+# Self hosting
+
+:::note
+The easiest way to get started with Typebot is with [our official managed service in the Cloud](https://app.typebot.io). It takes 1 minute to create your free account. You'll have high availability, backups, security, and maintenance all managed for you by Typebot. The section below is for self-hosting Typebot on your server and managing your infrastructure.
+:::
+
+Typebot is composed of 2 Next.js applications you need to deploy:
+
+- the builder, where you build your typebots
+- the viewer, where your user answer the typebot
+
+They are connected to a Database and an S3 bucket
+
+## S3
+
+Paste this bucket policy after replacing `<BUCKET_NAME>` with your bucket name:
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Sid": "PublicRead",
+      "Effect": "Allow",
+      "Principal": "*",
+      "Action": "s3:GetObject",
+      "Resource": "arn:aws:s3:::<BUCKET_NAME>/public/*"
+    }
+  ]
+}
+```
+
+CORS config:
+
+```json
+[
+  {
+    "AllowedHeaders": ["*"],
+    "AllowedMethods": ["PUT", "POST"],
+    "AllowedOrigins": ["*"],
+    "ExposeHeaders": ["ETag"]
+  }
+]
+```
+
+```
+S3_ACCESS_KEY=minio
+S3_SECRET_KEY=minio123
+S3_BUCKET=typebot
+S3_PORT=9000
+S3_ENDPOINT=localhost
+S3_SSL=false
+```
