PreflightSEO exists because 30-80% traffic drops after site launches are preventable, but only if you know what to check.
Since 2018, I've been working in development agencies focused on websites and e-commerce. As a project manager for most of my roles, I was responsible for working with development teams and delivering the final product to customers.
We always had new projects being built, usually for people launching a new version of their website or migrating to a new platform. When marketing or SEO agencies weren't involved, the SEO verification task fell to me.
This usually became my responsibility because it isn't necessarily a developer's task. It resulted in me:
While some of this can be integrated with Screaming Frog, it is still a manual, labor-intensive hassle.
I recently built a new version of my personal blog. It generates actual traffic and runs Google AdSense, so it brings in revenue. During that process, I realized this could be done better, which is why I built PreflightSEO. I wanted the peace of mind of having an automated list I could rerun to ensure everything worked during my own migration.
Beyond using it for my own blog, I'm now using it for client projects at the agency where I work. This is the real reason I built the tool. All the potential SEO failures (missing redirects, forgotten noindex tags, broken canonicals) are things I've seen go wrong firsthand, and I've validated these issues through discussions with others on Reddit as well.

Make every site migration SEO-safe by default.
We're not trying to be an all-in-one SEO platform. We're not building rank trackers, keyword tools, or backlink analyzers. PreflightSEO does one thing: catch SEO regressions before a migration goes live. That's it.
Not a site auditor with a migration feature bolted on
Built by a developer, for developers and agencies
Clear pricing, no enterprise sales calls, no hidden limits
We do one thing well: migration comparison. We're not chasing every SEO feature under the sun.
Built by a developer who faced these problems. The UX is designed for people who ship sites.
No hidden fees. No "contact sales for enterprise." You see the price, you pay the price.
Real feedback from real users shapes the roadmap. We listen to Reddit threads, support emails, and user interviews.
"We're not building an all-in-one SEO platform. We're building the best migration checker on the planet."
