# Grist
2021-05-15 16:12:36 +00:00
Grist is a modern relational spreadsheet. It combines the flexibility of a spreadsheet with the
robustness of a database to organize your data and make you more productive.

## Features
(By popular request: we have a specific write-up of [Grist vs Airtable](https://www.getgrist.com/blog/grist-v-airtable/) that may be helpful).
Grist is a hybrid database/spreadsheet, meaning that:
- Columns work like they do in databases. They are named, and hold one kind of data.
- Columns can be filled by formula, spreadsheet-style, with automatic updates when referenced cells change.
Here are some specific feature highlights of Grist:
* Python formulas.
- Full [Python syntax is supported](https://support.getgrist.com/formulas/#python), and the standard library.
- Many [Excel functions](https://support.getgrist.com/functions/) also available.
* A portable, self-contained format.
- Based on SQLite, the most widely deployed database engine.
- Any tool that can read SQLite can read numeric and text data from a Grist file.
- Great format for [backups](https://support.getgrist.com/exports/#backing-up-an-entire-document) that you can be confident you can restore in full.
- Great format for moving between different hosts.
* Convenient editing and formatting features.
- Choices and [choice lists](https://support.getgrist.com/col-types/#choice-list-columns), for adding colorful tags to records without fuss.
- [References](https://support.getgrist.com/col-refs/#creating-a-new-reference-list-column) and reference lists, for cross-referencing records in other tables.
- [Attachments](https://support.getgrist.com/col-types/#attachment-columns), to include media or document files in records.
- Dates and times, toggles, and special numerics such as currency all have specialized editors and formatting options.
* Great for dashboards, visualizations, and data entry.
- [Charts](https://support.getgrist.com/widget-chart/) for visualization.
- [Summary tables](https://support.getgrist.com/summary-tables/) for summing and counting across groups.
- [Widget linking](https://support.getgrist.com/linking-widgets/) streamlines filtering and editing data.
Grist has a unique approach to visualization, where you can lay out and link distinct widgets to show together,
without cramming mixed material into a table.
- The [Filter bar](https://support.getgrist.com/search-sort-filter/#filter-buttons) is great for quick slicing and dicing.
* [Incremental imports](https://support.getgrist.com/imports/#updating-existing-records).
- So you can import a CSV of the last three months activity from your bank...
- ... and import new activity a month later without fuss or duplicates.
* Integrations.
- A [REST API](https://support.getgrist.com/api/), [Zapier actions/triggers](https://support.getgrist.com/integrators/#integrations-via-zapier), and support from similar [integrators](https://support.getgrist.com/integrators/).
- Import/export to Google drive, Excel format, CSV.
- Can link data with custom widgets hosted externally.
* [Many templates](https://templates.getgrist.com/) to get you started, from investment research to organizing treasure hunts.
* Access control options.
- (You'll need SSO logins set up to make use of these options)
- Share [individual documents](https://support.getgrist.com/sharing/), or workspaces, or [team sites](https://support.getgrist.com/team-sharing/).
- Control access to [individual rows, columns, and tables](https://support.getgrist.com/access-rules/).
- Control access based on cell values and user attributes.
* Can be self-maintained.
- Useful for intranet operation and specific compliance requirements.
* Sandboxing options for untrusted documents.
- On Linux or with docker, you can enable
[gVisor](https://github.com/google/gvisor) sandboxing at the individual
document level.
- On OSX, you can use native sandboxing.

## Using Grist
2020-10-29 21:54:45 +00:00
There are docker images set up for individual use, or (with some
configuration) for self-hosting. Grist Labs offers a hosted service
at [docs.getgrist.com](https://docs.getgrist.com).
