The coding agent that doesn't stop halfway.
Htvag Agent runs on your machine, edits your real codebase, executes your test suite, and keeps working until the thing you asked for actually works. No “next, you should”. No half-finished stubs.
No setup required · The agent runs locally — your source never touches our servers
› add stripe checkout to the pricing page and make sure it builds ✓ grep "pricing" page exists, no checkout yet ✓ read app/pricing/page.tsx plain pricing cards, no buy button ✓ read package.json stripe isn't installed ◷ plan 5 steps ✓ bash pnpm add stripe ✓ write app/api/checkout/route.ts new checkout session route ✓ edit app/pricing/page.tsx wire the buy button to it ✓ edit .env.example add STRIPE_SECRET_KEY ✗ bash pnpm build type error: priceId possibly undefined ✓ edit app/api/checkout/route.ts narrow the type, rebuild ✓ bash pnpm build passes Done. Checkout session is created server-side, price ids come from env, build passes. STRIPE_SECRET_KEY still needs a real value before deploy.
What makes it different
Most assistants generate code and hand it back. This one owns the outcome.
It finishes the task
A completion gate inspects every turn. Open todos, unverified edits, or a reply that defers work back to you all push the agent to keep going instead of stopping.
It verifies its own work
Changes get built, type-checked and tested before the agent claims success. Failures feed back into the loop as the next thing to fix.
Real tools, real repo
Read, glob, grep, precise string edits, and a persistent shell where cd and exports survive between commands — the same primitives a human engineer uses.
Built for web apps
Next.js, React, TypeScript, APIs, auth, databases. It knows server components from client ones, and where a secret must never end up.
Streams everything
Reasoning, tool calls, and diffs arrive live as the work happens. You watch it build the thing instead of waiting on a spinner.
Nothing to configure
Sign in and start working. No API keys to find or paste, no model to pick — a daily quota is included on every account. Your code never leaves your machine.
From download to shipping
Install the desktop app
Windows, macOS or Linux. One binary, no runtime to set up.
Sign in through the browser
The app opens this site, you approve, and you're signed in automatically — nothing to copy or paste.
Open a folder
Point it at a repo. It reads package.json, detects your stack, and learns your build commands.
Describe the outcome
Not the steps — the result. It plans, edits, runs, fixes and reports back.
Give it the outcome. Get the outcome.
Install the desktop app, open a repo, and describe what you want to exist.
