Every check runs live against real servers: DNS lookup, SSL/TLS and security headers, website analyzer with PDF reports, SEO and Core Web Vitals, TTFB, CDN and compression tests, IP geolocation, WHOIS, ASN and blacklist checks. Developer utilities include a JSON formatter and validator, regex tester, Base64, UUID, SQL/HTML/CSS/JS formatters and minifiers. Results come as clear reports with scores and ready-to-paste fixes for Apache, nginx and Cloudflare. No sign-up, no limits, fully in English and Turkish, and works on mobile.

Supabase is an open-source backend platform built on PostgreSQL, founded in 2020 by Paul Copplestone and Ant Wilson. It started as an open-source alternative to Firebase and has become one of the most popular backends for web, mobile and AI applications, especially among TypeScript, Next.js and Flutter developers.

Every project is a full Postgres database with extensions such as pgvector, plus auto-generated REST and GraphQL APIs, so the frontend can query data directly while row-level security policies protect it. Authentication supports email, magic links, OAuth providers, phone and multi-factor login. Storage serves files through a CDN with image transformations, Edge Functions run server-side TypeScript on Deno, and Realtime pushes database changes and broadcast messages to clients. Branching creates isolated databases for previews. A free plan covers two projects with limits and pauses inactive projects, Pro costs a fixed monthly fee with usage-based extras for compute and bandwidth, and Team and Enterprise add compliance, SSO and support.

Supabase suits startups, indie developers and product teams that want a managed backend without giving up SQL or the option to self-host. Costs rise with compute add-ons and egress at scale, and complex multi-region write needs are outside its sweet spot. Firebase remains strong for real-time mobile apps on Google Cloud, Neon focuses on serverless Postgres alone, and Appwrite and PocketBase are other open-source backends. AI app builders such as Lovable and Bolt use Supabase as their default backend.
