# Tenkai > Tenkai turns any server you own into a deployment platform, from a cloud VPS to the Raspberry Pi on your shelf. The guides of the Help Center explain how Tenkai works and how a team deploys and runs its applications with it. Each one is Markdown at its address with `.md` appended, and [llms-full.txt](https://tenkai.cloud/llms-full.txt) holds them all. A coding agent, such as Claude Code, Codex or Cursor, works in Tenkai through its MCP server at https://tenkai.cloud/mcp, and signs in with OAuth. The guide on [agent tokens](https://tenkai.cloud/help/agent-tokens.md) explains how to connect one. ## Get started - [What is Tenkai?](https://tenkai.cloud/help/what-is-tenkai.md): Understand where Tenkai runs your applications, how a server becomes a deployment platform and what you remain responsible for. - [Deploy your first application](https://tenkai.cloud/help/first-deployment.md): Deploy your first web application on Tenkai from a public container image, configure its runtime port and check the HTTPS route. - [Projects, environments and clusters](https://tenkai.cloud/help/projects-and-clusters.md): Understand how Tenkai groups resources, prepares clusters and creates the production environment for your project. - [Your team and its settings](https://tenkai.cloud/help/team-settings.md): See what a team owns, create a team and switch between your teams, rename it, change its icon, choose what a new cluster starts with, and read what each team role may do. - [Plans and billing](https://tenkai.cloud/help/billing.md): See how many servers each plan allows, subscribe, upgrade or switch to a lower plan, change the card, read the invoices and cancel the subscription. - [Your account](https://tenkai.cloud/help/account.md): Change your password, sign in with GitHub, choose the theme, and find the credentials that belong to you rather than to a team. - [Read your team's overview](https://tenkai.cloud/help/overview.md): Find what needs you across your team, from agent requests to failed deployments, and follow each cluster's load and each project's traffic. - [Compare Tenkai with Coolify and Dokploy](https://tenkai.cloud/help/compare-coolify-dokploy.md): See what Coolify and Dokploy leave to you in production, from the cluster to database failover, backups and your app versions. ## How Tenkai works - [How Tenkai runs your applications](https://tenkai.cloud/help/how-tenkai-works.md): See what Tenkai does from its control plane, what runs on your servers and how a deployment reaches them. - [Clusters and the roles of their nodes](https://tenkai.cloud/help/clusters.md): Understand the edge node, manager nodes, worker nodes and data nodes, how many failures a cluster survives, and how replicas spread across nodes. - [Run servers anywhere with the cluster network](https://tenkai.cloud/help/cluster-network.md): Mix Hetzner Cloud, DigitalOcean, Scaleway, Infomaniak Public Cloud and your own hardware in one cluster, linked by an encrypted WireGuard mesh. - [How traffic reaches your application](https://tenkai.cloud/help/edge-node.md): Follow a request from DNS to the edge node, through HTTPS and the edge router, to a replica on any node of the cluster. - [How a deployment switches traffic](https://tenkai.cloud/help/blue-green-deployments.md): See how a blue-green deployment starts a candidate next to the active release, checks it, then moves the routes to it. - [How a drain moves your applications](https://tenkai.cloud/help/drain.md): See how Tenkai moves each web application and each worker off a node before maintenance or removal, and what cannot move. ## Applications - [Choose an application source](https://tenkai.cloud/help/application-sources.md): Deploy from a Git repository with a Dockerfile, build from source, use a container image from Docker Hub or GHCR, or send a static site's files. -

[Preview each pull request](https://tenkai.cloud/help/pull-request-previews.md): Turn on pull request previews for a project, so each pull request gets its own environment, deployed on each push and deleted once it closes. - [Run a command before a deployment or a rollback](https://tenkai.cloud/help/deployment-commands.md): Give a web application pre-deploy commands for its database migrations and rollback commands to undo them, and know when each runs and what a failure does. -
