About Cal.diy

Cal.diy is the community-driven, fully open-source scheduling platform — a fork of Cal.com with all enterprise/commercial code removed.

Cal.diy is 100% MIT-licensed with no proprietary "Enterprise Edition" features. It's designed for individuals and self-hosters who want full control over their scheduling infrastructure without any commercial dependencies.

What's different from Cal.com?

• No enterprise features — Teams, Organizations, Insights, Workflows, SSO/SAML, and other EE-only features have been removed
• No license key required — Everything works out of the box, no Cal.com account or license needed
• 100% open source — The entire codebase is licensed under MIT, no "Open Core" split
• Community-maintained — Contributions are welcome and go directly into this project (see CONTRIBUTING.md)

Note: Cal.diy is a self-hosted project. There is no hosted/managed version. You run it on your own infrastructure.

Built With

• Next.js
• tRPC
• React.js
• Tailwind CSS
• Prisma.io
• Daily.co

Getting Started

To get a local copy up and running, please follow these simple steps.

Prerequisites

Here is what you need to be able to run Cal.diy.

• Node.js (Version: >=18.x)
• PostgreSQL (Version: >=13.x)
• Yarn (recommended)

If you want to enable any of the available integrations, you may want to obtain additional credentials for each one. More details on this can be found below under the integrations section.

Development

Setup

1. Clone the repo (or fork https://github.com/calcom/cal.diy/fork)

   git clone https://github.com/calcom/cal.diy.git

   If you are on Windows, run the following command on gitbash with admin privileges:
   > git clone -c core.symlinks=true https://github.com/calcom/cal.diy.git
   

2. Go to the project folder

   cd cal.diy

3. Install packages with yarn

   yarn

4. Set up your .env file

   • Duplicate .env.example to .env
   • Use openssl rand -base64 32 to generate a key and add it under NEXTAUTH_SECRET in the .env file.
   • Use openssl rand -base64 24 to generate a key and add it under CALENDSO_ENCRYPTION_KEY in the .env file.

Windows users: Replace the packages/prisma/.env symlink with a real copy to avoid a Prisma error (unexpected character / in variable name):

# Git Bash / WSL
rm packages/prisma/.env && cp .env packages/prisma/.env

5. Setup Node If your Node version does not meet the project's requirements as instructed by the docs, "nvm" (Node Version Manager) allows using Node at the version required by the project:

   nvm use

   You first might need to install the specific version and then use it:

   nvm install && nvm use

   You can install nvm from here.

Quick start with yarn dx

• Requires Docker and Docker Compose to be installed
• Will start a local Postgres instance with a few test users - the credentials will be logged in the console

yarn dx

Default credentials created:

Email	Password	Role
free@example.com	free	Free user
pro@example.com	pro	Pro user
trial@example.com	trial	Trial user
admin@example.com	ADMINadmin2022!	Admin user
onboarding@example.com	onboarding	Onboarding incomplete

You can use any of these credentials to sign in at http://localhost:3000

Tip: To view the full list of seeded users and their details, run yarn db-studio and visit http://localhost:5555

Development tip

1. Add export NODE_OPTIONS="--max-old-space-size=16384" to your shell script to increase the memory limit for the node process. Alternatively, you can run this in your terminal before running the app. Replace 16384 with the amount of RAM you want to allocate to the node process.

2. Add NEXT_PUBLIC_LOGGER_LEVEL={level} to your .env file to control the logging verbosity for all tRPC queries and mutations.
   Where {level} can be one of the following:

   0 for silly
   1 for trace
   2 for debug
   3 for info
   4 for warn
   5 for error
   6 for fatal

   When you set NEXT_PUBLIC_LOGGER_LEVEL={level} in your .env file, it enables logging at that level and higher. Here's how it works:

   The logger will include all logs that are at the specified level or higher. For example: \

   • If you set NEXT_PUBLIC_LOGGER_LEVEL=2, it will log from level 2 (debug) upwards, meaning levels 2 (debug), 3 (info), 4 (warn), 5 (error), and 6 (fatal) will be logged. \
   • If you set NEXT_PUBLIC_LOGGER_LEVEL=3, it will log from level 3 (info) upwards, meaning levels 3 (info), 4 (warn), 5 (error), and 6 (fatal) will be logged, but level 2 (debug) and level 1 (trace) will be ignored. \

echo 'NEXT_PUBLIC_LOGGER_LEVEL=3' >> .env

for Logger level to be set at info, for example.

