  • simple and beautiful interface
  • multi file pastes
  • accounts
  • good editor
  • a lot of languages
  • tagging pastes
  • private pastes
  • encrypted pastes
  • editing pastes and a full history system
  • simple to use and mostly restriction free REST API


pastemyst also provides a first-party cli tool to interact with pastemyst directly without an interface. you can learn more about pastry from pastemyst/pastry

building and running

to build and run pastemyst you need dmd, dub, libssl-dev (1.1), libscrypt (libscrypt-dev in ubuntu repos), mongodb and pastemyst-autodetect.

on windows libssl should already be installed and libscrypt is prepackaged in lib/windows/scrypt.lib (you can build it yourself from

you also need the diff and patch tools installed to be able to edit pastes and look at the history.

run the mongodb server on and create 2 databases, pastemyst and pastemyst-test (for unit testing).

you also need a config.yaml file at the root of the project. it should look like this.

the github id and secret should be gotten from: github applications, the homepage url should be: http://localhost:5000/ and the authorization callback: http://localhost:5000/login/github/callback; same with gitlab, just replace github with gitlab.

don't forget to first pull the submodules:

git submodule update --init --recursive

now simply run dub run and everything should work fine.


you can run this project with docker.

  • after cloning this project do NOT forget to add the git submodule dependency
  • create a config.yaml file and fill it in; you can copy the config-example.yaml file in the root folder of this project
  • build the docker-compose: make build
  • run the docker-compose: make up
  • open your favorite browser and access localhost:5000

you must run the tests inside the docker. To enter the docker run docker exec -it pastemyst-v2_app_1 sh (by default) in the root folder of the project. however if you change to root project's folder name or run another image this may not work! to access the image do docker ps and then choose the one of the images with app in it's name. now you just run dub test. to exit the docker just run exit.

do not forget to run make down when you're done!

to run it again just do make up and you're good to go!


first find an issue you would like to work on (or create your own and wait for approval). you should work on a separate branch (if you're working on a new feature name the branch feature/feature-name, for fixes: fix/fix-name, etc).

api libraries

here are some api libraries that are developed by other people. they are not directly supported by me. big thanks to the developers! if you want your library added here just open an issue.

link language author supports v2 java Yeff yes
pastemyst-cpp c++ billyeatcookies yes
MystPaste.NET c# shift-eleven yes
pastemystgo go WaifuShork yes
pastemyst.v v billyeatcookies yes
pastemyst-ts ts YilianSource yes
pastemyst-rs rust ANF-Studios yes
pastemyst.js js/ts harshhhdev yes
pastemyst-d d codemyst yes
pastemyst-py python munchii yes
PasteMystNet c# dentolos19 yes
PasteMyst-JS js fmproductions no

you should avoid using a library not supporting the v2 api, since it might break and is lacking a lot of features.
