What is Base44?
Base44 is an AI-first app-building platform. Describe an app in natural language and Base44 generates a full-stack web app you can iterate on and deploy from the same builder.

Short guides
Base44 vs Lovable vs Bolt
Three AI app builders with different bets on runtime and backend. Base44 and Lovable run generation server-side and ship managed hosting; Bolt runs entirely in a browser WebContainer.
How AI generation actually fails
Most 'stuck build' incidents are upstream LLM outages — Anthropic or OpenAI — not the builder itself. Always cross-check the LLM provider's status page before assuming the platform is down.
Reading a status page
A green dot on this site means an endpoint's DNS/TCP/TLS is reachable. It does not guarantee generation, deploys or the internal builder are healthy — those run on systems we can't probe from a browser.
Why CORS limits browser checks
AI app-builder platforms don't return permissive CORS headers, so browser checks confirm the network handshake — not a full JSON response. That's why we report reachability, not full health.

Communities
Glossary
- Vibe coding
- Building software primarily by prompting an LLM instead of writing code by hand.
- AI app builder
- A platform that turns a natural-language prompt into a working full-stack app — Base44, Lovable, Bolt, Replit Agent.
- Generation
- A single prompt-driven code change. Usually rate-limited per plan.
- WebContainer
- StackBlitz's in-browser Node.js runtime — how Bolt runs code without a server-side sandbox.
- Managed hosting
- Hosting run by the platform itself (Base44, Lovable), as opposed to hosting on a third-party like Netlify or Vercel.
- Custom domain
- A domain you own pointed at a platform's hosting via DNS records.
- LLM provider
- The frontier-model API powering generation — Anthropic (Claude), OpenAI (GPT). Their outages break generation.
- Deploy artifact
- The compiled, built version of your app that hosting actually serves.
- Reachability check
- A browser-side DNS/TCP/TLS check that a URL is responding — the only kind of check possible without CORS access.
- Cold start
- The extra latency when a serverless deployment boots after being idle.
- Nix
- The declarative package manager Replit uses to define container dependencies.
- Supabase / Lovable Cloud
- The managed Postgres + auth backend that Lovable ships by default.
FAQ
Is Base44 down right now?
Check the dashboard on the Base44 status page and cross-reference status.base44.com. If both are green and generation still fails, it's usually an LLM-provider outage.
What's the difference between Base44 and Lovable?
Both are AI-first app builders shipping to managed hosting. Lovable is Supabase-centric (branded as Lovable Cloud); Base44 ships its own backend primitives and hosting stack.
Why does this site show reachable but I can't build?
Browser checks only see public front-ends. Generation runs on LLMs upstream — the builder's own front-end can be green while the LLM API is degraded.
Do you build apps or hold code?
No. base44.health is read-only — we run public reachability checks and link out to each platform.