Gitpod Setup

1. Click the button below to open this project in Gitpod.

2. This will open a fully configured workspace in your browser with all the necessary dependencies already installed.

Manual setup

1. Configure environment variables in the .env file. Replace <user>, <pass>, <db-host>, and <db-port> with their applicable values

   DATABASE_URL='postgresql://<user>:<pass>@<db-host>:<db-port>'
   

   If you don't know how to configure the DATABASE_URL, then follow the steps here to create a quick local DB

   1. Download and install postgres in your local (if you don't have it already).

   2. Create your own local db by executing createDB <DB name>

   3. Now open your psql shell with the DB you created: psql -h localhost -U postgres -d <DB name>

   4. Inside the psql shell execute \conninfo. And you will get the following info.

   5. Now extract all the info and add it to your DATABASE_URL. The url would look something like this postgresql://postgres:postgres@localhost:5432/Your-DB-Name. The port is configurable and does not have to be 5432.

   If you don't want to create a local DB. Then you can also consider using services like railway.app, Northflank or render.

   • Setup postgres DB with railway.app
   • Setup postgres DB with Northflank
   • Setup postgres DB with render

2. Copy and paste your DATABASE_URL from .env to .env.appStore.

3. Set up the database using the Prisma schema (found in packages/prisma/schema.prisma)

   In a development environment, run:

   yarn workspace @calcom/prisma db-migrate

   In a production environment, run:

   yarn workspace @calcom/prisma db-deploy

4. Run mailhog to view emails sent during development

   NOTE: Required when E2E_TEST_MAILHOG_ENABLED is "1"

   docker pull mailhog/mailhog
   docker run -d -p 8025:8025 -p 1025:1025 mailhog/mailhog

5. Run (in development mode)

   yarn dev

Setting up your first user

Approach 1

1. Open Prisma Studio to look at or modify the database content:

   yarn db-studio

2. Click on the User model to add a new user record.

3. Fill out the fields email, username, password, and set metadata to empty {} (remembering to encrypt your password with BCrypt) and click Save 1 Record to create your first user.

   New users are set on a TRIAL plan by default. You might want to adjust this behavior to your needs in the packages/prisma/schema.prisma file.

4. Open a browser to http://localhost:3000 and login with your just created, first user.

Approach 2

Seed the local db by running

cd packages/prisma
yarn db-seed

The above command will populate the local db with dummy users.

E2E-Testing

Be sure to set the environment variable NEXTAUTH_URL to the correct value. If you are running locally, as the documentation within .env.example mentions, the value should be http://localhost:3000.

# In a terminal just run:
yarn test-e2e

# To open the last HTML report run:
yarn playwright show-report test-results/reports/playwright-html-report

Resolving issues

E2E test browsers not installed

Run npx playwright install to download test browsers and resolve the error below when running yarn test-e2e:

Executable doesn't exist at /Users/alice/Library/Caches/ms-playwright/chromium-1048/chrome-mac/Chromium.app/Contents/MacOS/Chromium

Upgrading from earlier versions

1. Pull the current version:

   git pull

2. Check if dependencies got added/updated/removed

   yarn

3. Apply database migrations by running one of the following commands:

   In a development environment, run:

   yarn workspace @calcom/prisma db-migrate

   (This can clear your development database in some cases)

   In a production environment, run:

   yarn workspace @calcom/prisma db-deploy

4. Check for .env variables changes

   yarn predev

5. Start the server. In a development environment, just do:

   yarn dev

   For a production build, run for example:

   yarn build
   yarn start

6. Enjoy the new version.

Deployment

Docker

The Docker image can be found on DockerHub at https://hub.docker.com/r/calcom/cal.diy.

Note for ARM Users: Use the {version}-arm suffix for pulling images. Example: docker pull calcom/cal.diy:v5.6.19-arm.

