*`grist-core` (this repo) has what you need to run a powerful spreadsheet hosting server.
* [`grist-electron`](https://github.com/gristlabs/grist-electron) is a Linux/macOS/Windows desktop app for viewing and editing spreadsheets stored locally.
* [`grist-static`](https://github.com/gristlabs/grist-static) is a fully in-browser build of Grist for displaying spreadsheets on a website without back-end support.
The `grist-core` repo is the heart of Grist, including the hosted services offered by [Grist Labs](https://getgrist.com), an NYC-based company 🇺🇸 and Grist's main developer. The French government agency [ANCT Données et Territoires](https://donnees.incubateur.anct.gouv.fr/toolbox/grist) 🇫🇷 has also made significant contributions to the codebase.

This difference can confuse people coming directly from Excel or Google Sheets. Give it a chance! There's also a [Grist for Spreadsheet Users](https://www.getgrist.com/blog/grist-for-spreadsheet-users/) article to help get you oriented. If you're coming from Airtable, you'll find the model familiar (and there's also our [Grist vs Airtable](https://www.getgrist.com/blog/grist-v-airtable/) article for a direct comparison).

public internet, you'll want to connect it to your own Single Sign-On service.
There are a lot of ways to do this, including [SAML and forward authentication](https://support.getgrist.com/self-managed/#how-do-i-set-up-authentication).
Grist has been tested with [Authentik](https://goauthentik.io/), [Auth0](https://auth0.com/),
and Google/Microsoft sign-ins via [Dex](https://dexidp.io/).
This repository, `grist-core`, is maintained by Grist Labs. Our flagship product available at [getgrist.com](https://www.getgrist.com) is built from the code you see here, combined with business-specific software designed to scale to many users, handle billing, etc.
Grist Labs is an open-core company. We offer Grist hosting as a service, with free and paid plans. We also develop and sell features related to Grist using a proprietary license, targeted at the needs of enterprises with large self-managed installations.
We see data portability and autonomy as a key value, and `grist-core` is an essential part of that. We are committed to maintaining and improving the `grist-core` codebase, and to be thoughtful about how proprietary offerings impact data portability and autonomy.
- **Extensibility.** For developers, having the source open makes it easier to build extensions (such as [Custom Widgets](https://support.getgrist.com/widget-custom/)). You can more easily include Grist in your pipeline. And if a feature is missing, you can just take the source code and build on top of it.
For more on Grist Labs' history and principles, see our [About Us](https://www.getgrist.com/about/) page.
| ALLOWED_WEBHOOK_DOMAINS | comma-separated list of permitted domains to use in webhooks (e.g. webhook.site,zapier.com). You can set this to `*` to allow all domains, but if doing so, we recommend using a carefully locked-down proxy (see `GRIST_HTTPS_PROXY`) if you do not entirely trust users. Otherwise services on your internal network may become vulnerable to manipulation. |
| APP_DOC_URL | doc worker url, set when starting an individual doc worker (other servers will find doc worker urls via redis) |
| APP_DOC_INTERNAL_URL | like `APP_DOC_URL` but used by the home server to reach the server using an internal domain name resolution (like in a docker environment). You may only define this value in the doc worker. Defaults to `APP_DOC_URL`. |
| APP_HOME_INTERNAL_URL | like `APP_HOME_URL` but used by the home server to reach any home workers using an internal domain name resolution (like in a docker environment). Defaults to `APP_HOME_URL` |
| GRIST_DATA_DIR | Directory in which to store documents. Defaults to `docs/` relative to the Grist application directory. In Grist's default Docker image, its default value is /persist/docs so that it will be used as a mounted volume. |
