What to build

Useful software does not need to become a product.

The best small software solves one real problem for one person or a small group. Tarantula gives it a safe place to live.

Team tools

Replace the spreadsheet, status meeting, or awkward SaaS workaround.

Tiny apps that are too specific to become products—and useful because of it.

Move from generated code to a secure, shareable test without a cloud migration.

Durable agents with tools, schedules, budgets, approvals, and an interface.

The small-software test

Good fit

One person or a small team needs it

The workflow is specific to how you work

It needs a real UI, data, permissions, or recurring jobs

An agent can build and maintain it

Probably use something else

A spreadsheet already works well

A single automation step solves it

You are building hyperscale infrastructure

The app needs bespoke infrastructure, strict multi-region controls, or consumer-scale traffic
