Required Notice: Copyright 2026 Astrit (https://slash.tools)
Slash is offered under the PolyForm Noncommercial License 1.0.0, with the additional terms in Section 2 about commercial use and the Slash name. Section 1 is a plain-English note. Section 2 is the license.
Hi, I'm Astrit, and I make Slash.
You're welcome here. Use Slash in your personal projects, side projects, experiments, coursework and open-source work at no cost. Read the code, take it apart, change it and learn from it. Bug reports, fixes and pull requests are always appreciated, big or small.
Why this license. I want developers to be able to use, try and improve Slash freely when they aren't making money from it. I also need to keep Slash sustainable. That means two things:
- Companies and individuals can't take Slash, clone it, white-label it or resell it for profit without a commercial license.
- The name "Slash" and its logos stay with me, so people always know what the official Slash is. If you fork it, give your fork its own name.
Using Slash commercially. If Slash is going into a product or service that makes money (a paid app, a SaaS product, client work, an internal tool at a for-profit company), you need a commercial license. That's easy to arrange. Email legal@slash.tools with:
- who you are and the company you work for,
- what you're building and where Slash fits in,
- roughly how many people or sites will use it.
I'll get back to you with terms. If you aren't sure whether your use counts as commercial, ask. I'd rather answer a question than have you guess.
Thanks for being here.
Astrit
This note explains the intent behind the license. If it ever seems to differ from Section 2, Section 2 is what applies.
- Noncommercial grant. You may use, copy, modify, distribute and contribute to the software for any noncommercial purpose, as set out in the PolyForm Noncommercial License 1.0.0 (Section 2.4).
- Commercial restriction. Commercial use needs a separate, paid commercial license from the licensor (Section 2.2).
- Trademarks. This license grants no rights to the Slash name, logos or branding (Section 2.3).
- No warranty, no liability. The software comes as is (Section 2.4, "No Liability", and Section 2.5).
The PolyForm Noncommercial License 1.0.0 allows use only for permitted purposes. For clarity, none of the following is a permitted purpose, and each needs a separate commercial license from the licensor:
- (a) using the software, or any change or new work based on it, in or with a product, service, website or application that is sold, licensed for a fee, supported by advertising or subscriptions, or otherwise run to generate revenue;
- (b) offering the software, or any change or new work based on it, as part of a paid service, including hosted, managed, consulting or client services;
- (c) selling, sublicensing, renting or otherwise distributing the software, or any change or new work based on it, for a fee or other commercial advantage;
- (d) white-labeling or rebranding the software, or presenting it as your own product, for a commercial purpose; and
- (e) use by or on behalf of a for-profit company, other than use allowed under "Personal Uses" in Section 2.4.
To ask for a commercial license, email legal@slash.tools. A commercial license is valid only when given in writing by the licensor.
"Slash", the Slash logos, and the names, icons and branding of Slash products (together, the "Slash Marks") belong to the licensor. All rights in the Slash Marks are reserved. This license does not grant any right to use them.
- (a) If you distribute a changed version or a fork of the software, you must give it a name and branding that are not the Slash Marks and are not confusingly similar to them.
- (b) You must not use the Slash Marks in a way that suggests your version, product or service is official, or is made, endorsed, sponsored or supported by the licensor.
- (c) You may use the name "Slash" only in plain text and only to say truthfully where your work comes from, for example "based on Slash". You must keep the Required Notice above.
The text below is the PolyForm Noncommercial License 1.0.0, unchanged. The licensor is Astrit, and the software is Slash, including every package and file in this repository.
