AI App Builders

Prompt-to-app platforms that generate and host full applications. The tools most vibe-coded apps ship from, and where most of the security findings in our scan pipeline come from.

Base44

not yet scanned

All-in-one no-code AI builder (acquired by Wix) that generates apps with built-in database, auth, and hosting, so there is no separate backend to configure. That integration cuts out common wiring mistakes but concentrates trust in the platform's own access controls, which security researchers have probed publicly.

Best for
Non-coders who want database and auth handled inside one platform
Full listing and scan status

Bolt.new

not yet scanned

StackBlitz's in-browser AI builder that scaffolds and runs full-stack JavaScript apps entirely in the browser, then deploys them. Fast iteration loop; the generated projects commonly pair with Supabase or Firebase, so database rules and key handling are the main things to check before launch.

Best for
Rapid prototyping of JavaScript and TypeScript web apps
Full listing and scan status

Create

not yet scanned

Text-to-app builder for sites, apps, and internal tools with integrations for auth, payments, and AI features. Sits in the same prompt-to-product lane as Lovable and Bolt, with generated projects that ship quickly and deserve the same pre-launch checks on data access and secrets.

Best for
Marketing sites and lightweight products with built-in integrations
Full listing and scan status

Databutton

not yet scanned

AI developer that plans, builds, and deploys full-stack apps with a Python FastAPI backend and React front end. The explicit backend is a real difference from browser-only builders: server code exists, so API auth and input validation are the checks that matter most.

Best for
Data-heavy apps and founders who want a real Python backend
Full listing and scan status

Lovable

not yet scanned

Prompt-to-app builder that generates full-stack web apps, typically on a React front end with Supabase for database and auth. One of the most popular routes from idea to shipped app, which also makes Lovable-built apps the most common subject of public security incidents involving exposed Supabase tables and keys.

Best for
Non-technical founders shipping a SaaS MVP fast
Full listing and scan status

Replit

not yet scanned

Cloud IDE with Replit Agent, which builds and deploys full apps from a prompt onto Replit's own hosting and database. The platform manages secrets and deployment for you; the security questions that matter are about the apps the agent generates, not the platform itself.

Best for
Going from prompt to hosted app in one place, including the database
Full listing and scan status

v0 by Vercel

not yet scanned

Vercel's generative UI and app builder. Strongest at producing React and Next.js interfaces with shadcn/ui, increasingly capable of full apps deployed straight to Vercel. Output quality is high on the front end; server-side auth and data access still depend on what you wire it to.

Best for
React and Next.js interfaces and Vercel-native apps
Full listing and scan status

AI Code Assistants

AI-first editors and coding agents. They write the code but you own the deploy, so security posture depends heavily on the stack you pair them with.

Claude Code

not yet scanned

Anthropic's terminal-based coding agent that plans and executes multi-file changes, runs tests, and manages git from the command line. Used heavily for agentic builds and refactors; as with all assistants, the shipped app's security depends on the stack and the review discipline around the agent.

Best for
Agentic, test-driven development from the terminal
Full listing and scan status

Cursor

not yet scanned

AI-first code editor built on VS Code, with agentic multi-file editing across essentially any stack. Cursor writes code in your own repo and you own the deployment, so the security posture of a Cursor-built app is set by your stack choices, not by the editor.

Best for
Developers and technical founders who want AI speed inside a real editor
Full listing and scan status

GitHub Copilot

not yet scanned

GitHub's AI pair programmer, now with agent mode and workspace-wide edits inside VS Code and JetBrains IDEs. The most widely deployed code assistant; studies of AI-generated code quality, including insecure suggestion rates, most often use Copilot output as the baseline.

Best for
Teams already living in GitHub and mainstream IDEs
Full listing and scan status

Windsurf

not yet scanned

Agentic AI editor (formerly Codeium) whose Cascade agent handles multi-step, multi-file coding tasks with deep codebase awareness. Like Cursor, it operates on your own project and infrastructure, so pre-launch security checks belong to the app, not the tool.

