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.
@bensenescu The GSC loop is the part I'd stress-test. When we wired an agent to the Search Console API, the last 2-3 days of rows were still settling, so anything published Friday read as flat until Monday and the agent kept trying to "fix" work that was actually fine. We ended up throwing away the trailing 72 hours before letting it draw any conclusion. Does yours hold that window back, or does it read the freshest rows it can get?
The SEO tool market has needed price pressure for years. Incumbent pricing assumes an agency budget, and I run SEO for a niche B2B product paying for data I mostly do not use. I saw the sourcing question below already, so mine is about the long tail: niche B2B keywords (healthcare software in my case) often show zero or missing volume even in the big tools. How does OpenSEO handle those low-volume terms, does it estimate, show zero, or mark them as no-data? For niche products the long tail is the entire game, so that answer matters more to me than head-term accuracy. Congrats on the launch, the open source route is the right wedge here.
I've been on the content side for a while — writing-focused, not SEO-first — and the pricing of every serious SEO tool has always assumed you're an agency running five client accounts. You just need to know which topic gaps actually exist before you spend three weeks writing something nobody will find.
The open-source angle here matters more than the price tag, though. Most content people I know aren't going to self-host anything, but knowing the data layer is DataForSEO and auditable changes how much you trust the keyword numbers. Black-box confidence scores are the part that always made me discount the recommendations anyway.
Congrats on shipping this — curious how the content-brief workflow compares to using the backlink data directly for topic research rather than competitive analysis.

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

@demet46p6 What writing apps do you use right now? What do you like about them?
