription. Connect with MCP so that you can work with your agent to build an SEO strategy and write content tailored to your company.

finally, an open-source alternative to @Ahrefs and @SEMrush. it's about time.
S/O to @bensenescu, keep up the great work. oss ftw!
@bensenescu
Glad someone finally built this. A lot of small teams give up on SEO before they start, because the tools cost $100/mo before you've written a single post.
So the pricing is what caught my eye. Backlink and keyword data is usually the expensive part — how are you sourcing it? Own crawler, or licensing an index?
The MCP angle is interesting too. We work on the content planning side, and what we keep seeing is that agents will build a whole strategy on bad keyword data and sound completely confident about it. Do people trust the output more when the numbers are real, or does it just move the guessing one step later?
Starred the repo. Hope this one does well.

@saied_alimoradi We use DataForSEO which is the gold standard for backlinks + keyword data outside of Ahrefs and Semrush. It definitely makes a huge difference compared to just asking Claude "what should I do?" without data to back it up.
Hope that helps! let me know if you have other questions
@bensenescu That matches what we see. The confidence is the dangerous part — an agent with no data still sounds just as certain, so nobody can tell the difference until much later.
Thanks for the straight answer on the data side.
@saied_alimoradi @bensenescu Awesome, started using this last week and a friend was asking wherw the Data was sourced. Good to knkw

Hello 👋
This February, I was building other open source projects and wanted to do SEO.
I was floored by how expensive and bloated the tools were. There weren't any modern open source solutions, so I figured I should just build that.
Since then, it's been really cool seeing founders and agencies enjoy the product and even building their own custom features.
Hope you give it a try: openseo.so. There are some trial credits to test it out, then it starts at $10/month.
You can also self host on Cloudflare or with Docker.
Give us a star on github or you can join the discord to get SEO advice, contribute, or just hang out.
SEO has increasingly become an expensive play. You have found the right gap@bensenescu. I will give a try.
@bensenescu Curious how the MCP layer handles batch queries. If an agent fires off twenty keyword lookups back to back, is that twenty separate API calls on your end, or do you batch or cache anything in between?
Love the pricing and the MCP angle is really smart. One thing that would help me as a user is a built-in content brief generator that pulls the keyword, competitor, and backlink data together into a single outline my agent can act on. Right now I still end up stitching the pieces together myself in a doc.

@resulolys Thanks! Yes, I like that content brief idea. It's been on the todo list for a while. The tough part is getting it to work for all different kinds of users. I've been thinking of building something like Hermes for self updating skills. Would you just want blogs or lots of different kinds of content?
One thing that would make this way more useful for me is letting the MCP agent pull historical ranking data so I can see if keyword positions are actually moving over time, not just a snapshot of what the competitor looks like today.

@ecilkaya58405 Thanks for this feedback! Definitely something we can add, I'll open a github issue today. What kind of SEO work do you do typically?
would be awesome if you could add a content brief generator that pulls keyword and competitor data straight from the dashboard into a doc template, basically saving the back and forth between the tool and writing apps
the self-host on Docker/Cloudflare option is what caught my eye - when you self-host, do you bring your own DataForSEO key and eat that cost directly, or is the metered usage still billed through your $10/month even for the self-hosted version?
