trolls.dev
An independent software studio Working while the world sleeps

Small, useful software, built through the night.

We're a tiny product studio that designs, builds, and runs its own software. Our trolls work while the world sleeps — so you wake up to useful things.

Almost everything we “built” was deciding what to leave out. The bet behind it
03 The map — case study

Thyseus

Live object detection & GPS mapping from public cameras.

A community-powered platform that turns public traffic-camera feeds into a live map. Detection runs right in contributors’ browsers, and every spotted vehicle, person, and piece of infrastructure lands on the shared map with computed GPS coordinates.

Every open browser tab is a sensor. Together, they’re a map. The bet behind it
04 The lab — case study

AI User Interviews

User research at the speed of AI.

Run a hundred-plus user interviews a week with hyper-realistic AI interviewers — no calls to schedule, no sessions to moderate, no notes to take by hand — and read the synthesized findings while the question still matters.

Live Web AI-moderated
The bottleneck was never the questions — it was the calendar. The bet behind it
05 The workbench — case study

code-results

See the impact of your code on your business.

A tool that traces the line from the code a team ships to the numbers the business actually watches — sign-ups, activation, revenue — so the people who wrote a change are the first to see whether it worked.

Live Web Code → impact
Every deploy is a hypothesis. The business is where it’s proven. The bet behind it
06 The inspector — case study

Preflight

Check your PDF before it flies.

A native macOS utility that checks a PDF against exact submission limits — byte size, page count, searchable text, encryption — and safely optimizes it to fit. The original is never touched; nothing leaves your Mac.

Editor's note

We stay up late

trolls.dev is deliberately tiny. No investors to impress, no meetings about meetings — just a small crew that designs, builds, and runs its own products. Like our industrious mascots, we do our best work while the rest of the world sleeps.

The house rules

Three of them, and always in this order.

  1. 01

    Plan

    Troll mascot writing plans

    Every product starts as something we wanted for ourselves. If we wouldn't use it every week, we don't build it.

  2. 02

    Ship

    Troll mascot hard at work

    Small releases, shipped often. A useful thing in your hands today beats a perfect thing that never launches.

  3. 03

    Profit

    We run what we ship for the long haul — fast, ad-free where it counts, and respectful of your attention.

There's more to the story — the six principles we work by and how this site is made.

Engineering

The camera moved, the world didn't

The simplest way to find motion in a video is to subtract one frame from the next: whatever changed, moved. It works beautifully until the camera itself moves — a traffic cam pans, a webcam gets bumped, wind leans a pole — and then everything changed, so by that logic everything moved. The whole frame lights up and the one car actually crossing the intersection is lost in a field of false alarms. Thyseus reads public cameras it doesn't control and can't hold still, so before it can trust that something moved, it has to work out how much of the change was the world and how much was the lens. The fix is to measure the camera's own motion first, cancel it, and only then ask what's left.

Q & A

The short interview

Q. What is trolls.dev?

A.

trolls.dev is a small, independent software studio (trolls.dev LLC) that designs, builds, and runs its own products. It's deliberately tiny — a small crew shipping small, useful software, with no outside investors.

Q. Does trolls.dev do client work or contracting?

A.

No. trolls.dev only builds and operates its own products — no agencies, no client work, no handoffs. Everything the studio ships, it runs for the long haul.

Q. What products does trolls.dev make?

A.

Five products are live today, each designed, built, and run by the studio: ganttchart.ai, an AI-powered Gantt chart generator that turns a plain-English project description into a shareable, editable timeline in seconds; DReader, a clean, ad-free, mobile-optimized reader for DrudgeReport.com; Thyseus, a community-powered platform that turns public camera feeds into a live map of detected vehicles, people, and infrastructure, with detection running right in the browser; AI User Interviews, which runs user-research interviews with hyper-realistic AI interviewers so findings arrive in days, not weeks; and code-results, which traces the code a team ships to the business numbers it moves. A sixth, Preflight — a native macOS utility that checks a PDF against exact submission limits and safely optimizes it to fit — is on its way to the Mac App Store.

Q. Is trolls.dev venture-backed?

A.

No. The studio is independent and self-funded, with no investors to impress. That's a deliberate choice: it keeps the products small, focused, ad-free where it counts, and respectful of your attention.

Q. How can I get in touch?

A.

Email [email protected] or use the contact form on this site. Whether it's feedback on a product, a bug you spotted, or just a hello — the trolls read every message.

Correspondence

Letters to the editors

rite to us. Feedback on something we shipped, a bug you caught in the wild, a product we ought to build, or plainly a hello — every letter lands on the same desk the products come off, and a troll reads each one by hand. No queue, no ticket number, no chatbot standing at the door.
