About
RoboHash is a web service that generates unique robot, alien, monster, cat, human, and gorilla images from arbitrary text inputs such as usernames, email addresses, IP addresses, filenames, or other identifiers. Images are requested by embedding a text string in the URL, for example https://robohash.org/YOUR-TEXT.png, and the service returns a deterministic image based on that input.
The service supports multiple image sets and parameters, including set=set1 through set=set6, output formats such as PNG and JPG, optional background selection with bgset, size control with size=200x200, and Gravatar lookup via gravatar=yes or gravatar=hashed. The page states that the service is free to use and that images may be embedded under the CC-BY license.
- Deterministic image generation from text
- Multiple character sets and avatar styles
- URL parameters for format and size
- Gravatar-based avatar lookup
- Free embedding under CC-BY license
Free Tier Value
This free tier is perpetual and has no stated usage cap, so it’s treated as an uncapped always-free offering rather than something to price against a paid plan. The page explicitly says the service is free to embed under CC-BY, and there’s no sign-up or credit-card friction, so the practical monthly value is best represented as unbounded rather than a dollar estimate.
