Heroku Buildpack Tesseract

This package provide a custom Heroku buildpack providing the Tesseract OCR binary and all the required libraries to Heroku apps. Training data for English, Dutch and Finnish language is provided.


The first step consists in allowing your Heroku app to use multiple buildpacks. We use the excellent heroku-buildpack-multi as follows:

  1. add a configuration variable as

    heroku config:set

    or (equivalently) change the default buildpack as

    heroku buildpacks:set https://github.com/ddollar/heroku-buildpack-multi
  2. create a file called .buildpacks inside your app as


    where LANG is the language used by your app (e.g., ruby, python, or nodejs). A complete list of Heroku buildpacks can be found here.
