What Zaryn can do

**Zaryn** ([zaryn.xyz](https://zaryn.xyz)) is a website for keeping your work online, sharing it and working on it with other people. **zev** is the program on your computer that saves versions of your project and sends them to Zaryn. You can do a lot from the website alone; zev is there when you want more. Each section below is one thing Zaryn does: what it's for, where it is on the site, and where to read more. ## Keep a project online, with every version A **repository** is a folder for one project (code, a thesis, a dataset, a website) that remembers every version you save. You can see what changed and go back to any earlier version. - **Where:** [Repos](/repos) in the top menu, then **New repository**. - **From the website:** open the repository and press **Upload** to add a file. Nothing to install. - **From your computer:** install zev and push a whole folder at once. [Quick start](/docs/en/quickstart) walks you through it in about five minutes. - **Free:** unlimited public repositories, 5 private ones, 2 GB in total, files up to 250 MB. > **Public or private?** Anyone can see a public repository. A private one only you and the people you invite can see, and it can also be [encrypted](/docs/en/encrypted-repositories) so not even Zaryn can read it. ## Share a file with a link Upload a file, get a link, send it to anyone. They don't need an account. - **Where:** [Storage](/storage) in the top menu. - **Free:** 500 MB, up to 50 files. - **Guide:** [Storing and sharing files](/docs/en/storing-files). These files are public, so read the warning there before you upload. The same page shows how much space your repositories, files and packages use. ## Work with other people - **Invite someone** to a repository: open it, then **Collaborators**. - **Report a problem or suggest an idea** with an **issue** (the **Issues** tab on a repository). - **Propose a change** and ask for a review with a **pull request**: the owner reads it, comments and merges it when it's ready. - **Work as a team** under one name with an **organization**: [Repos](/repos), then **New organization**. - **Talk privately:** [Messages](/messages). **Guides:** [How do I…?](/docs/en/how-do-i) (the "Share and work together" part) and [Collaboration from the Terminal](/docs/en/cli-collaboration). ## Publish a package If you write a library, Zaryn hosts it for the tools you already use: npm, PyPI, Cargo, Zig, container images, or any file. - **Where:** [Packages](/packages). The page shows the exact command for each tool. - **Free:** 500 MB. - **Zig:** Zaryn reads your `build.zig.zon` and gives you the exact hash `zig fetch` will compute; any repository commit works as a dependency too. - **crates.io or GitHub slow?** cargo and zig can download through Zaryn's [mirrors](/docs/en/package-mirrors), checked against the hashes they already know. **Guides:** [Packages, explained](/docs/en/packages), then the one for your tool. ## Test your project on every push (CI) CI builds and tests your project automatically each time you send new work, so you hear about a broken change right away. ```bash zev ci enable zev ci status ``` - **Free:** 400 minutes a month. - **Guides:** [zev ci](/docs/en/commands#zev-ci); how it skips work it has already done is in [Memoized CI](/docs/en/memoized-ci). ## Know when something you use is unsafe Zaryn tracks security problems (**advisories**) in libraries and tells you when one reaches your project. A repository's **Security scan** tab checks it on demand. - **Where:** [Advisories](/advisories), and the **Security scan** tab on each repository. - **Free:** yes. Only the live graph of who's affected is Premium. - **Guide:** [Advisories and lineage](/docs/en/advisories). ## Reach Zaryn when the internet is filtered `zev proxy` sends zev's traffic through a proxy server you already have (VLESS, VMess, Trojan, Shadowsocks, Hysteria2 and more), and `zev proxy doctor` finds out what's being blocked and how to get around it. - **Free:** on every plan. Zaryn carries none of this traffic. - **Guide:** [Using zev through a proxy](/docs/en/proxy). ## Connect your devices privately (Premium) A **private network** joins your laptop, servers and teammates' machines so they can reach each other directly and encrypted, wherever they are. - **Where:** [Network](/network). - **Guide:** [Private networks](/docs/en/private-networks). ## Let an app, CI or AI agent use Zaryn A **project** holds API keys for a program that calls Zaryn: each key has its own permissions, limits and usage numbers. Hosted AI models are part of Premium. - **Where:** [Projects](/projects). - **Free:** 50,000 API requests a month, up to 60 a minute. - **Guide:** [Scripting and AI Agents](/docs/en/automation-and-agents). ## Plans and paying Everything above has a Free plan; **Premium** raises the limits and adds private networks, hosted AI and more. You top up Zaryn credits with USDC, and credits pay for Premium. - **Where:** [Billing](/billing), which also shows what you've used. - **Guide:** [Billing and Zaryn credits](/docs/en/billing-and-credits). ## Still not sure where to go? - Press `/` on any docs page and type what you want to do, in your own words: "share a file", "undo", "invite someone". - [How do I…?](/docs/en/how-do-i) has short answers to the most common tasks. - [When something goes wrong](/docs/en/troubleshooting) explains error messages. - Still stuck?
