About
Spec Coding is a practical resource hub for spec-first software development. It helps developers, founders, product teams, and QA reviewers write a small spec.md before implementation starts, so scope, non-goals, acceptance criteria, API contracts, rollout notes, and test evidence are clear before code review. The site includes free Markdown templates, browser-based spec generators, complete SDD change packets, acceptance criteria examples, and AI coding review workflows. It is useful for teams using AI coding tools, solo builders who want less rework, and engineering groups that need requirements to become reviewable artifacts instead of vague tickets. Spec Coding stands out by keeping the workflow simple: structure first, implementation second, and testable acceptance criteria before code.

When we launched Fitness AI we hard-paywalled everything. The people who paid were telling us: this is real, this is a problem worth solving, and we're willing to put money down. That validated the product far faster than free users ever could.
Paywalling everything at launch filters for users whose problem you actually solve
Moore argues that free tiers at launch add noise: free users are exploring, not confirming product-market fit. Paying users from day one constitute a cleaner signal — if strangers pay without persuasion, the problem and solution are real. The additional benefit is financial: early revenue funds iteration without fundraising urgency. The trade-off is slower install growth, which Moore accepted as a fair price for signal quality.
I currently sell the paid version at $99 a year or $159 for 2 years both are non-recurring subscriptions that users have full control over and can choose to renew at the end of their term.
Sell Non-Recurring Annual Plans At $99 Or $159 To Build Trust Without Crushing Revenue
Lewis prices Audio Pen at $99/year or $159 for 2 years, both as non-recurring subscriptions. Users opt back in at renewal rather than getting auto-charged — a trust signal that costs some auto-renewal revenue but earns goodwill, lower refund rates, and word-of-mouth from a niche audience that values control.
There's a play for whatever you're stuck on.

1I built Spec Coding to make AI-assisted development less vague. The main idea is simple: write a small, reviewable spec before coding so scope, acceptance criteria, and test evidence are clear from th
