This page compares architecture and feature breadth, not maturity. Levelrail is pre-release and most feature areas are labelled beta.
It is positioning, not a ranking: any of these may be the right choice for you.
Only what each project's own documentation states. A question mark means their docs do not say, not that the answer is no. Point at a cell for its note and source, or switch on Notes. A question mark is a gap in their docs, listed once per row.
As of 2026-10. Statements about other projects come from their own public documentation, linked on each cell, and can be out of date. Product names and logos belong to their owners and are used for identification only.
Where Levelrail is behind or still unproven.
Built from our own cells that are not a plain yes. Each links to the page that states the limit.
Docker Compose apps
Pre-built images from the dashboard; git deploys can build
OAuth and OIDC are supported. SAML and SCIM sit behind a beta flag and are not tested against a live provider.
02
The largest template catalog
Levelrail ships 358 templates, but other projects may list more, and only a sample of ours is live-deployed in the end-to-end suite.
03
Track record
Fewer real-world deployments and less community knowledge than projects that have existed for years.
04
Public ACME has had one live run
TLS defaults to an internal issuer. The public issuer was verified once against Let’s Encrypt. Renewal and DNS-01 wildcards are not yet exercised live.
05
Windows and Kubernetes
No Windows or non-Linux nodes and no Kubernetes compatibility layer. These are deliberate non-goals.
The full list of limits, with status badges, lives on the open source page.

Built from the sourced matrix above, so the answers stay as honest as the table.
What is the best self-hosted alternative to Coolify?
It depends on what you want. Dokploy and CapRover fit a Docker Swarm model, Dokku and Kamal fit one server with the fewest moving parts, and Levelrail fits teams that want an agent-based control plane with metrics, logs, IAM and audit in one binary. Levelrail is pre-release and Coolify has the larger template catalog and track record, so read the sourced comparison before choosing.
What is a self-hosted alternative to Vercel, Heroku or Railway?
Levelrail gives you git push deploys, preview environments, TLS, logs, metrics and rollback on servers you own. It does not offer a global edge network, serverless functions or a managed cloud, so if you need those, a hosted platform is the better fit. Dokku is the closest minimal option for a single server.
Can I migrate from Coolify, Dokploy or CapRover to Levelrail?
Yes. Levelrail has a read-only importer with a dry-run mode, so you can keep the old platform running while you try the new one, then move DNS when you trust it. The migration guide in the docs walks through it.
Which self-hosted deployment platform is the lightest?
Levelrail is one Go binary for the control plane and one for the agent. On a development build it idled at 68 MB of memory with no apps and 91 MB with 500 suspended apps. Those are pre-release numbers from one machine, and the method and limits are published in the docs.
Is Levelrail a good alternative to Coolify?
Large catalog of one-click services and a polished dashboard, managing existing servers over plain SSH. How Levelrail differs: An agent dials out over mTLS to the Docker Engine API instead of SSH from the control plane. A level-triggered reconciler records a status reason per pass, instead of Docker Compose per resource. Metrics, log search and rollback with pinned images ship in the core. Choose Coolify instead when you want the broadest template list and SSH-only server management. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Dokploy?
A polished project built on Docker Swarm, with a modern dashboard on top. How Levelrail differs: Plain Docker with a reconciler and a small agent per node, with no Swarm or overlay network. Metrics, full-text logs and crashloop detection ship in the core with no extra stack. One Go binary with embedded SQLite and embedded Caddy, instead of Traefik. Choose Dokploy instead when docker Swarm is already your model, and you want multi-node scheduling and rolling updates from a mature mechanism. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to CapRover?
A long-running, simple, Swarm-based platform with a one-click app store and a CLI. How Levelrail differs: Plain Docker containers with a level-triggered reconciler instead of Swarm services. An agent per node dials out over mTLS, so managed servers need no inbound port. Caddy embedded for ingress instead of nginx, with metrics and logs in the core. Choose CapRover instead when docker Swarm is already your model, or you want a long-running platform with a large install base and app store. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Dokku?
The classic Heroku on your own box: git push to deploy, buildpacks, a rich plugin ecosystem. How Levelrail differs: A dashboard with deploy history and one-click rollback to a pinned previous image. Metrics and log search in the core, where Dokku suggests adding your own stack. More servers join with a one-time token and an agent that dials out. Choose Dokku instead when you run one server and want the simplest possible thing. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Kamal?
Deliberately minimal: no control plane, database or agent, running over SSH from your machine or CI. How Levelrail differs: Desired state lives in a database, with a reconciler recording a status reason after every pass. Agents dial out, so CI uses a scoped API token instead of holding SSH keys. Adds a dashboard, deploy history, rollback and built-in observability, and is heavier by design. Choose Kamal instead when you want the fewest possible moving parts and do not need a dashboard. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Vercel?
A managed cloud with a global edge network, git integration, previews and instant rollback. How Levelrail differs: Runs on Linux servers you own, so secrets, metrics and logs stay on your nodes. Cost is the servers you rent, not per request or per seat. Long-lived containers built from a Dockerfile, with no serverless functions or edge network. Choose Vercel instead when you need a global edge network or serverless functions; Levelrail offers neither and suggests a CDN in front. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Heroku?
A managed platform: git push, buildpacks and release phase, billed per dyno and per add-on. How Levelrail differs: Runs on Linux boxes you own, with no per-dyno or per-app fee. Eight managed database engines with scheduled, verified backups instead of add-ons. Dockerfile builds with readiness-gated cutover, not buildpacks. Choose Heroku instead when you want the vendor to handle operations, since with Levelrail you are the one on call for the servers. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Railway?
A vendor-managed cloud with usage-based pricing and environments per pull request. How Levelrail differs: Runs on your Linux servers, so pricing is your own server cost. Secrets, metrics and logs stay on your nodes unless you configure an export. Self-hosted software only; there is no managed cloud version. Choose Railway instead when you want a vendor-managed cloud rather than operating your own servers; Levelrail has no managed version. Levelrail is pre-release, so check the comparison for what it does not do yet.
Is Levelrail a good alternative to Cloud Run?
A good fit for bursty traffic, with scale to zero and per-request billing. How Levelrail differs: A fixed-price server you run, so cost does not move with traffic. Replicas are fixed with no autoscaling, and wake from sleep is slower than a cold start. Logs, metrics and data stay on machines you control, with nothing billed by volume. Choose Cloud Run instead when traffic is spiky or rare, you need capacity in seconds, or you depend on Google identity and networking features. Levelrail is pre-release, so check the comparison for what it does not do yet.
