Ready to raise the bar again in real life?

International software development conference for professional developers who care about quality code, solving problems and bettering their practices

« I’m not a great programmer; I’m just a good programmer with great habits. »  - Kent Beck

Never Stop Learning

A conference that doesn’t challenge your pre-conceptions is not a conference worth attending !

Created by developers for developers, NewCrafts is an independent and international event on software development held annually in Paris and Bordeaux.

Because we believe it is not enough for code to work, we want to question the way we develop, how we perceive our profession and craft.

Newcrafts is two days of advanced talks, hands-on labs and open-session spaces accessible all day !

You might also be interested by pre-conference workshops by our renowned speakers on May 23-24. More info here.
