It would be great to have logo, to be able to print tshirts and do other things with it.

This page should collect proposals, until we find a good one. Where good means: is a good logo (can be resized, works in one color, etc - search the web for "good logo design" and read a few of the many results) and conveys the idea of the project (eg. should visualize/represent: "one source, several builds, several identical results", but other ideas/messages are certainly possible…).

Also, we actually need to two Logos: one for Reproducible Builds and one for Debian Reproducible Builds, which should probably be the logo plus the swirl :)

ideas / concepts


Taken from slides from Hans-Christoph Steiner's talk about FDrdoid at FOSDEM 16:

idea #1


Using of a circle to represent a build that is reproduced:

  • a circle divided into 3N sectors (= pie chart), where each N consecutive sectors are the same color.
  • 1 color = 1 build
  • N sectors the same color = N builds the same output

idea #8

From reddit request for logos https://www.reddit.com/r/freedesign/comments/59a80v/request_free_software_project_reproducible_builds/d9a3gvr/

A double helix.

Rationale: each strand of the double helix can be used to completely reproduce the other. Also, DNA is somewhat analogous to machine code.

See https://commons.wikimedia.org/wiki/File:DNA_icon.svg (and the category) for a schema of a double helix. (In DNA, the yellow and green rods come in four kinds each, and each kind of green is always paired with the same kind of yellow.)



"drawing hands" -- nerdy M.C. Escher reference, reproducible builds build each other. I don't know how to make it into a proper logo, though.

Suggestion from dkg, hopefully more graphically-inclined people can make it better.


idea #12

baking forms…

by Falko Oldenburg


idea #13

by Falko Oldenburg

baking tetris form…


idea #14

by Falko Oldenburg, who is always reminded of "rabbits" when hearing "reproduction"…


idea #15

by Falko Oldenburg; Some more of that rabbit concept, now constructed from the initials…


"R" and "B" difference by Bernhard M. Wiedemann: https://www.zq1.de/~bernhard/images/rb/rb-diff2.png


Inspired by #8, but all arrows pointing to the right, symbolizing that the same source can be built many times but all builds converge on the same result.

Needs some tweaking visually, but I think this idea can work with and without text, and both at high and low sizes/resolutions.

  • link more existing proposals here
  • actually turn these ideas into actual logos, eg they should work without the text "reproducible builds"


lamby: re: your logos: as said, #7 reminds me too much of the logos of https://en.wikipedia.org/wiki/German_Labour_Front and https://en.wikipedia.org/wiki/Strength_Through_Joy and then i dislike for #7+#8 that they both dont really work without the words reproducible builds". and then they both (to me) symbolize endlessly running in circles, and not many builds results in one result * h01ger likes the _ideas_ of #1, #10 and #11 but i dont consider them ready/suitable as logos _yet_ * h01ger dislikes #2, #4, #5 + #6 - i dont recognize anything in them
