Now in private beta

Ship working software,
not beautiful guesses.

Every AI builder generates code. Kortex verifies it compiles, repairs its own errors, and boots a live preview before handing anything back. No more "looks good in the demo, falls over in production."

Your turn
Build me a habit tracker with streaks, reminders, and a leaderboard
kortex — synthesis
// planner.ts — creating task graph
const tasks = ["habit-tracker-db", "streak-logic", "reminder-cron", "leaderboard-agg"];
4 tasks planned, dependencies resolved
// synthesis — generating src/pages/index.tsx
src/lib/streaks.ts:14 — TS2345: Argument of type 'Date' is not assignable to parameter of type 'number'
Repairing... streakLogic(lastActive).getTime()
TypeScript: 0 errors, 0 warnings
Sandbox: kortex.run/habit-tracker-4f2a
GitHub: PR #12 opened
Deployed and verified. 15 seconds.

Five steps. One working app.

Other tools generate and hope. Kortex generates and verifies — in a loop, until it actually works.

01

Plan

Break your idea into a task graph with clear dependencies. No hallucinated features.

02

Synthesize

Generate full-stack Next.js with tRPC, Prisma, and Tailwind. Provider-neutral AI pipeline.

03

Typecheck

Run the TypeScript compiler as a first-class citizen. Catch errors before the agent moves on.

04

Repair

Self-repair loop: run diagnostics, feed errors back to the agent, re-verify until clean.

05

Ship

Sync to GitHub, deploy to Vercel, share a live preview link. All from the same chat.

// Compiler-in-the-loop verification
run_typecheck(files) → {"errors": [], "warnings": []}
// Agent must call this before finish

Everything you need to go from idea to production.

Docker
E2B Cloud
SandboxDriver interface — swap implementations without changing the pipeline

Isolated sandboxes, every time

LocalPreview for instant mock demos. Docker for hardened ephemeral environments. E2B for cloud microVMs. Each sandbox boots Next.js, runs Prisma migrations, and returns a live URL — before Kortex marks the task done.

Demo mode with zero config

Every competitor requires API keys before anything works. Kortex's mock mode uses deterministic templates so you can see a real working app in under 60 seconds — no Anthropic key, no OpenAI account, nothing.

Next.js 14 App Router + React 18
tRPC + Prisma (Neon / Supabase / pglite)
Tailwind CSS
BullMQ worker (Redis fallback)
Custom auth — scrypt + Google OAuth + signed cookies

Full-stack, production-grade stack

Not a toy template. Real tRPC, real Prisma migrations, real auth with RBAC and per-plan daily quotas. Monorepo with pnpm + Turborepo. Everything wired up, nothing mocked.

GitHub and Vercel as first-class citizens

Other tools lock you into their hosting. Kortex syncs to your GitHub repo and deploys to Vercel — you own the code and the infrastructure. Incremental commits, real branches.

Every AI builder has the same flaw.

Built for founders who can't afford to guess wrong.

Indie founder beachhead

Lovable targets agencies. Replit targets education. Bolt targets senior devs. Solo founders building solo SaaS are the most underserved segment — most pain, most loyalty, most need for something that actually works.

Verification is the moat

No competitor puts compiler-in-the-loop at the core. They generate and ship, hoping it works. Kortex's self-repair agent using real tsc diagnostics is a fundamentally different architecture — and it's what makes "always demoable" possible.

Own your code

Lovable and Bolt have their own hosting. Kortex syncs to your GitHub and deploys to Vercel. You leave with a real repo, real infrastructure, real ownership — not a walled garden.

Demo in 60 seconds, zero config

Mock mode with deterministic templates means anyone can see a working app without connecting a single API key. That's a dramatically different onboarding experience than "sign up, configure, wait, maybe it works."

The vision

Every idea deserves a working prototype.

Not a mockup. Not a guess. A verified, running, deployable app — generated from plain English, shipped to your GitHub, live in under two minutes. No engineers required. No "try again in production."
