Free website checks, no API key: geo_audit scores AI search readiness (AI crawlers, sitemap, llms.txt, structured data) with copy-paste fixes, spof_scan finds single points of failure in a domain's DNS, email and hosting providers, and decode_error explains Bubble app error messages.
Scored across 3 tools
Each tool targets a completely different input and domain: a Bubble error message, a website's AI/SEO readiness, and a business's vendor dependency graph. There is no plausible way to confuse geo_audit with spof_scan or decode_error, since the descriptions clearly separate the resource being analyzed.
All three names use lowercase snake_case two-part compounds (verb_noun style: decode_error, geo_audit, spof_scan), which is predictable. The only minor wobble is the 'spof' acronym, which is less readable than the other two names but still follows the same pattern.
Three tools is on the lean side, but this is explicitly a free, no-key diagnostics toolkit, so a small focused set is appropriate. Each tool covers a distinct check and none feels redundant.
The domain is read-only auditing/diagnostics, and the surface covers three separate, self-contained checks, each returning actionable output (scores, pass/warn/fail, fixes). There is no lifecycle gap because no create/update/delete operations are implied; only minor depth gaps exist (e.g. audits read a limited set of files).
Explain an error message from an app built on Bubble: the likely cause, a link to the full fix and the fixed-price service that fixes it. Matches the text against the same list as the decoder page at redcenterstudio.com/decoder/. Free, no key.
Inputs: error (required).
Check how ready a public website is for AI assistants and search engines: AI crawler access in robots.txt, sitemap, llms.txt, structured data, titles and page basics. Returns a score out of 100, each check with pass, warn or fail, and copy-paste fixes. Reads the home page, robots.txt, sitemap.xml and llms.txt only. Free, no key. Rate limited per connection.
Inputs: url (required).
Find which companies a business depends on for email, sign-in, DNS, website hosting, outbound email and SaaS, using public DNS only, and what a single outage would stop. Returns the layers, the vendors, a risk score and recommendations. Free, no key. Rate limited per connection and to about 20 fresh scans an hour; repeat scans of the same domain within an hour come from cache.
Inputs: domain (required).