Requirements

Make sure you have docker & docker compose installed on the server / system. Both are installed by most docker utilities, including Docker Desktop and Rancher Desktop.

Note: docker compose without the hyphen is now the primary method of using docker-compose, per the Docker documentation.

Running Cal.diy with Docker Compose

1. Clone the repository

   git clone --recursive https://github.com/calcom/cal.diy.git

2. Change into the directory

   cd cal.diy

3. Prepare your configuration: Rename .env.example to .env and then update .env

   cp .env.example .env

   Most configurations can be left as-is, but for configuration options see Important Run-time variables below.

   Required Secret Keys

   Before starting, you must generate secure values for NEXTAUTH_SECRET and CALENDSO_ENCRYPTION_KEY. Using the default secret placeholder in production is a security risk.

   Generate NEXTAUTH_SECRET (cookie encryption key):

   openssl rand -base64 32

   Generate CALENDSO_ENCRYPTION_KEY (must be 32 bytes for AES256):

   openssl rand -base64 24

   Update your .env file with these values:

   NEXTAUTH_SECRET=<your_generated_secret>
   CALENDSO_ENCRYPTION_KEY=<your_generated_key>

   Push Notifications (VAPID Keys) If you see an error like:

   Error: No key set vapidDetails.publicKey
   

   This means your environment variables for Web Push are missing. You must generate and set NEXT_PUBLIC_VAPID_PUBLIC_KEY and VAPID_PRIVATE_KEY.

   Generate them with:

   npx web-push generate-vapid-keys

   Then update your .env file:

   NEXT_PUBLIC_VAPID_PUBLIC_KEY=your_public_key_here
   VAPID_PRIVATE_KEY=your_private_key_here

   Do not commit real keys to .env.example — only placeholders.

   Update the appropriate values in your .env file, then proceed.

4. (optional) Pre-Pull the images by running the following command:

   docker compose pull

5. Start Cal.diy via docker compose

   To run the complete stack, which includes a local Postgres database, Cal.diy web app, and Prisma Studio:

   docker compose up -d

   To run Cal.diy web app and Prisma Studio against a remote database, ensure that DATABASE_URL is configured for an available database and run:

   docker compose up -d calcom studio

   To run only the Cal.diy web app, ensure that DATABASE_URL is configured for an available database and run:

   docker compose up -d calcom

   Note: to run in attached mode for debugging, remove -d from your desired run command.

6. Open a browser to http://localhost:3000, or your defined NEXT_PUBLIC_WEBAPP_URL. The first time you run Cal.diy, a setup wizard will initialize. Define your first user, and you're ready to go!

   Note for first-time setup (Calendar integration): During the setup wizard, you may encounter a "Connect your Calendar" step that appears to be required. If you do not wish to connect a calendar at this time, you can skip this step by navigating directly to the dashboard at <NEXT_PUBLIC_WEBAPP_URL>/event-types. Calendar integrations can be added later from the Settings > Integrations page.

Updating Cal.diy

1. Stop the Cal.diy stack

   docker compose down

2. Pull the latest changes

   docker compose pull

3. Update env vars as necessary.

4. Re-start the Cal.diy stack

   docker compose up -d

Building from source with Docker

1. Clone the repository

   git clone https://github.com/calcom/cal.diy.git

2. Change into the directory

   cd cal.diy

3. Rename .env.example to .env and then update .env

   For configuration options see Build-time variables below. Update the appropriate values in your .env file, then proceed.

4. Build the Cal.diy docker image:

   Note: Due to application configuration requirements, an available database is currently required during the build process.

   a) If hosting elsewhere, configure the DATABASE_URL in the .env file, and skip the next step

   b) If a local or temporary database is required, start a local database via docker compose.

   docker compose up -d database

5. Build Cal.diy via docker compose (DOCKER_BUILDKIT=0 must be provided to allow a network bridge to be used at build time. This requirement will be removed in the future)

   DOCKER_BUILDKIT=0 docker compose build calcom

6. Start Cal.diy via docker compose

   To run the complete stack, which includes a local Postgres database, Cal.diy web app, and Prisma Studio:

   docker compose up -d

   To run Cal.diy web app and Prisma Studio against a remote database, ensure that DATABASE_URL is configured for an available database and run:

   docker compose up -d calcom studio

   To run only the Cal.diy web app, ensure that DATABASE_URL is configured for an available database and run:

   docker compose up -d calcom

   Note: to run in attached mode for debugging, remove -d from your desired run command.

