If there's one thing all coders love, it's stickers. If you've ever gone to a conference, you will have definitely seen loads of laptops covered in various layers of them.

There are multiple ways to get some cool stickers in your hands (or in your computer's lid!). You can often get them at conferences and meetups, and you can also buy some cool packs online, but there's a third way. Sometimes, companies will go crazy and mail you free stickers just for trying out their product, filling a survey, etc. This article aims to be a periodically-updated list of all those free offers, classified by the effort it'd take you to get each:

Effortless

Minimal effort

If you're up for some fun you'll love Twilio's offer. They have made a retro game that teaches you how to use their service, and will send you some stickers if you complete it (and a shirt!). Learn more in their explainer video , and thank them on Twitter if you end up taking the offer.

Here's another fun challenge: Register on DevRant (a rant and joke social network for developers) and post something that gets 30 upvotes to unlock some free stickers . When you get them, thank them directly on DevRant :D

Medium effort

Big effort
