As answered by people managing OpenSEO and https://open-gpt.app/.
OpenSEO's answer
Choose OpenSEO if you are new to SEO or if you're fed up with your expensive and bloated tool.
OpenSEO's answer
I built OpenSEO because I wanted to start doing SEO for my startup and I was blown away by how expensive they had become. Even the entry level tools were littered with paywalls and upsells.
I made OpenSEO so that people can have a more pleasant experience while trying to improve their websites ranking.
OpenSEO's answer
OpenSEO is pay by usage. Rather than committing to $100+/month subscriptions, you pay only for what you use. The managed product starts at just $10/month.
