Developer Tool Idea Scorer
Score your dev-tool idea on 6 weighted criteria — demand signal, distribution path, defensibility, monetization clarity, build cost, founder-market fit. Get a 0–100 score and verdict before committing 6 months.
Demand signal
Reddit threads, GitHub issues, HN comments — are devs already complaining about the gap?
Distribution path
How do potential users hear about it? GitHub trending, HN, niche Slack, your own audience, paid ads?
Defensibility / moat
Network effects, hard data assets, integrations, brand. What stops a clone in 3 months?
Monetization clarity
Who pays? Is the price obvious to the buyer? Is the budget already there or net-new spend?
Build cost vs your skills
Can you ship a v1 in 8 weeks given your current skills + free time? Or does it need 6 months of full-time?
Founder-market fit
Do you actually live the problem daily? Building dev tools you don’t use yourself fails most often.

Promising — validate further before committing
Weights reflect failure-mode patterns from public dev-tool post-mortems. Adjust mentally for context — solo founders should weigh build-cost higher; well-funded teams can weigh defensibility higher.

What it does
Score your dev-tool idea on six weighted criteria — the failure-mode pattern from public dev-tool post-mortems on r/MachineLearning, Hacker News, and Indie Hackers. Output is a 0–100 score plus a verdict band telling you whether to ship, validate further, fix specific weak criteria, or pick a different idea entirely.
Pairs with our CLI DX checklist (build the right way once you commit) and salary estimator (career framing).

- Name the idea concretely (e.g. 'Postgres query plan visualizer for migrations').
- Score each criterion 1-5 with real evidence (links, customer quotes, your own pain).
- Read the verdict band — proceed / validate further / fix weak criteria / pick another idea.
- Export to share with collaborators or revisit in 30 days.
Frequently asked questions
- How do I know if my developer tool idea is worth building?
- The four signals that matter most: (1) demand — devs already complaining publicly, (2) you live the problem daily, (3) you can ship a v1 in 8 weeks given your skills, (4) there's a clear paying buyer or the audience is large enough for a sustainable open-source brand. The scorecard formalizes this.
- Why is 'distribution' weighted so high?
- Most dev-tool failures aren't 'bad product' — they're 'product nobody hears about.' If your only distribution plan is 'tweet about it,' that's a 1. If you have an existing dev audience, niche Slack, or a clear HN/Reddit angle, that's a 4-5.
- Should I build if I score below 60?
- Only if you can fix the weak criteria first. A low demand-signal score means do customer-discovery interviews. A low distribution score means write content for 3 months before launch. A low monetization score means rethink the buyer.
