About this appAI proposal
Mortise is a small toolkit for developers who build interactive pages with plain HTML. It adds reactive attributes to markup, a simple way to write and ship web components, and a CSS layer for tokens and scoped styles. All three parts work together and install from one package.
It is made for solo developers and small teams who want an integrated set of tools but cannot justify a premium suite price. Tiers sit in the double digits, with a one-time license option, so you can pay once and keep building.
Mortise is a proposal. It starts with the three jobs the source thread names: enhancing HTML, building web components and managing CSS. It does not try to replace your framework or your server.
- Tagline
- HTML, components and CSS, joined together at a price you can justify.

- Why this name
- A mortise is the slot in a wood joint. The product joins three parts of front-end work cleanly, and the name suggests craft, not a premium suite.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Reactive HTML attributes
Add state, events and server-driven updates with attributes in your markup. No build step needed to start.
No member yet
Web component builder
Define a custom element in one file with props, slots and lifecycle hooks. Output is standard web components.
No member yet
CSS tokens and scoping
Manage design tokens, scoped styles and themes from one config, and emit plain CSS files.
No member yet
One install, three parts
Behavior, components and styles share one config and one version, so upgrades do not break the pieces.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Visible inside customers’ products. Sites built with Mortise ship its small runtime and, on the Hobby tier, a console badge and a data attribute on the root element. Other developers who inspect the page can see which toolkit it uses.
- Do they become customers?
- Developers who view source are the buyers, so exposure can become paid use. To test: how many Hobby installs upgrade, and whether the badge draws visits to the docs.
- First customers
- Solo developers and freelancers building server-rendered sites with plain HTML who have said that premium suites cost too much.
- Where to reach them
- Hacker News: Post a Show HN with the free tier and a comparison of the three parts in one working demo.
- Developer newsletters: Offer a launch lifetime price to HTML-first and web components newsletters.
- Open-source forums: Answer questions about HTML enhancement and link working Mortise examples.
- First milestone
- Twenty paid Solo or Lifetime licenses within 60 days of launch, from developers outside the founder's network.
Why people already pay for this
- AI inferenceDatastar charges $349 for its tools suite with WebComponent and CSS add-ons

RisksAI inference
- CommercialThe only price evidence is one Hacker News comment and an AI-inferred $349 figure. Demand for a cheaper alternative may be small or unwilling to pay at all.
- TechnicalBuilding a reactive HTML layer, a component system and a CSS tool is a large scope for a small team, and each part must be good enough to replace what developers use.
- CommercialDevelopers often prefer free open-source libraries, so a paid kit needs a clear gain in integration or support.
- Intellectual propertyThe product must not copy the competitor's API, attribute names or code. Compatibility claims need a legal check.
