Field dossier / What to build
App ideas nobody made up
Every other list of app ideas was invented by someone brainstorming. These 966 were taken from real people describing a problem in their own words — on Reddit, GitHub, Hacker News, Stack Overflow, Trustpilot and the App Store — then scored 0–100 for how strongly they signalled they would pay to fix it.
Each one links back to the post it came from. Read the complaint before you build.
§01
AI and agent app ideas
Problems people hit while building with LLMs and agents — token accounting, runaway CLI spend, evaluation, parsing model output, monitoring across providers. 205 of the gaps below are about AI tooling specifically, and it is the fastest-growing slice because the tooling is newest.

Developer tools and SaaS infrastructure
The largest category in the corpus at 386 gaps. Self-hosting, observability, CI, database operations — problems engineers describe precisely, because they are the ones living with them.

Data and analytics SaaS ideas
Dashboards, pipelines and reporting people are currently doing by hand. Strong micro-SaaS territory: the complaints are narrow and the buyers already pay for something adjacent.

Cybersecurity SaaS ideas
Compliance work, audit evidence and security tooling that teams describe as manual, expensive or unbearable. High willingness to pay, because the alternative is a consultant.

AI automation services to sell
No-code and automation gaps — the shape of work an agency or a solo operator can sell as a service before ever writing software.

Real estate and local operations
Property managers, agents and local service businesses describing the admin that eats their week. Unglamorous, underserved, and the buyers are reachable.

Questions people ask before they build
What app should I build in 2026?
One somebody has already complained about. Every idea on this page started as a real post on Reddit, GitHub, Hacker News, Stack Overflow, Trustpilot or the App Store, and carries a 0-100 commercial-intent score for how strongly the person signalled they would pay. Sort by that score and start at the top of a market you already understand.
Are these app ideas actually validated?
Each one is a real, specific complaint that cleared an editorial gate at commercial intent 70 or above, and it links back to the post it came from so you can read the original. That is evidence of demand, not proof of a business. It rests on first-hand reports rather than corroboration across many sources, and the honest next step is the validation playbook: talk to five people in that market before you write code.
How is this different from a list of startup ideas?
Every other list of app ideas was invented by someone brainstorming. These were taken from people describing a problem in their own words, and each keeps its source link, its market, and a score. You are reading demand that already exists rather than someone's guess about what might sell.
What is a micro SaaS idea, and are any of these small enough?
A micro SaaS is a narrow tool for one specific job, usually built and run by one person. Filter for a high confidence score and a tightly-worded problem: the narrower the complaint, the smaller the build. Many gaps here describe a single missing feature in a tool people already pay for, which is the classic micro-SaaS shape.
Where do the app ideas come from?
Public complaints, bug reports and feature requests across GitHub, Reddit, Stack Overflow, Hacker News, Trustpilot, the App Store, X and niche forums. Sources are collected continuously, classified and scored, then published weekly. Every opportunity links back to its original post.
Can I use these to find AI app ideas specifically?
Yes. The Dev Tools and Data categories are dominated by problems people hit while building with LLMs and agents — token accounting, evaluation, output parsing, monitoring across providers. Those are the sections below labelled AI and agent tooling.
Pick one and check it properly
Every gap opens to its own page with the complaint, its market and how it ranks in its category — no account needed. The full dossier adds the source links, an MVP scope, suggested pricing, the competitors already there, the risks, and a validation playbook you can run in an afternoon.