| GRIST_ENABLE_REQUEST_FUNCTION | enables the REQUEST function. This function performs HTTP requests in a similar way to `requests.request`. This function presents a significant security risk, since it can let users call internal endpoints when Grist is available publicly. This function can also cause performance issues. Unset by default. |
| GRIST_HIDE_UI_ELEMENTS | comma-separated list of UI features to disable. Allowed names of parts: `helpCenter,billing,templates,createSite,multiSite,multiAccounts,sendToDrive,tutorials,supportGrist`. If a part also exists in GRIST_UI_FEATURES, it will still be disabled. |
| GRIST_HOST | hostname to use when listening on a port. |
| GRIST_HTTPS_PROXY | if set, use this proxy for webhook payload delivery. |
| GRIST_ID_PREFIX | for subdomains of form o-*, expect or produce o-${GRIST_ID_PREFIX}*. |
| GRIST_IGNORE_SESSION | if set, Grist will not use a session for authentication. |
| GRIST_INCLUDE_CUSTOM_SCRIPT_URL | if set, will load the referenced URL in a `<script>` tag on all app pages. |
| GRIST_INST_DIR | path to Grist instance configuration files, for Grist server. |
| GRIST_LIST_PUBLIC_SITES | if set to true, sites shared with the public will be listed for anonymous users. Defaults to false. |
| GRIST_MANAGED_WORKERS | if set, Grist can assume that if a url targeted at a doc worker returns a 404, that worker is gone |
| GRIST_MAX_UPLOAD_ATTACHMENT_MB | max allowed size for attachments (0 or empty for unlimited). |
| GRIST_MAX_UPLOAD_IMPORT_MB | max allowed size for imports (except .grist files) (0 or empty for unlimited). |
| GRIST_OFFER_ALL_LANGUAGES | if set, all translated langauages are offered to the user (by default, only languages with a special 'good enough' key set are offered to user). |
| GRIST_ORG_IN_PATH | if true, encode org in path rather than domain |
| GRIST_PAGE_TITLE_SUFFIX | a string to append to the end of the `<title>` in HTML documents. Defaults to `" - Grist"`. Set to `_blank` for no suffix at all. |
| ~GRIST_PROXY_AUTH_HEADER~ | Deprecated, and interpreted as a synonym for GRIST_FORWARD_AUTH_HEADER. |
| GRIST_ROUTER_URL | optional url for an api that allows servers to be (un)registered with a load balancer |
| GRIST_SERVE_SAME_ORIGIN | set to "true" to access home server and doc workers on the same protocol-host-port as the top-level page, same as for custom domains (careful, host header should be trustworthy) |
| GRIST_SERVERS | the types of server to setup. Comma separated values which may contain "home", "docs", static" and/or "app". Defaults to "home,docs,static". |
| GRIST_SESSION_COOKIE | if set, overrides the name of Grist's cookie |
| GRIST_SESSION_DOMAIN | if set, associates the cookie with the given domain - otherwise defaults to GRIST_DOMAIN |
| GRIST_SESSION_SECRET | a key used to encode sessions |
| GRIST_SKIP_BUNDLED_WIDGETS | if set, Grist will ignore any bundled widgets included via NPM packages. |
| GRIST_ANON_PLAYGROUND | When set to 'false' deny anonymous users access to the home page |
| GRIST_FORCE_LOGIN | Much like GRIST_ANON_PLAYGROUND but don't support anonymous access at all (features like sharing docs publicly requires authentication) |
| GRIST_SINGLE_ORG | set to an org "domain" to pin client to that org |
| GRIST_TEMPLATE_ORG | set to an org "domain" to show public docs from that org |
| GRIST_HELP_CENTER | set the help center link ref |
| FREE_COACHING_CALL_URL | set the link to the human help (example: email adress or meeting scheduling tool) |
| GRIST_CONTACT_SUPPORT_URL | set the link to contact support on error pages (example: email adress or online form) |
| GRIST_SUPPORT_ANON | if set to 'true', show UI for anonymous access (not shown by default) |
| GRIST_SUPPORT_EMAIL | if set, give a user with the specified email support powers. The main extra power is the ability to share sites, workspaces, and docs with all users in a listed way. |

