# The SnoutData stack The stack is what a project IS: a Postgres database and the servers in front of it, behind one HTTPS door. A hosted project on SnoutData Cloud runs it, and so does a folder on your own machine with Docker. Same servers, same paths, same two keys, same client code; only the URL changes. Every part is open source. ## What is in it - [Postgres 18](https://docs.snoutdata.com/stack/postgres): Upstream Postgres 18 with pgvector, pg_cron, pg_net, pg_graphql and SnoutTime built in. Your migrations, your extensions. - [The project API](https://docs.snoutdata.com/stack/api): One door, six paths, two keys. Row-level security decides what every request can see. - [Data API](https://docs.snoutdata.com/stack/data-api): REST and GraphQL generated from your schema, with nothing to deploy. - [Auth](https://docs.snoutdata.com/stack/auth): Sign-up, sign-in, sessions, multi-factor, OAuth and SAML single sign-on, with the users in your own database. - [Storage](https://docs.snoutdata.com/stack/storage): Files in buckets, governed by the same kind of policies as your rows, with image resizing. - [Realtime](https://docs.snoutdata.com/stack/realtime): Broadcast, presence and table changes over WebSockets. - [Functions](https://docs.snoutdata.com/stack/functions): Your own TypeScript next to the database, with its secrets. - [Push](https://docs.snoutdata.com/stack/push): Notifications to iPhone, Android and the web, from one API and from SQL. - [SnoutTime](https://docs.snoutdata.com/stack/snouttime/overview): Time series in plain Postgres: series tables, sealed columnar partitions, rollups. ## Where it runs | | Hosted (SnoutData Cloud) | Your own Docker | |---|---|---| | Postgres 18, extensions, SnoutTime | yes | yes | | Data API, auth, storage, realtime, functions, push | yes | yes | | Backups every few seconds, point-in-time restore | yes ([durability](https://docs.snoutdata.com/cloud/durability)) | your own (`pg_dump`, volume backups) | | Sleeps when idle, wakes on connect | yes | no | | Plans, the dashboard, status page | yes | no | - **[Run it yourself](https://docs.snoutdata.com/stack/self-hosting)**: the whole stack with Docker Compose, from [snoutdata/snout-stack](https://github.com/snoutdata/snout-stack). - **[Local development](https://docs.snoutdata.com/stack/local)**: just the database, on your machine, in one command. - **[Use the CLI with a local stack](https://docs.snoutdata.com/stack/cli-local-stack)**: migrations, types and functions against the stack on this machine. - **[Create a hosted project](https://docs.snoutdata.com/cloud/getting-started)**: the same stack, run for you. Moving between the two is a database dump and the files, since the schemas are the same ([move a database](https://docs.snoutdata.com/cloud/move-database)). ## The source | Part | Repository | |---|---| | The stack (compose file, gateway, setup) | [snoutdata/snout-stack](https://github.com/snoutdata/snout-stack) | | Auth | [snoutdata/snout-auth](https://github.com/snoutdata/snout-auth) | | Storage | [snoutdata/snout-storage](https://github.com/snoutdata/snout-storage) | | Image resizing | [snoutdata/snout-images](https://github.com/snoutdata/snout-images) | | Realtime | [snoutdata/snout-realtime](https://github.com/snoutdata/snout-realtime) | | Functions | [snoutdata/snout-functions](https://github.com/snoutdata/snout-functions) | | Push | [snoutdata/snout-push](https://github.com/snoutdata/snout-push) | | SnoutTime | [snoutdata/snouttime](https://github.com/snoutdata/snouttime) | | JavaScript client | [snoutdata/snout-client](https://github.com/snoutdata/snout-client) (`@snoutdata/client` on npm) | What changed, part by part, is in the [changelog](https://docs.snoutdata.com/cloud/changelog).
