Tabkeel

Tabkeel is a website auditing tool built for SaaS shipped with AI (Lovable, v0, Bolt, Cursor). Paste a URL and it crawls the site to find what is broken or contradictory: dead links, blank 404s, prices on the pricing page that do not match the terms, and pages that AI assistants cannot read. Every finding comes with clickable proof and a paste-ready fix you can drop into a code agent. The exam is free and runs without signup; paid plans keep watching the site and its AI visibility and alert you when something breaks.

upsonar.io

Most uptime monitors only check if your server responds. upsonar goes further — it loads your page and discovers every external dependency: CDN-hosted files, third-party scripts, web fonts, and API endpoints. If any of them fail, you get alerted before your users notice. Availability checks run from multiple global regions simultaneously, so regional CDN failures and localized outages don't go undetected. Beyond uptime, upsonar monitors SSL certificates approaching expiration, tracks domain expiry dates to prevent renewal failures, and detects DNS record changes that could indicate unauthorized modifications. All five monitoring types work together in one dashboard. Notifications reach you through email, Telegram, or webhooks compatible with Slack, Discord, and PagerDuty. Get started free with 3 websites — all features included, no credit card needed.
