Why trade here

A marketplace that behaves like one

No. I

Updates land under the purchase you already made

Every listing ships as a download carrying a version. When the seller improves it, the new version appears under the same receipt — you do not buy it twice, and the copy you downloaded first does not disappear. Your library is a record, not a snapshot of the day you happened to pay.

No. II

Pay once

That is the whole model.

No. III

Ratings come off receipts

Only buyers can review. Nobody rates their own shelf, and nobody rates a thing they never took home.

No. IV

The maker is behind the counter

A forum for open questions, messages for the specific ones. You are writing to whoever built the tool rather than to a help centre that has never opened it.

No seat counts. No renewal you forget to cancel. No tier hiding the feature you came for.

How it works

Four stepsand none of them a sales call

  1. Open an account

    Buying, selling, or both. Both works from one account.

  2. Walk the shelves

    Browse by category or by tag — the model it targets, the stack it fits, the workflow it belongs to. Every listing says what is in the download before you pay for it, and the reviews under it were left by people who bought the same version.

  3. Buy and download

    Pay once. The current version downloads immediately and a download allowance sits against the purchase; if you run it out on a new machine, the seller can top you up.

  4. Come back for updates

    New versions land under the same receipt.

  5. Open an account

    Prompt Packs

    Tested prompt sets for a job you do often — briefs, reviews, rewrites, the awkward email.

    Coding Agents

    Agent configs, tool definitions and harnesses that drop into a stack you already run.

    TaggedBy stack, by runtime

  • No. 03

    Research

    Finding, reading and summarising at volume.

    TaggedBy source, by output

  • No. 04

    Workflows

    Multi-step chains wired to the tools on your desk — the ones that turn four manual steps into one command, and keep working when the input is messy.

    TaggedBy trigger, by tool

  • No. 05

    Evaluation

    Judges, rubrics and test suites for grading model output.

    TaggedBy metric, by task

  • No. 06

    Utilities

    The small scripts that take the friction out of a long day.

    TaggedOdds and ends

Departments are stocked by sellers, so the list grows as the post does. Everything in them is a download with a person's name on it.

For sellers

Put your work
on the counter

If you built something that saves you an hour a week, it is worth an hour of somebody else's. Set the price, keep the customer, ship when you are ready.

  • Draft privately. Publish when it is ready, not when a review queue says so.
  • Ship a new version without re-listing — buyers keep the purchase they made.
  • Payment lands in your own Stripe account.
  • Answer buyers yourself, and set your own terms on a refund request.

Questions

Before you sign up

  • A download, at a version — prompts, scripts and whatever supporting files the seller packed with them. The listing says what is inside before you pay, and the reviews under it were left by people who bought the same thing.

Post Card

The post is open

Free to join, whichever side of the counter you are on. Bring something to sell or come and see what is on the shelves — it costs nothing to walk in.
