Combined License of the Animated SVG

Since frameworks.svg is a derivative work incorporating all five logos, the most restrictive compatible terms apply to the combined work.

Governing constraints

Constraint	Source	Impact
Attribution	Angular, React, Vue, Hono	Credit all projects and their respective owners
NonCommercial	Vue.js (CC BY-NC-SA 4.0)	The animated SVG cannot be used commercially
ShareAlike	Vue.js (CC BY-NC-SA 4.0)	Derivatives of the SVG must use CC BY-NC-SA 4.0 or compatible
No modification	Django (trademark)	The Django logo within the SVG must remain unmodified (colors, proportions)
Linking	Django (trademark)	Logo should link to djangoproject.com "wherever technically possible" — not applicable here as the logo cycles within an animated SVG, making a dedicated hyperlink technically infeasible
No endorsement	All (trademark)	Must not imply official affiliation with any project

Effective license for this animated SVG

CC BY-NC-SA 4.0, with additional trademark constraints from Django.

This means:

• Free to share and adapt for non-commercial purposes
• Must give attribution to all five projects
• Derivatives must be shared under the same license
• The Django logo portion must remain unmodified and link to djangoproject.com when possible
• Usage must not suggest endorsement by any of the projects

Risk assessment

Logo	Risk	Notes
Angular	Low	CC BY 4.0 is very permissive
React	Low	CC BY 4.0 is very permissive
Vue.js	Low	Explicitly allows open-source project use
Django	Medium	Trademark-only; animation of the logo could be seen as modification. We use minimal fade-in/out animation only, keeping the logo visually unaltered
Hono	Low	MIT / CC0 — most permissive

Recommendation

The animated SVG is suitable for an open-source demo-apps repository, provided:

1. This LICENSES_LOGOS.md file is kept in the repository for attribution
2. The Django logo is not distorted, recolored, or visually altered (fade-in/out is acceptable)
3. The Django logo links to djangoproject.com when technically possible
4. The repository does not imply official endorsement by any of the five projects

Attribution

• React logo by Meta Platforms, Inc. — CC BY 4.0
• Vue.js logo by Evan You — CC BY-NC-SA 4.0
• Django logo by the Django Software Foundation — Trademark Policy
