About this appAI proposal
Plainlight is a RAW photo workflow that runs as an installable web app in a Chromium-based browser on Linux. Open a folder of RAW files, cull, rate, edit with layers and masks, and export, with edits stored in sidecar files next to your originals.
It is built for working and serious amateur photographers on Linux, including Fedora with Wayland, who find Darktable's workflow hard to follow and cannot rely on Capture One or DxO PhotoLab through Wine. The screens follow the order of a shoot: import, cull, edit, deliver.
Because it is a PWA, there is no distro package to match and nothing to emulate. Colour management is the hard part: Plainlight reads the display profile the browser exposes and says plainly when it cannot match your calibrated screen.
- Tagline
- A RAW workflow for Linux, in the order you shoot.

- Why this name
- Plain light is what a photographer wants to see: an honest, uncoloured preview. The name also signals a plain, uncluttered workflow.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Shoot-ordered workflow
Import, cull, edit and deliver as four clear stages, so you always know what is left to do in a session.

Fast culling
Full-screen compare, keyboard-only rating and flags, and a pick view that hides rejects.
No member yet
Non-destructive sidecar edits
Edits are saved as small files next to your RAWs in a folder you choose. Nothing is locked in a database.

GPU-accelerated editing
Exposure, white balance, curves, colour grading and local masks run on the GPU through WebGPU where the browser supports it.

$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
- Shared outputs. Photographers publish private proof pages to clients, who mark favourites. The page carries a small Plainlight credit that can be turned off on the paid subscription.
- Do they become customers?
- Clients see the page once and are rarely Linux photographers, so few will become buyers. Test whether proof-page visitors who also shoot ever click through and sign up.
- First customers
- Solo professional and serious amateur photographers on Fedora with Wayland, shooting weddings or events, who tried Darktable and went back to another tool or dual-boot.
- Where to reach them
- Hacker News and Linux forums: Post a working demo and ask Linux photographers for their blockers. Offer a trial to those who reply.
- Fedora and Darktable communities: Take part in discussions about workflow pain and share a short demo of culling and colour checks.
- Linux photography YouTubers: Offer free licences for honest reviews of the workflow.
- First milestone
- Ten Linux photographers pay for a year of the first version after a 30-day trial, and at least five use it for a real paid shoot.
Why people already pay for this
- Public claimPhotographers on Linux are willing to pay for professional photo editing software if it worked natively on their platform
- Public claimProfessional photo editing software like Capture One and DxO PhotoLab does not reliably work on Linux even through Wine emulation
- Public claimDarktable, the main free alternative for Linux photographers, has workflow issues that users struggle with
- Public claimThere is demand among Linux users for professional photo editing tools with proper support for modern Linux features like Wayland and color calibration

RisksAI inference
- TechnicalBrowsers may not give an accurate calibrated display profile on Linux and Wayland. If previews cannot be trusted, the core promise of colour-managed editing fails for this audience.
- PlatformFolder access with write permission depends on Chromium. Firefox lacks it, and browser changes could break the workflow.
- TechnicalRAW decoding in WebAssembly may be slow on large files and may not cover all new cameras, which weakens a professional claim.
- CommercialDarktable is free, and the evidence is only public claims that Linux users would pay. Willingness to pay for a browser-based tool is untested.
- Intellectual propertyRAW format handling and camera colour data may carry licence terms. Check the licences of any decoder library used.
