Get more from Software licence compatibility
Software licence compatibility makes it easier to look up software license information without scanning a long reference list manually. The tool exposes license permissions, conditions, and limitations alongside a compatibility indicator based on its supported rule set. Start with a specific name, code, or distinctive term, then compare the returned entry with the exact field your application expects. Read the full license text, retain required notices, and distinguish SPDX expression matching from a complete legal compatibility analysis. A lookup is most useful when you record both the displayed value and the convention behind it, since similar-looking labels can represent different kinds of information. License compatibility depends on the exact licenses, versions, exceptions, and the way software is combined or distributed. This reference is not legal advice or a definitive compliance determination. Use the example below as a starting point and narrow the search if several entries look plausible. Before reusing a result, check that the selected entry matches the intended context rather than choosing only the first familiar-looking label.

How to use this tool
- Enter a name, code, or keyword relevant to software license information. Use a distinctive term to avoid an unnecessarily broad result list.
- Review the returned entries and their labels. Read the full license text, retain required notices, and distinguish SPDX expression matching from a complete legal compatibility analysis.
- Compare the selected entry with the original source or the requirements of the receiving application. Similar names do not always mean interchangeable values.
- Copy the required field together with its context. License compatibility depends on the exact licenses, versions, exceptions, and the way software is combined or distributed. This reference is not legal advice or a definitive compliance determination.

A worked example
MIT
The MIT license entry and its listed permissions, conditions, and limitations
The entry helps locate the obligations to review. A compatibility indicator is only a preliminary aid for a specific license combination.
Match the exact license expression
Version numbers and qualifiers such as only or or-later can change the relevant permissions. A package may also contain multiple components under different licenses or a separately granted exception. Record the exact license expression and preserve notices before using a compatibility summary. How code is linked, modified, or distributed is part of the review and cannot be inferred from two dropdown selections.
Permissions do not erase conditions
A license may permit commercial use while requiring notices, source availability, or other conditions when software is distributed. Read permissions and obligations together instead of treating one favorable label as the entire license. A compatibility indicator also depends on the exact license expression and supported matching logic. Use it to organize a review, then read the applicable license texts and the facts of the intended combination.
When this tool is useful
- Inspect dependency license metadata with a clear reference convention.
- Compare stated license conditions by comparing the available fields.
- Prepare a license-review checklist using a reproducible search term.
Tips for a better result
- License compatibility depends on the exact licenses, versions, exceptions, and the way software is combined or distributed. This reference is not legal advice or a definitive compliance determination.
- Read the full license text, retain required notices, and distinguish SPDX expression matching from a complete legal compatibility analysis.
- Keep the original label alongside the selected code or reference while preparing an import. This makes mismatches easier to investigate later.
Frequently asked questions
Does a positive compatibility result mean I can ignore license conditions?
No. Compatible components can still impose notice, source-disclosure, patent, or other obligations. Review each applicable license and the particular use, and seek qualified advice when a consequential legal decision depends on the answer.
Why can several results appear relevant?
A short search term can match different names, identifiers, or descriptions. Read the full entry and the meaning of the requested field before selecting a value; similarity in spelling is not a reliable equivalence test.
How should I check the value before using it?
Match the result to the receiving system’s expected convention. Read the full license text, retain required notices, and distinguish SPDX expression matching from a complete legal compatibility analysis. For decisions that depend on current authoritative data, verify against the relevant primary reference rather than assuming a bundled list updates automatically.
