How it works

Three steps from repo to launch path.

Toolbound gives your coding agent the stack, context, and guardrails before it starts editing. That keeps beginners out of setup loops and keeps the commercial rails intact.

01step

Open the repo

Download Toolbound, push it to your own GitHub, and open it with Claude, Codex, Cursor, or Windsurf.

1. Download repo
2. Add your product idea
3. Open with your agent

02step

Choose how it sells

Pick paid beta, freemium, or lifetime deal before the agent starts changing pricing and onboarding.

✓ Paid beta
✓ Freemium upgrade
✓ Lifetime deal

03step

Verify before launch

Run the built-in checks so the agent does not quietly break payments, emails, setup, or the build.

> npm run verify
setup-check ok
tests ok
build ok

Agent guardrails

The value is the rails, not a list of ideas.

Toolbound helps a coding agent understand the repo before it edits. The buyer gets implementation scaffolds inside the download; the public site focuses on the system that keeps payments, email, auth, and setup intact.

See the agent handoff

rail

Repo memory

AGENTS.md, CLAUDE.md, architecture notes, and glossary files tell the agent how the product is meant to work.

rail

Safe edit zones

The handoff docs separate files an agent can customise from commercial rails it should preserve by default.

rail

Launch flow

Paid beta, freemium with upgrade, or lifetime deal decisions are made before the agent rewrites pricing.

rail

Verification checks

Setup checks, tests, linting, and build commands give the agent a concrete pass/fail loop before launch.

rail

Commercial rails

Stripe, Resend, Postgres, Clerk-ready auth, download delivery, and setup docs are already mapped together.

Buyer-only briefs

Workflow briefs are included inside the download as customisation scaffolds, not public business ideas.

A note on the example subscription plans

The Starter / Pro / Agency tiers you see inside the demo app are example pricing the generated SaaS uses for its own subscribers. They are wired through the code so you can edit them in one place when you launch your own product. The fee above is what you pay us for the repo.

Delivery

Self-serve checkout. No sales calls. No managed hosting.

Checkout

Stripe collects payment. Order written to Postgres on webhook.

Zip download

Hosted Toolbound Stack zip sent to the buyer email on the order.

Onboarding email

Setup steps, brief index, and links to AGENTS.md land in inbox one.

Setup docs

Self-serve guides walk through env, Stripe keys, and first deploy.

What support covers

Setup help via email for env, Stripe, and deploy questions
Repo-level bug fixes when something we ship is broken
Customisation briefs + agent docs kept up to date

What we do not do

Host or operate your product for you
Write your custom features or do bespoke implementation
Manage your customers, API keys, or compliance

Google Search Console connector spec

A documented path for connecting verified search data later.

The stack includes the connector brief and setup docs. The production OAuth/MCP server is not included yet, so buyers should treat this as an implementation spec for their agent, not a live managed integration.
