Is spark is the best way to start a project?

Maybe.

I agree with @topvillas. Maybe.

It really depends on the project... If you are going to build a guestbook: No.

Are you going to build a SAAS application with subscriptions? Maybe. If you don't have the skills or time to work on the base of the application then Spark could be a solution.

Let's not forget to mention the ability to learn from spark, if you need to implement it differently spark is maybe not a good starting point. If you want to find out how you can achieve a good starting point spark might be the resource.

I don't own spark myself but I've heard a lot of talk about the fact that you can learn a lot from just reading through it.

@KodeCept Spark isn’t a just a Laravel starter kit, it’s a starter kit—built on Laravel—specifically for subscription-based, “software-as-a-service” (SaaS) apps.

So it really depends on the type of app you’re building. There’s no straightforward “yes” or “no” answer.
