How to Use Open Source License Generator — Create MIT, Apache, and GPL Licenses
How to Use the Open Source License Generator:
Step 1: Choose a License
Click any of the 10 license cards to select it:
- MIT — Short and permissive. Allows anyone to use, copy, modify, and distribute your code with minimal conditions. The most popular license on GitHub.
- Apache 2.0 — Permissive like MIT but adds an explicit patent grant, protecting users from patent claims by contributors.
- GPL v3.0 — Copyleft license. Anyone who distributes your code or a derivative must release it under GPL v3.0 too. Ensures derivatives stay open source.
- LGPL v2.1 — A weaker copyleft aimed at libraries. Lets proprietary software link against your library without requiring the whole application to be open source.
- ISC — Functionally equivalent to MIT but shorter. Commonly used by Node.js ecosystem packages.
- BSD 2-Clause — Permissive license requiring attribution. Simpler than BSD 3-Clause.
- BSD 3-Clause — Like BSD 2-Clause but adds a non-endorsement clause, preventing use of your name to promote derivative products.
- MPL 2.0 — File-level copyleft. Only the files under MPL must stay open; the rest of the project can be proprietary.
- Unlicense — Dedicates your work to the public domain. No attribution required, no restrictions whatsoever.
- CC0 1.0 — Creative Commons public domain dedication. Waives all copyright globally to the extent permitted by law.
Step 2: Enter Your Details
- Author / Copyright Holder — Your full name or your organisation name. This appears in the copyright line.
- Year — Defaults to the current year. You can change it to the year the project started, or a range like "2020–2025".
The license output updates in real time as you type.
Step 3: Copy the License
- Copy LICENSE Text — Copies the plain text ready to paste into a file named
LICENSEorLICENSE.txtat the root of your repository. - Copy as Markdown — Copies the license wrapped in a Markdown code block with a ## License heading, ready to paste into your README.
Tips
- For The Unlicense and CC0, the author and year fields are not used — the output is the same for everyone.
- GitHub automatically detects the license type when you name the file
LICENSE(no extension) and it matches a known SPDX identifier. - If your project started before the current year, you can write a year range: "2021–2025".
- For Apache 2.0 projects, the recommended practice is also to add a
NOTICEfile listing third-party attributions.

Use Tool →JSON to Zod — Schema Generator
Generate Zod validation schema code from a JSON sample object. Infers z.string(), z.number(), z.boolean(), z.array(), z.object(), and z.null() types automatically. Handles nested objects, arrays of objects with optional field detection, and outputs copy-ready TypeScript with import and z.infer type alias.
Use Tool →JSONL Formatter — Line-by-Line Validator
Format, validate, and inspect JSON Lines (JSONL) and NDJSON files. Validates each line individually, reports parse errors by line number, outputs compact JSONL or a pretty-print preview, and lets you download the cleaned file.
Use Tool →TLS Cipher Suite Checker — Strength Analyzer
Check TLS protocol version compatibility and cipher suite strength ratings against current best practices. Supports IANA and OpenSSL cipher names — rates each suite as Strong, Weak, or Deprecated and explains why.
Use Tool →Password Entropy Calculator — Crack Time Estimator
Calculate the information-theoretic bit entropy of any password or API key. Detects character set pools automatically, shows the total number of possible combinations, and estimates crack time across five attack scenarios from rate-limited web logins to GPU cracking clusters.
