Update 14-08-2019: Greenlock is awesome but needs support. If you don't want to code this yourself consider donating $100 or so on their indiegogo page so they can ship Greenlock v3 and stay compatible with the Let's Encrypt API. Recently I pushed a long overdue feature for Checkly: SSL for…
Something different this week. I got an email from an aspiring SaaS bootstrapper. Let's call him John. John explained his working situation at a tech startup and his dream to start a SaaS in the cloud security space by himself. He also had some pretty good questions. I asked John…

Over the last year or so, I experimented with different ways of getting customer feedback for Checkly. This post is about what worked for us and how I was totally wrong about chat widgets. We'll look at some common tools like Hotjar, Drift, SurveyMonkey, straight up email and even Github.…

More specifically, we'll dive into: Refactoring the existing Hapi.js based APIAPI key based authenticationRefactoring models with Objection.jsValidating…
This is a short follow up to last week's story on Stripe Billing as a reader on Hackernews commented that it seemed we didn't handle VAT. We do, but I just left it out of the story. Update 25-04-2019: Stripe just released a big update to their Billing product that…
