Riverbed is a new app that allows you to manage your personal information the way you want. It allows you to build mini-apps that let you interact with your data the way that works best for you—all without writing any code. And because you can make changes in the same web browser or app that you browse your data in, you can always adjust Riverbed to work the way you need it in the moment.

Riverbed is available on the web and on Apple platforms (iOS, iPadOS, and macOS). There is no charge for accounts. To get started:

  • For the web, go to and create an account.
  • For Apple platforms, download the app for iOS/iPadOS or for macOS, then create an account within the app:

How It Works

Riverbed consists of cards containing fields organized into boards. Think of a card like a physical index card. Each card represents one thing. A card has multiple fields on it, each of which stores a bit of information such as text, a number, or a geographic location. A board is a collection of cards that all have the same fields on them.

Cards are displayed in columns. Each column has a set of rules determining which cards appear in it. For example, for a todo list board you might have one column for available todos, one column for todos deferred until the future, and one for completed todos. Cards can appear in more than one column, and they automatically move between columns as your data changes.

Riverbed's real power comes when you add buttons to your cards. Buttons allow you to automate data changes to your cards. For example, on a todo board you might have one button to mark a todo as complete and another button to defer it until tomorrow. Buttons can be configured to be visible or hidden based on data on the card, so that the button only appears in situations where it makes sense.

For some Riverbed boards, just adding a few fields is enough. But the most powerful Riverbed boards have buttons that move your cards through different situations, causing them to appear in different columns. Once you've set this up, you've effectively created your own custom app with no programming—and you can add new features to it at any time when an idea strikes you!


Please let me (Josh) know what you think of Riverbed: questions you have, bugs you run across, and features you would like to see! You can use any of the following channels:

Learning More


There are lots of ways to extend Riverbed, especially if you have software development experience:

  • You can configure one of your boards to receive URLs shared from other apps on iOS and iPad
  • A webhook interface allows you to build up a web service that is informed when a card is created or updated. You can return modified values to save onto the card
  • The clients and server communicate over a simple inspectable JSON-based REST API. You can integrate it with other services via HTTP calls, build alternate frontends on any platform using any technology, or even an alternate backend
  • You can run your own copy of the frontends or backend and make tweaks to the code that work for you
  • You can contribute your tweaks to the main Riverbed codebase. Pull requests are welcome!

The Vision

The conviction behind Riverbed is that everybody should be able to create interactive experiences on the platforms they use every day. You should not be limited to storing only the kinds of data that professional software developers have created an app for, and only managing it in the way they want to—you should be free to manage what you like. And doing so shouldn't require giving up your data to advertising companies to track you.

Riverbed is inspired by past software systems that make it easy for users to change their software in the same environment they use it in, such as HyperCard and Smalltalk.

The goals of the Riverbed project are:

  • Efficiency: minimizing the effort required to create software to manage any kind of data.
  • Usability: providing a user experience on the web and Apple platforms that is as good as if you were using an app that was custom-built for your needs.
  • Simplicity: finding the smallest number of features that unlock the most possibilities.
  • Access: freeing users’ data from platforms that are proprietary, closed, and engage in user surveillance.
  • Permanence: ensuring the platform will remain available in the face of technology changes, maintainer turnover, and independently of corporate interests.

Why the name "Riverbed"? The stones on a river bed aren't planned and designed in advance. As the river flows over the stones constantly every hour of every day, the rough edges are worn down. Small changes result in a stone that is completely unique, formed by the forces of the spot where it lay. A river bed is not formal or ideological: it is simple and natural.

Future Plans

Today Riverbed is a great platform for setting up ways to track your personal information. In the future, I have several ways I’d like to extend Riverbed, depending on community interest:

  • Expanding the list of supported data types, including multimedia
  • Ability to grant access to view or edit your data to individuals or to anyone. (Note that the main focus of Riverbed is your personal information; it is not mainly about team collaboration, so this will be a secondary use case.)
  • Ability to make “board templates” available to share with others, so that you can easily use and remix the boards others have set up.

Answers to Questions


Riverbed is available as a hosted app at Accounts for users are currently free with no limits on amount of data. In the future I plan to offer an optional way for users to donate to help cover server and development expenses.

Riverbed can also be hosted on your own servers. The backend API and frontend clients (web and Apple platforms) are all available under open source licenses, meaning that you have access to the same code I do. You can host your own server to have full control over your data and hosting costs.

Riverbed is not looking to become a business and is not funded by venture capital. I do not have plans to monetize for profits. If the service gets popular enough that server costs become an issue, I may introduce limits for users who join after that time, and existing users with especially high amounts of data may be capped.


If you put all your personal information into Riverbed, how can you trust that the app will stay around?

I (Josh, the creator of Riverbed) plan to keep Riverbed running indefinitely because I rely on it for tracking all my most important personal information. I have over twenty different “boards” (types of information) that replace my use of both third-party apps and specialized custom apps I've built in the past.

But you don't have to trust me: if I do stop maintaining Riverbed someday, you have options. Your data can be exported to JSON format using the same API calls that the frontend apps make (this will be documented as part of pre-public-release documentation efforts). Or, you can host your own installation of Riverbed. The code is released under open-source licenses—AGPLv3 wherever possible, to ensure the source can't be taken away.

A Note on Security

Riverbed uses industry-standard security practices such as encrypted HTTPS traffic and authentication using cryptographically-secure password hashing. Your data is not encrypted at rest in the database.

Like most software licenses, the licenses that the parts of Riverbed are released under includes language disclaiming warranty and limiting liability. Please see the licenses for details.
