Every tool here was built to solve a real problem we encountered manufacturing tattoo and piercing products for over 25 years. The gauge converter started as an internal reference. The needle selector grew out of customer questions we answered hundreds of times. The studio CRM exists because we couldn't find one that handled both tattoo and piercing workflows correctly.
All 47 tools are free, require no account, and run entirely in your browser. No data is collected or stored. Use them professionally, embed them in your own site, or fork the source on GitHub.
