Accessibility Audits for Open-Source and Self-Hosted Projects is a startup idea for open-source maintainers. A developer of free Nextcloud Android apps admits accessibility is checked last if at all, and suspects that's true across most of the self-hosted community. A thread in r/selfhosted drew 45 upvotes and 13 comments between Sep 14, 2026 – Oct 14, 2026. People get by with axe DevTools, Lighthouse, and Agency audits, and that still leaves this job open. Hotness is 2.60, Simmering. Mild annoyance. Price-sensitive audience. The thread drew 45 upvotes and 13 comments. Only clumsy or enterprise-only options. A 1-2 week mvp. A first version is weekend-easy, about 2 weeks, priced at $200 a month or more and charged as a done-for-you service. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for Accessibility Audits for Open-Source and Self-Hosted Projects: real customer counts × a realistic price. Not a forecast.
$7.5M a year
2,500 projects · 50% of commercially backed open-source and self-hosted projects (assumption)
$2.3M a year
750 projects · projects with a paying sponsor or company
$45K a year
15 projects · 2% of the reachable segment in three years
What that means
15 projects a year × ~$3,000 = $45K a year in revenue
Low confidenceHow we estimated this
- Base: 5,000 commercially backed open-source and self-hosted projects (assumption).
- Has the problem: 50% (assume half need an accessibility audit a year).
- Revenue per project: $3,000 per year (~$3,000 per audit).
- Reachable: 30% (projects with a paying sponsor or company).
- Three-year capture: 2% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.
No public count exists for this audience, so the base is our assumption. Treat it as a rough order of magnitude.

Is this idea already taken?
People already use axe DevTools, Lighthouse, Agency audits. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 2 weeks (2 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is open-source maintainers. Charge a done-for-you service, and test a price at $200 a month or more. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