| GRIST_THROTTLE_CPU | if set, CPU throttling is enabled |
| GRIST_TRUST_PLUGINS | if set, plugins are expect to be served from the same host as the rest of the Grist app, rather than from a distinct host. Ordinarily, plugins are served from a distinct host so that the cookies used by the Grist app are not automatically available to them. Enable this only if you understand the security implications. |
| GRIST_USER_ROOT | an extra path to look for plugins in - Grist will scan for plugins in `$GRIST_USER_ROOT/plugins`. |
| GRIST_UI_FEATURES | comma-separated list of UI features to enable. Allowed names of parts: `helpCenter,billing,templates,createSite,multiSite,multiAccounts,sendToDrive,tutorials,supportGrist`. If a part also exists in GRIST_HIDE_UI_ELEMENTS, it won't be enabled. |
| GRIST_UNTRUSTED_PORT | if set, plugins will be served from the given port. This is an alternative to setting APP_UNTRUSTED_URL. |
| GRIST_WIDGET_LIST_URL | a url pointing to a widget manifest, by default `https://github.com/gristlabs/grist-widget/releases/download/latest/manifest.json` is used |
| COOKIE_MAX_AGE | session cookie max age, defaults to 90 days; can be set to "none" to make it a session cookie |
| HOME_PORT | port number to listen on for REST API server; if set to "share", add API endpoints to regular grist port. |
| PORT | port number to listen on for Grist server |
| REDIS_URL | optional redis server for browser sessions and db query caching |
| GRIST_SKIP_REDIS_CHECKSUM_MISMATCH | Experimental. If set, only warn if the checksum in Redis differs with the one in your S3 backend storage. You may turn it on if your backend storage implements the [read-after-write consistency](https://aws.amazon.com/fr/blogs/aws/amazon-s3-update-strong-read-after-write-consistency/). Defaults to false. |
| GRIST_SNAPSHOT_KEEP | optional. Number of recent snapshots to retain unconditionally for a document, regardless of when they were made |
| GRIST_PROMCLIENT_PORT | optional. If set, serve the Prometheus metrics on the specified port number. ⚠️ Be sure to use a port which is not publicly exposed ⚠️. |
ASSISTANT_API_KEY | optional. An API key to pass when making requests to an external AI conversational endpoint.
ASSISTANT_CHAT_COMPLETION_ENDPOINT | optional. A chat-completion style endpoint to call. Not needed if OpenAI is being used.
ASSISTANT_MODEL | optional. If set, this string is passed along in calls to the AI conversational endpoint.
ASSISTANT_LONGER_CONTEXT_MODEL | optional. If set, requests that fail because of a context length limitation will be retried with this model set.
OPENAI_API_KEY | optional. Synonym for ASSISTANT_API_KEY that assumes an OpenAI endpoint is being used. Sign up for an account on OpenAI and then generate a secret key [here](https://platform.openai.com/account/api-keys).
At the time of writing, the AI Assistant is known to function against OpenAI chat completion endpoints for gpt-3.5-turbo and gpt-4.
It can also function against the chat completion endpoint provided by <ahref="https://github.com/abetlen/llama-cpp-python">llama-cpp-python</a>.
GRIST_SANDBOX | a program or image name to run as the sandbox. See NSandbox.ts for nerdy details.
PYTHON_VERSION | can be 2 or 3. If set, documents without an engine setting are assumed to use the specified version of python. Not all sandboxes support all versions.
PYTHON_VERSION_ON_CREATION | can be 2 or 3. If set, newly created documents have an engine setting set to python2 or python3. Not all sandboxes support all versions.
GRIST_FORWARD_AUTH_HEADER | if set, trust the specified header (e.g. "x-forwarded-user") to contain authorized user emails, and enable "forward auth" logins.
GRIST_FORWARD_AUTH_LOGIN_PATH | if GRIST_FORWARD_AUTH_HEADER is set, Grist will listen at this path for logins. Defaults to `/auth/login`.
GRIST_FORWARD_AUTH_LOGOUT_PATH | if GRIST_FORWARD_AUTH_HEADER is set, Grist will forward to this path when user logs out.
