Why switch

Why teams move off Bubble

Self-hosting is not only about saving money. These are the reasons people make the switch.

  • Own your data

    Your data lives on a server you control, not on Bubble's infrastructure. No surprise policy changes and no lock-in.

  • No per-seat pricing

    Open-source alternatives to Bubble are free to run for as many users as your server can handle. A small VPS often costs less than a single subscription.

  • Customize and extend

    Read the code, add plugins, connect it to your own tools and automate it through open APIs. When you need a feature, you can build it or fund it.
