We have used CloudFlare ourselves for many years and have been delighted with the enhanced performance of static content on our website and security benefits (such as DDOS mitigation and the web application firewall) for our APIs and client dashboard. Stripe Billing is a straightforward solution to recurring billing and the developer-friendly API allows us to automate the billing process from start to finish. Postman a great tool for testing APIs. Life without it would be a whole lot more difficult.
We decided to use Laravel as our PHP framework as it is simple to get started with yet a powerful tool featuring database migrations (version control for MySQL ) and compatibility with front end frameworks such as Vue.js as well as its own templating engine, Blade.
Zendesk allows us to provide customer support through virtually any channel, all controlled through one, clean, intuitive interface. Cachet is a free and open source status page system, which is ideal for us as we need to be able to quickly update our customers on server status.
