How Tech Stack Detector detects Replit
Replit is matched from these signals during a single, ordinary page request. Each one contributes to the confidence score shown on a scan.
- PlatformPublished on a Replit deployment subdomain (replit.app)
- TemplatePlaceholder page description written by Replit Agent
- TemplateReplit development banner script from the Replit app template
- Template"Made with Replit" badge script
Platform evidence comes from Replit's own hosting or runtime and gives a Confirmed result. Template evidence is left in the code Replit generates and gives a Strong evidence result, because an owner can edit it out. Replit also runs hand-written projects, so a match confirms the platform, not that AI wrote the code. See how accurate the AI builder check is

Frequently asked questions
What is Replit?
Replit is an AI app builder: Cloud development platform whose Replit Agent builds, runs and hosts apps from prompts. Tech Stack Detector identifies Replit on any website by analysing the hostname that serves the site, the HTML source and script URLs. Its official website is https://replit.com.
How can I tell if a website uses Replit?
Enter any URL into Tech Stack Detector and it reports whether Replit is present, with a confidence score and the exact evidence it matched. Detection is based on the hostname that serves the site, the HTML source and script URLs. No login or crawling of the site is required.
Can a website hide that it was built with Replit?
Only partly. Badges and default tags can be removed, but the fingerprints that come from Replit's own hosting cannot be removed while the website stays on Replit. After the code is exported and hosted elsewhere, only the tags left in the generated source remain, and an owner can delete those too. In that case Tech Stack Detector reports no evidence instead of guessing.
What are some alternatives to Replit?
Other AI Builder technologies Tech Stack Detector detects include Lovable, Base44, Emergent, Bolt.new, v0 and Manus. You can compare any of them side by side with Replit.
