A directory of companies, people, and projects that are Open Source and from Montréal.

Why is there a list combining a licensing model with a geographical location?

Generally, I’ve found that the Open Source community is just that - a community. People who contribute to open source code often do so because they know other contributors personally, they use each other’s code, or they met someone at an event who pointed them to something. You’ll find that a lot of open source projects are city specific - frequent attenders of meetups tend to hear about the same projects, learn about the same companies doing open source, and contribute in the same way.

Montreal is no exception. If you’re interested in Open Source, it’s likely you ended up one day at Notman House. If you’re learning to code, it’s likely you’ve heard of Les Pitonneux. If you’re building an open source business, you might know that Shopify was cofounded by a Quebecois. If you’re a gamer, you might know that Ubisoft’s Prince Of Persia was made here, and that the original source code is on GitHub.

I want to build a list where we can see and learn about each other’s code, just a bit easier, in the open.

osmtl#3 Hacktoberfest special

Let’s kickoff the new season of meetups by diving into #Hacktoberfest! If you haven’t already heard about it, head over to and register to track your progress throughout the month.

Schedule: - 5:00pm Open doors, arrive early to meet the group - 6:00pm Start presentation of the day - 6:30pm Lightning talks

This month we’ll have Kim Noel talking about Open Source!

We’ll go through a kick run down of the history behind Hacktoberfest, an intro to open source and a short demo about contributing – what a documentation contribution looks like, what a code sample contribution looks like, and maybe even checkout some core code contributions! We will also explore what it takes to create a community around your open source project and how to help ensure folks feel safe approaching and contributing to your OSS project.

After this talk, we plan to have lightning talks from the crowd - five minutes each - about open source projects you love or worked on. If you want to present anything just make sure to arrive a bit earlier so that we can get your name on the list.

OSMTL#2 + lightning talks!

Let’s get together along with the group of people already united around to share some ideas and start interesting open source related discussions :)

This month we’ll have Vincent Cloutier sharing his experience working on is getting reborn! is an open-source photo sharing system with undeletable pictures (think of it as the anti-snapchat), that became quite large before overwhelming its creators with stars (900 stars on github), memes (russian), and porn (obviously). Its makers shut it down, but plans to keep things manageable have been devised. Lessons learned by managing a large community of users and developers will be shared, as well as things its creators wished they had known beforehand.

After this talk, we plan to have three lightning talks - five minutes each - about open source project’s YOU are working on. If you’d like to talk briefly about your project, GET IN TOUCH!
