Say goodbye to cold, impersonal scheduling links. Use zcal to create beautiful, personalized booking pages that make a great first impression on your guests. It's 100% Free Forever ๐Ÿ”ฅ!

If everyone agrees that scheduling links help save time, then why are they so universally unloved? Today most booking pages present nothing more than a name and a calendar, so as the person receiving the link, the process of booking a time can feel cold and transactional.

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

    Best cloud solution out there

    We moved our services to Render and can't be happier!


Diploi as an Alternative to Render
Render is for developers and teams who need a cloud hosting solution for production applications. You can choose to deploy web services, APIs, background workers, static sites, and databases. Render is a good fit if you require more scalability or separation of concerns, for example, running multiple microservices, dedicated background job workers, or scheduling cron tasks.

  • Cal.com: The Open-Source Calendly Alternative

  • Cal.com: The Open-Source Calendly Alternative
    I've poked around a while ago at some Calendly alternatives (specifically was looking for something that was cheaper than Calendly with most of the basic features).

  • I generated 207 MCP tools from an OpenAPI spec. Generating them was the easy part.

  • Seven Free Node.js Hosting Platforms Worth Trying in 2026
    Render offers a free web service tier for Node applications, with 512 MB of memory and 0.1 CPU, that spins down after 15 minutes of inactivity and cold-starts on the next request. Deploys are Git-driven, native runtimes handle most Node versions without a Dockerfile, one-click rollback works on all tiers, and preview environments are available with their own resource billing. - Source: dev.to / 16 days ago
  • Best alternatives to Heroku in 2026
    Render is the closest structural match to Heroku on this list. It's built around web services, background workers, static sites, cron jobs, and managed Postgres and Redis, which maps almost one-to-one onto a Procfile plus Heroku add-ons. Buildpack-style auto-detection handles most language runtimes without a Dockerfile, and preview environments and one-click rollback exist out of the box. - Source: dev.to / 17 days ago
  • Why Vercel is still my default for shipping frontend projects
    The other limitation is compute. Vercel Functions can handle APIs, server-rendered routes, streaming, and other request-driven tasks, and the current function limits are far more generous. But if your application requires a continuously running background process or custom Docker containers, Vercel isn't the right fit. There are platforms like Render or Northflank that are built for that kind of workload. Vercel... - Source: dev.to / 17 days ago

    A host: A host is really just a computer that stays powered on and connected to the internet with a public address of its own.
