Our Community Logo
For events and content built by the LangChain community. Please do not use as a substitute for the official LangChain logo.
Do’s and dont’s
Do’s
Anchor the lockup to a page or frame's edge margins, keeping full clear space on all sides — roughly the height of the mark itself.
Keep the mark and wordmark at their locked proportions, sizes, and spacing.
Pair each mark with its own wordmark — the LangChain mark with LangChain, the LangSmith mark with LangSmith.
Use the light and dark variants as provided, rather than recoloring for a specific background.
Don’ts
Don't stretch or wrap the logo.
Don't use the logo in off-brand colors.
Don't apply effects to the logo — this covers outlining it and resizing or repositioning its elements.
Don't place the logo on a background that doesn't give it enough contrast or clear space.
Don't use the Community logo in place of the official LangChain logo, or in a way that implies LangChain runs a community-organized event or piece of content.
