Streamdal is an open-source 'Code-Native Data Privacy' solution for running data tasks directly in your application code.

Think of it as a "workflow engine" or a "pre/post data processor" that is executed client-side via WebAssembly in your application code.

It is at least 10x faster, 10x cheaper and 10x easier to operate than traditional data pipelines.

This is what it looks like:

There are major benefits to running pipelines directly within your app:

• Eliminates the need for a separate data pipeline infrastructure
  • Pipelines execute from within your app, using existing compute that your app is already using
• Eliminates the need for a separate data pipeline team
  • No more waiting for the data pipeline team to make pipeline changes
• Is ridiculously fast
  • Streamdal uses Wasm to execute pipelines at near-native speeds
• Is actually real-time
  • Not "near real-time" or "max-30-seconds-real-time" - but actually real-time - data is processed as soon as your app reads or writes data
• And many other reasons

You don't have to install the server, the console or instrument any of your apps to see Streamdal in action. We've got a live demo :)

While the demo is read-only, it will give you a good idea about the capabilities of Streamdal.

The demo showcases real-time:

1. PII detection & masking
2. Schema inference/detection & validation
3. Data extraction & truncation
4. Stream debugging & monitoring
5. Data source and destination visualization & exploration

You can read more about how this is achieved in the "how does it work?" docs.

Getting started consists of two steps:

1. Installing the server, console and their dependencies
2. Instrumenting your code with one of our SDKs

The easiest way to get Streamdal running is via curl | bash:

curl -sSL https://sh.streamdal.com | bash

1. The install script will verify that you have git, docker and docker-compose installed
2. The install script will clone this repo to ~/streamdal
3. The install script will bring up all components via docker-compose

Once done:

🎉 Openhttp://localhost:8080 in your browser! 🎉

You should be presented with a beautiful (but empty) UI! To populate it, we will need to instrument some code. Onto the next section!

For alternative installation methods, check the docs dir.

Once you have installed the server and console, you can begin instrumenting your code.

Instrumentation involves calling our SDKs .Process() method either after your application reads data from somewhere OR before your app is about to write data somewhere.

• Go ━ Example
• Python ━ Example
• Node ━ Example

To see an example of a complete instrumentation, take a look at one of our shim examples or the Go demo client that is bundled with the ./apps/server.

Streamdal consists of three main components:

• Server
• Console
• SDKs

The basic flow is that you install the server and console and wrap any reads or writes in your app with one of our SDKs. Once that's done, you will be able to see the app and the data your app is reading or writing in the console (or use the CLI).

You will also be able to enforce rules on your data (such as "this should be valid JSON", "message should contain a field called foo", "strip all email addresses" and so on).

The Streamdal platform is made up of several components that must all be at specific versions to function properly together.

When running in production, verify versions of the components against this list:

• Check the docs
• Open an issue (note: this repo is archived and may not receive responses)
• Reach out to the founders via LinkedIn (links at the top of this README)

You have control over what we're building - our roadmap is 100% public!