To get Grist running on your computer with [Docker](https://www.docker.com/get-started), do:
```sh
docker pull gristlabs/grist
docker run -p 8484:8484 -it gristlabs/grist
```
Then visit `http://localhost:8484` in your browser. You'll be able to create, edit, import,
and export documents. To preserve your work across docker runs, share a directory as `/persist`:
```sh
docker run -p 8484:8484 -v $PWD/persist:/persist -it gristlabs/grist
```
Get templates at [templates.getgrist.com](https://templates.getgrist.com) for payroll,
inventory management, invoicing, D&D encounter tracking, and a lot
more, or use any document you've created on
[docs.getgrist.com](https://docs.getgrist.com).
2020-10-29 21:54:45 +00:00
If you need to change the port Grist runs on, set a `PORT` variable, don't just change the
port mapping:
2020-10-29 21:54:45 +00:00
```
docker run --env PORT=9999 -p 9999:9999 -v $PWD/persist:/persist -it gristlabs/grist
```
To enable gVisor sandboxing, set `--env GRIST_SANDBOX_FLAVOR=gvisor`.
This should work with default docker settings, but may not work in all
environments.
## Building from source
To build Grist from source, follow these steps:
2020-10-29 21:54:45 +00:00
yarn install
yarn run build:prod
yarn run install:python
yarn start
# Grist will be available at http://localhost:8484/
2020-10-29 21:54:45 +00:00
Grist formulas in documents will be run using Python executed directly on your
machine. You can configure sandboxing using a `GRIST_SANDBOX_FLAVOR`
environment variable.
* On OSX, `export GRIST_SANDBOX_FLAVOR=macSandboxExec`
uses the native `sandbox-exec` command for sandboxing.
* On Linux with [gVisor's runsc](https://github.com/google/gvisor)
installed, `export GRIST_SANDBOX_FLAVOR=gvisor` is an option.
These sandboxing methods have been written for our own use at Grist Labs and
may need tweaking to work in your own environment - pull requests
very welcome here!
## Logins
Like git, Grist has features to track document revision history. So for full operation,
Grist expects to know who the user modifying a document is. Until it does, it operates
in a limited anonymous mode. To get you going, the docker image is configured so that
when you click on the "sign in" button Grist will attribute your work to `you@example.com`.
Change this by setting `GRIST_DEFAULT_EMAIL`:
```
docker run --env GRIST_DEFAULT_EMAIL=my@email -p 8484:8484 -v $PWD/persist:/persist -it gristlabs/grist
```
You can change your name in `Profile Settings` in
the [User Menu](https://support.getgrist.com/glossary/#user-menu).
For multi-user operation, and/or if you wish to access Grist across the
public internet, you'll want to connect it to your own single sign-in service
[SAML](https://github.com/gristlabs/grist-core/blob/main/app/server/lib/SamlConfig.ts).
Grist has been tested with [Authentik](https://goauthentik.io/) and [Auth0](https://auth0.com/).
## Why free and open source software
2020-10-29 21:54:45 +00:00
This repository, [grist-core](https://github.com/gristlabs/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 it 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 intend to 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 Grist can bring to our
users, and `grist-core` as an essential means to deliver 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.
By opening its source code and offering an [OSI](https://opensource.org/)-approved free license,
Grist benefits its users:
- **Developer community.** The freedom to examine source code, make bug fixes, and develop
new features is a big deal for a general-purpose spreadsheet-like product, where there is a
very long tail of features vital to someone somewhere.
- **Increased trust.** Because anyone can examine the source code, “security by obscurity” is not
an option. Vulnerabilities in the code can be found by others and reported before they cause
damage.
- **Independence.** Grist is available to you regardless of the fortunes of the Grist Labs business,
since it is open source and can be self-hosted. Using our hosted solution is convenient, but you
are not locked in.
- **Price flexibility.** If you are low on funds but have time to invest, self-hosting is a great
option to have. And DIY users may have the technical savvy and motivation to delve in and make improvements,
which can benefit all users of Grist.
- **Extensibility.** For developers, having the source open makes it easier to build extensions (such as the
experimental [Custom Widget](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.
