base

Base is an open source Go backend that includes:

• embedded in-memory, SQL and vector databases with realtime subscriptions
• built-in files and users management
• convenient Admin dashboard UI
• and simple GraphQL && REST-ish API
• native Analytics and LLM observability
• deeply with integrated Base AI Platform for hyperscalability day one.

**Use Hanzo App to rapidly iterate and build new apps!

[!WARNING] Please keep in mind that Base is still under active development and therefore full backward compatibility is not guaranteed before reaching v1.0.0.

API SDK clients

The easiest way to interact with the Base Web APIs is to use one of the official SDK clients:

• JavaScript - @hanzoai/js-sdk (Browser, Node.js, React Native)
• Dart - @hanzoai/dart-sdk (Web, Mobile, Desktop, CLI)

You could also check the recommendations in https://docs.hanzo.ai/how-to-use/.

Overview

Use as standalone app

You could download the prebuilt executable for your platform from the Releases page. Once downloaded, extract the archive and run ./base serve in the extracted directory.

The prebuilt executables are based on the examples/base/main.go file and comes with a JavaScript plugin enabled by default which allows to extend Base with JavaScript (for more details please refer to Extend with JavaScript).

Use as a Go framework/toolkit

Base Base is distributed as a regular Go library package which allows you to build your own custom app specific business logic and still have a single portable executable at the end.

Here is a minimal example:

1. Install Go 1.25+ (if you haven't already)

2. Create a new project directory with the following main.go file inside it:

   package main
   
   import (
       "log"
   
       "github.com/hanzoai/base"
       "github.com/hanzoai/base/core"
   )
   
   func main() {
       app := base.New()
   
       app.OnServe().BindFunc(func(se *core.ServeEvent) error {
           // registers new "GET /hello" route
           se.Router.GET("/hello", func(re *core.RequestEvent) error {
               return re.String(200, "Hello world!")
           })
   
           return se.Next()
       })
   
       if err := app.Start(); err != nil {
           log.Fatal(err)
       }
   }
   

3. To init the dependencies, run go mod init myapp && go mod tidy.

4. To start the application, run go run main.go serve.

5. To build a statically linked executable, you can run CGO_ENABLED=0 go build and then start the created executable with ./myapp serve.

For more details please refer to Extend with Go.

Building and running the repo main.go example

To build the minimal standalone executable, like the prebuilt ones in the releases page, you can simply run go build inside the examples/base directory:

1. Install Go 1.25+ (if you haven't already)
2. Clone/download the repo
3. Navigate to examples/base
4. Run GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build (https://go.dev/doc/install/source#environment)
5. Start the created executable by running ./base serve.

Note that the supported build targets by the pure Go SQLite driver at the moment are:

darwin  amd64
darwin  arm64
freebsd amd64
freebsd arm64
linux   386
linux   amd64
linux   arm
linux   arm64
linux   loong64
linux   ppc64le
linux   riscv64
linux   s390x
windows 386
windows amd64
windows arm64

Testing

Base comes with mixed bag of unit and integration tests. To run them, use the standard go test command:

go test ./...

Check also the Testing guide to learn how to write your own custom application tests.

Security

If you discover a security vulnerability within Base, please send an e-mail to security at hanzo.ai.

All reports will be promptly addressed and you'll be credited in the fix release notes.

Contributing

Base is free and open source project licensed under the MIT License. You are free to do whatever you want with it, even offering it as a paid service.

You could help continuing its development by:

• Contribute to the source code
• Suggest new features and report issues

PRs for new OAuth2 providers, bug fixes, code optimizations and documentation improvements are more than welcome.

But please refrain creating PRs for new features without previously discussing the implementation details. Base has a roadmap and I try to work on issues in specific order and such PRs often come in out of nowhere and skew all initial planning with tedious back-and-forth communication.

Don't get upset if I close your PR, even if it is well executed and tested. This doesn't mean that it will never be merged. Later we can always refer to it and/or take pieces of your implementation when the time comes to work on the issue (don't worry you'll be credited in the release notes).
