Paid Node source kits
Skip the billing and license plumbing that slows SaaS launches down.

Live Gumroad Listings
MRR analytics, invoice tax metadata, cancel-save flows, usage alerts, and team seats are separate kits so you only buy the missing workflow.
Each live kit links to its Gumroad checkout from the buyer guide, product feed, and LLM-readable summary.
Packages include source, README, manifest hashes, buyer smoke tests, and delivery notes instead of a hosted black box.
Sample Direction
Product launch
A focused first screen, clear offer, and buyer-ready call to action.
Designed for founders, freelancers, service firms, and small tools that need a credible page before a launch or ad test.
Stripe card, Base USDC, Calendly, waitlist, or contact form placement.
Example First Draft
Local service page
Book reliable exterior cleaning before the next busy weekend.
A first draft like this can turn a rough service note into a clear page with the area served, the jobs handled, a simple booking CTA, and proof blocks a buyer can scan in seconds.
Audit Sample
Replace vague launch copy with the buyer, outcome, timeframe, and first action in the first screen.
Move the primary CTA above the fold and repeat it after proof, pricing, and the FAQ instead of hiding it in the nav.
Add one compact proof block: who it is for, what is included, and what happens immediately after payment or signup.
Why Paid
You get the three highest-leverage fixes for the page you submit, not a long automated checklist.
Each audit points to the exact section to change and includes clearer wording or placement direction.
If the page needs more than fixes, the $25 sprint turns the audit into a usable one-page build.
Scope
- Best for one-page launches, portfolios, local services, tiny SaaS/tools, and proof-of-concept offers.
- Buyer provides product details, logo if any, preferred links, and any required images through checkout or the revision pass.
- No fake claims, scraping, account creation, password handling, regulated advice, or spam tooling.
Delivery Flow
Checkout collects the URL or project brief, main goal, and primary CTA.
The first audit or page version is prepared within 24 hours after payment and usable scope are received.
For the $25 sprint, one focused revision pass is included for copy, layout, or CTA adjustments.
Payment
$5 audits and $25 page sprints are available by Stripe card. The checkout collects the brief needed to begin. Base USDC is preferred for direct fixed-scope work.
