  • grist-core

    Grist is the evolution of spreadsheets.

    Another one for the No-code database category. My new favorite, heard about it on HN a few weeks ago - grist!

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • PostHog

    🦔 PostHog provides open-source product analytics that you can self-host.

    Posthog[1] is an excellent alternative to Google Analytics that should be in that list.



    ONLYOFFICE Document Server is an online office suite comprising viewers and editors for texts, spreadsheets and presentations, fully compatible with Office Open XML formats: .docx, .xlsx, .pptx and enabling collaborative editing in real time.

    I'm surprised office software are not mentioned. To Google Docs Editors / Office 365, an alternative could be ONLYOFFICE. Their word processor, spreadsheet etc work both online and as desktop software, high compatibility with MS formats, and they have a free personal tier and also business plans. I'm not affiliated, just a happy user. And they're EU based!