Best for
Agentic coding workflows on existing codebases
Full listing and scan status

Backend and Auth

The databases and auth layers vibe-coded apps sit on. Misconfigured row-level security and exposed keys in these services account for a large share of real-world incidents.

Clerk

not yet scanned

Drop-in authentication and user management for React and Next.js, with prebuilt components for sign-in, sessions, and organizations. Popular in AI-generated codebases because it removes the hand-rolled auth that scanners most often flag as broken.

Best for
Next.js apps that want production auth without building it
Full listing and scan status

Firebase

not yet scanned

Google's app platform with Firestore, Realtime Database, auth, and hosting. A long-standing target of misconfiguration research: security rules left in test mode expose entire databases, the same failure class Supabase RLS misconfiguration produces in newer stacks.

Best for
Mobile-first and Google-ecosystem apps
Full listing and scan status

Neon

not yet scanned

Serverless Postgres with branching and scale-to-zero, increasingly the default database on Vercel and inside AI builder stacks. Plain Postgres semantics mean no client-exposed API by default, which removes one failure mode Supabase-style stacks have to configure away.

Best for
Serverless Postgres for Vercel and Next.js apps
Full listing and scan status

Supabase

not yet scanned

Open-source Postgres backend with auth, storage, and auto-generated APIs. The default database behind Lovable and much of the vibe-coding ecosystem. Its row-level security model is powerful but off by default on new tables, which is the single most common root cause behind publicly readable data in shipped vibe-coded apps.

Best for
Postgres-backed apps that need auth and instant APIs
Full listing and scan status

Security Scanners

Tools that check a vibe-coded app for exposed databases, leaked secrets, and missing auth before and after launch.

Aikido Security

not yet scanned

Developer-focused security platform combining code scanning, dependency checks, secrets detection, and cloud posture in one tool. Broader and more enterprise-shaped than vibe-app scanners; relevant when a vibe-coded MVP grows into a product with a real team.

Best for
Teams graduating from MVP checks to continuous appsec
Full listing and scan status

Passive, read-only security scan for vibe-coded apps: exposed database tables, leaked API keys and secrets in served bundles, missing auth on endpoints, and launch-readiness basics. The scan engine behind this directory's grading data and methodology.

Best for
Founders who want a pre-launch check with a human review behind it

VibeAppScanner

not yet scanned

Security scanner aimed at vibe-coded apps, with a large library of per-tool security guides, risk pages, and fix instructions across Lovable, Bolt, v0, Supabase, and others. Listed here on the merits; it competes with this directory's own scanner.

Best for
Self-serve scanning with extensive written guides per tool
Full listing and scan status

VibeEval

not yet scanned

Scanner and safety-rating site for AI app builders, including a free Supabase RLS checker and per-tool safety pages. Publishes its own scanned-apps count. Listed here on the merits; it competes with this directory's own scanner.

Best for
Quick RLS checks and per-builder safety summaries

Deploy and Hosting

Where the generated apps actually run. Hosting choice shapes what an attacker can reach: environment variables, source maps, server functions.

Netlify

not yet scanned

Web platform for static and serverless-backed sites with functions, forms, and edge handlers. A frequent deploy target for Bolt and other builder output; the same environment-variable and function-auth checks apply as on any serverless host.

Best for
Static-first sites with serverless functions
Full listing and scan status

Railway

not yet scanned

Infrastructure platform that deploys full services and databases from a repo with minimal configuration. Popular for vibe-coded apps that outgrow browser hosting and need a real server process plus a managed Postgres in one place.

Best for
Full-stack apps that need long-running servers and databases
Full listing and scan status

Vercel

not yet scanned

The default deploy target for Next.js and v0 output, with preview deploys, edge functions, and managed environment variables. Common vibe-code pitfalls on Vercel are client-exposed environment variables with the NEXT_PUBLIC prefix and shipped source maps.

Best for
Next.js and frontend-first apps
