📈 wakapi

A minimalist, self-hosted WakaTime-compatible backend for coding statistics

If you like this project, please consider supporting it 🙂. You can donate either through buying me a coffee or becoming a GitHub sponsor. Every little donation is highly appreciated and boosts the developers' motivation to keep improving Wakapi!

👀 Demo

🔥 New: There is a hosted demo version available now. Go check it out! Please use responsibly.

To use the demo version set api_url = https://apps.muetsch.io/wakapi/api/heartbeat. However, this hosted instance might be taken down again in the future, so you might potentially lose your data ❕

⚙️ Prerequisites

On the server side:

• Go >= 1.13 (with $GOPATH properly set)
• gcc (to compile go-sqlite3)
  • Fedora / RHEL: dnf install @development-tools
  • Ubuntu / Debian: apt install build-essential
  • Windows: See here
• Optional: A MySQL- or Postgres database

On your local machine:

• WakaTime plugin for your editor / IDE

⌨️ Server Setup

Run from source

1. Clone the project
2. Copy config.default.yml to config.yml and adapt it to your needs
3. Build executable: GO111MODULE=on go build
4. Run server: ./wakapi

As an alternative to building from source you can also grab a pre-built release. Steps 2, 3 and 5 apply analogously.

Note: By default, the application is running in dev mode. However, it is recommended to set ENV=production for enhanced performance and security. To still be able to log in when using production mode, you either have to run Wakapi behind a reverse proxy, that enables for HTTPS encryption (see best practices) or set security.insecure_cookies to true in config.yml.

Run with Docker

docker run -d -p 3000:3000 --name wakapi n1try/wakapi

By default, SQLite is used as a database. To run Wakapi in Docker with MySQL or Postgres, see Dockerfile and config.default.yml for further options.

🔧 Configuration

You can specify configuration options either via a config file (default: config.yml, customziable through the -c argument) or via environment variables. Here is an overview of all options.

YAML Key	Environment Variable	Default	Description
env	ENVIRONMENT	dev	Whether to use development- or production settings
app.cleanup	WAKAPI_CLEANUP	false	Whether or not to clean up old heartbeats (be careful!)
app.custom_languages	-	-	Map from file endings to language names
server.port	WAKAPI_PORT	3000	Port to listen on
server.listen_ipv4	WAKAPI_LISTEN_IPV4	127.0.0.1	Network address to listen on
server.base_path	WAKAPI_BASE_PATH	/	Web base path (change when running behind a proxy under a sub-path)
security.password_salt	WAKAPI_PASSWORD_SALT	-	Pepper to use for password hashing
security.insecure_cookies	WAKAPI_INSECURE_COOKIES	false	Whether or not to allow cookies over HTTP
db.host	WAKAPI_DB_HOST	-	Database host
db.port	WAKAPI_DB_PORT	-	Database port
db.user	WAKAPI_DB_USER	-	Database user
db.password	WAKAPI_DB_PASSWORD	-	Database password
db.name	WAKAPI_DB_NAME	wakapi_db.db	Database name
db.dialect	WAKAPI_DB_TYPE	sqlite3	Database type (one of sqlite3, mysql, postgres)
db.max_conn	WAKAPI_DB_MAX_CONNECTIONS	2	Maximum number of database connections

💻 Client Setup

Wakapi relies on the open-source WakaTime client tools. In order to collect statistics to Wakapi, you need to set them up.

1. Set up WakaTime for your specific IDE or editor. Please refer to the respective plugin guide
2. Make your local WakaTime client talk to Wakapi by editing your local ~/.wakatime.cfg file as follows

api_url = https://your.server:someport/api/heartbeat`
api_key = the_api_key_printed_to_the_console_after_starting_the_server`

You can view your API Key after logging in to the web interface.

🔵 Customization

Aliases

There is an option to add aliases for project names, editors, operating systems and languages. For instance, if you want to map two projects – myapp-frontend and myapp-backend – two a common project name – myapp-web – in your statistics, you can add project aliases.

At the moment, this can only be done via raw database queries. For the above example, you would need to add two aliases, like this:

INSERT INTO aliases (`type`, `user_id`, `key`, `value`) VALUES (0, 'your_username', 'myapp-web', 'myapp-frontend');

Types

• Project ~ type 0
• Language ~ type 1
• Editor ~ type 2
• OS ~ type 3
• Machine ~ type 4

🔧 API Endpoints

The following API endpoints are available. A more detailed Swagger documentation is about to come (#40).

• POST /api/heartbeat
• GET /api/summary
  • string parameter interval: One of today, day, week, month, year, any
• GET /api/compat/v1/users/current/all_time_since_today (see Wakatime API docs)
• GET /api/compat/v1/users/current/summaries (see Wakatime API docs)
• GET /api/health

⤴️ Prometheus Export

If you want to export your Wakapi statistics to Prometheus to view them in a Grafana dashboard or so please refer to an excellent tool called wakatime_exporter.

It is a standalone webserver that connects to your Wakapi instance and exposes the data as Prometheus metrics. Although originally developed to scrape data from WakaTime, it will mostly for with Wakapi as well, as the APIs are partially compatible.

Simply configure the exporter with WAKA_SCRAPE_URI to equal "https://wakapi.your-server.com/api/compat/wakatime/v1" and set your API key accordingly.

🏷 Badges

We recently introduced support for Shields.io badges (see above). Visit your Wakapi server's settings page to see details.

👍 Best Practices

It is recommended to use wakapi behind a reverse proxy, like Caddy or nginx to enable TLS encryption (HTTPS). However, if you want to expose your wakapi instance to the public anyway, you need to set server.listen_ipv4 to 0.0.0.0 in config.yml

⚠️ Important Note

This is not an alternative to using WakaTime. It is just a custom, non-commercial, self-hosted application to collect coding statistics using the already existing editor plugins provided by the WakaTime community. It was created for personal use only and with the purpose of keeping the sovereignity of your own data. However, if you like the official product, please support the authors and buy an official WakaTime subscription!
