Kits: from download to running in your stack
- 01Pick the kit and the licence
Solo covers one developer, Team covers your whole team, Agency covers unlimited client projects. Same source in all three.
- 02Download the source
Instant, after checkout. Hand-written TypeScript with its tests, migrations, adapters, a working example and real docs.
- 03Drop it into your stack
Cloudflare Workers-first where it applies, with a generic Node adapter. It runs on your keys and your infrastructure — nothing phones home.
- 04Keep it current
Twelve months of updates come with every kit, including the maintained tables the code depends on.
One licence ladder, every kit
A kit is licensed to the people who build with it, not to the site it ends up in. Ship what you make on top and keep whatever you charge for it. Each kit prices its own rungs — the range below is what the 7 kits on the shelf actually charge, and every kit's page states its licence in its own words.
Solo $59 – $399
One developer, on their own projects.
Team $119 – $899
One team — internal work and client work alike.
Agency $299 – $1,900
Unlimited client projects.
Building on one?
See the kits Every kit states its own limits.
Each kit's page carries the count of tests green at packaging, and a plain answer to "what does it deliberately not do" — the SQL dialect it ships, the feature it leaves to you, the rows it flags rather than guesses. Read that section before you buy, not after.
Questions
How is a kit different from a template?
A template is a finished website you edit and publish. A kit is production source code you build on — the ledger, the gateway, the harness, the pipeline — meant to be read, extended and shipped inside your own product. Templates are licensed per site; kits are licensed per developer, team or agency.
Can I ship it in a product I sell?
Yes. Solo covers one developer's own projects, Team covers a team's internal and client products, Agency covers unlimited client projects. You keep whatever you charge for what you build on top.
Is the code actually tested?
Every kit ships with its own automated suite and the count is on its page — run on a clean-room install at packaging, not on our laptops. Each kit's page also states plainly what it deliberately does NOT do, so you find the limits before you buy rather than after.
Do I need your infrastructure or an account with you?
No. Kits run on your keys, your accounts and your hosting. There is no service to sign up for, no runtime dependency on us, and nothing calls home.
