Business ideas for developers
Developers get pitched a lot of agencies that are really sales jobs with a GitHub account. This hub leaves those out. An idea has to list tech as a skill, sit at technical depth 2 or 3, and be a software product: a micro SaaS, app, plugin, subscription tool, or developer product. The team is solo or small, the startup estimate is $15,000 or less, and the week is 32 hours or less. 172 ideas qualify.
Ranking favors a narrower tool, a solo build, and a lower estimate over a platform that needs a team before the first user. Near-duplicate plugins and apps are capped so one archetype cannot take every slot. These 12 are the spread: utilities and plugins you can scope, plus a few larger product shapes that still clear the budget and hour gates.
The figures are the catalog's planning estimates, including Micro SaaS at $3,000 and 20 hours a week. They are not a forecast of MRR. If you would rather sell implementation to businesses than ship a product, the engineers page puts those services back. Use the assessment to re-rank these for you around the problem you already understand.
172 catalog ideas match these rules. 12 are ranked below. Startup costs and weekly hours are preliminary estimates, not quotes or income claims.

Questions about this list
Which developer ideas are excluded?
Client services such as agencies, freelance delivery, and local services are excluded, even when they use technical skill. So are products modeled above $15,000 to start, above 32 hours a week, or with a team larger than a small group. Those ideas remain in the library.
Why are many micro SaaS ideas missing from this shortlist?
The catalog models 172 qualifying product ideas, and a large block of them share one plugin archetype with the same preliminary cost and hours. This page keeps 12 distinct product shapes instead of repeating that block.
Is a micro SaaS realistic beside a job?
The weekly estimates on these cards run from the high teens to about 30 hours. Treat that as build-and-support time, not a 5-hour hobby. If your free hours are lower, filter the library or take the assessment before you pick a product to maintain.
Where do the dollar amounts come from?
They are the startup estimates stored on each idea in the Ideas4Business catalog. They are for comparison. They are not quotes, payroll, or a claim about revenue.
