How to start a Accessibility Audits for Open-Source and Self-Hosted Projects business: plan and growth

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 business built on a complaint people already posted in public.No. 056

An owner can start “Accessibility Audits for Open-Source and Self-Hosted Projects” from a complaint people already posted. The offer, in one line: Affordable automated plus expert a11y audits with a prioritized fix plan for low-budget OSS projects. It is for open-source maintainers. Charge a done-for-you service, and test a price at $200 a month or more. Begin in more than one country. Buyers already talk about this in r/selfhosted. One thread gathered 45 votes and 13 replies across Sep 14, 2026 – Oct 14, 2026. Use that room to meet the first twenty buyers. Do not export it, and do not republish the posts. The idea, the evidence, and the market estimate on this page are free to read. Two paid prompts finish the job: one drafts the offer, the price, and a ninety-day calendar; the other drafts a month of conversations and proof. One credit unlocks both. A software specification is not on this site. When the company is the product itself, a single link further down opens the founder library.

Who would pay

Open-source maintainers. Start in more than one country, and charge a done-for-you service, testing a price at $200 a month or more.

The thread above is the public complaint this business can learn from. Verbatim quotes are not invented. Further sources, when a later report adds them, stay with the evidence.

The offer, in our words

An automated + expert accessibility audit service tailored to budget-limited open-source/self-hosted projects, with a clear report and prioritized fix plan.

Score 2.60, Simmering. Pain, willingness to pay, demand, and the gap in current options drive it. We are not scoring how fast you can code.

Market size

An estimate, built from the bottom up: real customer counts × a realistic price. It shows the size of the prize, not a forecast.

TAM Total addressable

$7.5M a year

2,500 projects · 50% of commercially backed open-source and self-hosted projects (assumption)

SAM Serviceable

$2.3M a year

750 projects · projects with a paying sponsor or company

SOM Obtainable in 3 years

$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 confidence · estimated Oct 2026

How we estimated this
  1. Base: 5,000 commercially backed open-source and self-hosted projects (assumption).
  2. Has the problem: 50% (assume half need an accessibility audit a year).
  3. Revenue per project: $3,000 per year (~$3,000 per audit).
  4. Reachable: 30% (projects with a paying sponsor or company).
  5. Three-year capture: 2% of the reachable segment.

TAM is customers with the problem × revenue per customer. SAM is the part a new business can reach. SOM is a cautious three-year share of SAM. The bars use a log scale. A share marked “assume” is our judgment, not a measurement.

There is no public count for this audience, so the base is our assumption. Read it as an order of magnitude.

Questions

How much money do I need to start?

Enough to talk to buyers and deliver the offer once. A service version can start with a written process and a way to take payment. A software version is a larger bet and is not required to test the price. The band to test is $200 and up.

How should I price it?

Test a price at $200 a month or more, charged as a done-for-you service. Raise it after three paid pilots, not before the first conversation.

Where do the first customers come from?

r/selfhosted is the clue. A related thread gathered 45 votes and 13 replies. Show up there, follow the room's rules, and ask for conversations. Do not scrape it.

Do I need to write code?

No. The prompts on this page draft a plan and a month of growth. Code is a later choice. The founder site linked once below is where the build document lives, if you want it.

A separate site sells the agent build document and can build the product. Have this built

A two-week build starts at $10,000 on that site, after a $1,000 scoping fee.
