The PainHunt Blog
Guides on validating startup ideas, honest tool comparisons, and data-backed opportunities — drawn from the real complaints founders usually never see.
How to detect ReDoS vulnerabilities before deployment
Regular expressions that pass code review and every test can still take a service to 100% CPU under a crafted input. PainHunt data shows a gap between the linters that flag patterns and the tooling teams actually need.
Offline budget apps that work without an account
A forced sign-up screen is the most common reason a budget app gets uninstalled before it is ever used. PainHunt data shows 1,117 high-scoring signals in personal finance, and the loudest ones never got past the first screen.
How to track Meta ad set and creative data in HubSpot
Meta Lead Ads deliver the lead but not the ad set or creative that produced it. Teams end up reporting cost per lead at campaign level while paying for creative-level decisions. PainHunt data shows where the wedge is.
How to enforce commit rules that --no-verify can't bypass
Pre-commit hooks run on the developer's machine, so they run only if that machine cooperates. CI flags problems but rarely blocks them. Teams discover the gap during an incident, not before.
Notion alternatives for people who find Notion too complex
The complaint isn't missing features — it's that a note app now takes a tutorial to use, and the simple alternatives are either crippled at the free tier or too small to trust. What 304 app-store-heavy signals actually say.
How to build a metrics hierarchy your team actually acts on
Teams describe a full year of drowning in product data before working out what to track, and dashboards that look good in the meeting and change nothing after. The gap isn't collection — it's the step from number to decision.
How to detect margin erosion before it kills a product
Supplier costs drift up and a winning product quietly stops making money — the sale still shows in revenue, the margin doesn't. What merchants in PainHunt's inventory data say goes wrong, and where alerting would actually catch it.
JWT kid header path traversal: how to stop key ID injection
The JWT kid header gets used as a filesystem path, so ../ in a token reads any file the process can — and leaked signing keys mean full auth bypass. What the reports look like, and what a hardened library owes you.