7. Open a browser to http://localhost:3000, or your defined NEXT_PUBLIC_WEBAPP_URL. The first time you run Cal.diy, a setup wizard will initialize. Define your first user, and you're ready to go!

Configuration

Important Run-time variables

These variables must also be provided at runtime

Variable	Description	Required	Default
DATABASE_URL	database url with credentials - if using a connection pooler, this setting should point there	required	postgresql://unicorn_user:magical_password@database:5432/calendso
NEXT_PUBLIC_WEBAPP_URL	Base URL of the site. NOTE: if this value differs from the value used at build-time, there will be a slight delay during container start (to update the statically built files).	optional	http://localhost:3000
NEXTAUTH_URL	Location of the auth server. By default, this is the Cal.diy docker instance itself.	optional	{NEXT_PUBLIC_WEBAPP_URL}/api/auth
NEXTAUTH_SECRET	Cookie encryption key. Must match build variable. Generate with: openssl rand -base64 32	required	secret
CALENDSO_ENCRYPTION_KEY	Authentication encryption key (32 bytes for AES256). Must match build variable. Generate with: openssl rand -base64 24	required	secret

Build-time variables

If building the image yourself, these variables must be provided at the time of the docker build, and can be provided by updating the .env file. Currently, if you require changes to these variables, you must follow the instructions to build and publish your own image.

Variable	Description	Required	Default
DATABASE_URL	database url with credentials - if using a connection pooler, this setting should point there	required	postgresql://unicorn_user:magical_password@database:5432/calendso
MAX_OLD_SPACE_SIZE	Needed for Nodejs/NPM build options	required	4096
NEXTAUTH_SECRET	Cookie encryption key	required	secret
CALENDSO_ENCRYPTION_KEY	Authentication encryption key	required	secret
NEXT_PUBLIC_WEBAPP_URL	Base URL injected into static files	optional	http://localhost:3000
NEXT_PUBLIC_WEBSITE_TERMS_URL	custom URL for terms and conditions website	optional
NEXT_PUBLIC_WEBSITE_PRIVACY_POLICY_URL	custom URL for privacy policy website	optional
CALCOM_TELEMETRY_DISABLED	Allow Cal.diy to collect anonymous usage data (set to 1 to disable)	optional

Troubleshooting

SSL edge termination

If running behind a load balancer which handles SSL certificates, you will need to add the environmental variable NODE_TLS_REJECT_UNAUTHORIZED=0 to prevent requests from being rejected. Only do this if you know what you are doing and trust the services/load-balancers directing traffic to your service.

Failed to commit changes: Invalid 'prisma.user.create()'

Certain versions may have trouble creating a user if the field metadata is empty. Using an empty json object {} as the field value should resolve this issue. Also, the id field will autoincrement, so you may also try leaving the value of id as empty.

CLIENT_FETCH_ERROR

If you experience this error, it may be the way the default Auth callback in the server is using the WEBAPP_URL as a base url. The container does not necessarily have access to the same DNS as your local machine, and therefore needs to be configured to resolve to itself. You may be able to correct this by configuring NEXTAUTH_URL=http://localhost:3000/api/auth, to help the backend loop back to itself.

License

Cal.diy is fully open source, licensed under the MIT License.

Unlike Cal.com's "Open Core" model, Cal.diy has no commercial/enterprise code. The entire codebase is available under the same open-source license.

Enabling Content Security Policy

• Set CSP_POLICY="non-strict" env variable, which enables Strict CSP except for unsafe-inline in style-src . If you have some custom changes in your instance, you might have to make some code change to make your instance CSP compatible. Right now it enables strict CSP only on login page and on other SSR pages it is enabled in Report only mode to detect possible issues. On, SSG pages it is still not supported.
