About this appAI proposal
Snagbook is a test and bug log for developers who already script their checks and use an AI assistant. A small local runner executes your test scripts on your own machine or CI. The app collects the results, groups failures and keeps a history of every bug.
You bring your own AI key, so the AI cost is what you already pay, with no AI markup. The AI reads failing runs, suggests a cause and drafts a fix prompt you can paste into your coding tool. Your scripts stay plain files you control.
It is for solo developers and small teams who find hosted AI testing agents slow and costly, and who would rather keep their own scripts than hand them to a cloud service.

- Why this name
- A snag is a small break found while working; a book is where you keep the list. Two plain words, easy to say and spell.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Local runner
Run tests on your laptop or CI. Nothing waits in a shared cloud queue, and only the results you choose are sent to the app.

Bring your own AI key
Use the AI account you already have for failure analysis. No bundled AI fee, and you can switch providers.
No member yet
Plain script support
Keep your own test scripts and mobile or web flows. Snagbook wraps them and records results; it does not replace them.
No member yet
Failure grouping
Failures with the same cause merge into one bug, so a broken login does not become forty alerts.

PricingAI proposal
Momentic's pricing page (verified) lists one paid plan at $125 a month, plus a free plan. These tiers undercut it and are a starting point to test; the material gives no other competitor prices.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Each bug and run has a shareable link and a status badge for a README or pull request. Teammates, contractors and reviewers open it to see the failing step and the fix prompt.
- Do they become customers?
- Viewers are developers, so some may sign up, but a link opened once is not a customer. Test whether badge and link viewers install the runner and reach a first recorded run.
- First customers
- Solo developers and teams of 2 to 5 shipping a mobile app, who already write test scripts and use an AI assistant, and pay for a hosted testing tool or avoid one on cost.
- Where to reach them
- Hacker News and developer forums: Share the open-source runner and a write-up of local versus cloud test speed in threads where cost and slowness are discussed.
- Open-source repositories: Offer the README badge and a pull request check to maintainers of mobile app projects with test scripts.
- Indie developer communities: Offer free setup help to a few makers in return for feedback and a case study.
- First milestone
- Ten teams record weekly runs for a month, and five of them pay for Solo or Team.
Why people already pay for this

- Public claimDevelopers prefer general AI tools combined with custom scripts over dedicated cloud testing services

RisksAI inference
- CommercialDevelopers who already combine an AI tool with their own scripts may see no need to pay for a log on top. Demand for a paid layer is unproven; the evidence is public comments only.
- TechnicalSupporting many test frameworks and mobile or web flows through one runner is a large surface. The first version must pick one or two formats and do them well.
- AICause suggestions may be wrong. Wrong guesses erode trust, so show confidence and the raw log next to every suggestion.
- DataLogs and screenshots can contain secrets or customer data. Runner-side redaction is needed before upload.
- PlatformA PWA cannot run tests itself; it depends on the runner being installed, which adds setup friction at first use.
