Useful software.Open notebook.

Small tools for real problems.
The work behind them, in public.

I build small tools around everyday friction. Start with something useful. See if people use it. Then decide what comes next.

The product index.

What you can use today,
and what is still taking shape.

02 / THE LAB, IN PUBLIC

A record of the work.

Small experiments still deserve
an honest record.

No verified usage or financial figures have been published.

Figures for each project. Usage units differ by product and are not added together.
Project / status Use Purchases Revenue · EUR
MANUALLY MAINTAINEDHow to read these numbers
What counts, what doesn’t, and what’s missing

Data not yet available means there is no verified figure for the stated period. It does not mean zero. Not applicable means the product has no paid offer in this version.

Use
Completed study sessions in OpenTests; reports from users’ own Jira exports in StepBudget. These are actions, not unique people. Product-specific sources and exclusions appear below.
Purchases
Successfully paid orders completed during the period, including orders later refunded. Excludes test, failed and cancelled payments. One person may make several purchases.
Revenue · EUR
Customer payments received during the period, excluding tax, minus refunds recorded in that period. Before payment fees and operating costs. This is not profit. One-off generation payments are not monthly recurring revenue (MRR).
Coverage and dates
The period is fixed, not a rolling “this month” counter. A source and verification date accompany every published number. Partial or observed samples are labelled; missing projects are never silently counted as zero.

Updates are entered after checking an aggregate report or a documented observation. This page has no live analytics connection and does not collect study material, Jira exports or payment details.

What each project status means
In development
Being built or prepared locally. No public product is implied.
Testing
A real validation test is underway. Results are still being assessed.
Published
A working version is publicly accessible. This does not mean demand or commercial success has been validated.
Closed
The experiment has been explicitly ended. Its notes can stay in the ledger.

03 / HOW I WORK

Enough to help.
Small enough
to finish.

deBarrosLabs is my personal software lab. I want useful experiments to earn their way into independent products.

  1. 01 / START CLOSE TO THE PROBLEM

    Find the actual friction.

    Understand who runs into it and what they do today. A neat idea alone isn’t enough.

  2. 02 / KEEP THE SCOPE SMALL

    Build the minimum useful thing.

    Make one job easier. Add complexity when the product actually needs it.

  3. 03 / LET THE EVIDENCE IN

    Continue, change, or stop.

    Look at real use and feedback. Keep what helps. Be willing to close what doesn’t.

04 / SAY HELLO
