WebSocket apps need persistent processes — many hosting platforms kill long-lived connections. Here are five options that don't, from PaaS simplicity to managed Kubernetes to decentralized compute, with honest tradeoffs for each.
WebSocket connections are long-lived TCP connections that stay open between client and server. That's the whole point — persistent bidirectional communication for chat apps, live dashboards, multiplayer games, and collaboration tools. But many popular hosting platforms, especially serverless and edge function providers, impose connection timeouts or don't support persistent processes at all. Your WebSocket server gets killed mid-conversation.
The platforms in this guide all run persistent processes or full containers — no connection timeouts, no cold-start surprises. They differ in how much ops overhead you take on, how they scale, and how transparent the pricing is.
Railway is a PaaS that runs full application processes (not serverless functions), which means WebSocket connections work natively with no special configuration.1 You get managed Postgres for persisting real-time state, instant deploys from GitHub, and a developer experience that gets you from git push to live WebSocket server in minutes.
For most teams building chat apps, live dashboards, or collaboration tools, Railway hits the sweet spot: enough control to run a real process, not enough complexity to need a Kubernetes certification.
Render offers a unified platform with web services that support WebSocket connections out of the box.2 Auto-deploy from GitHub, free SSL, and managed PostgreSQL make it a strong prototyping environment. The free tier is the headline feature — you can stand up a real-time app and test it without spending anything, then scale up when you're ready.
The tradeoff: free-tier resources are limited, and you'll hit scaling ceilings faster than on a managed K8s cluster. But for getting a real-time prototype in front of users, Render is hard to beat.
VKE gives you managed Kubernetes with competitive node pricing and global availability.3 Full container control means zero WebSocket limitations — you configure ingress, connection limits, and scaling exactly how you want. Pair it with Argo CD for GitOps-based deployment pipelines and you get a production-grade real-time infrastructure stack.6
The catch: you're managing Kubernetes. There's more ops overhead than a PaaS, and you need to understand ingress controllers, pod autoscaling, and resource limits. For teams already comfortable with K8s, VKE's pricing is hard to argue with.
LKE offers a free control plane, high-performance SSDs, and simple scaling.4 Like VKE, full container support means no WebSocket restrictions. The pricing model is transparent and flat-rate — you know what you're paying per node, and the control plane doesn't add to the bill.
LKE and VKE serve the same audience (teams who want K8s control), but LKE edges ahead on raw performance with its SSD infrastructure and straightforward pricing. The choice between them often comes down to which provider's region map better fits your users.
Aleph Cloud takes a fundamentally different approach: VM-based compute on a distributed network with no single point of failure.5 VMs support long-lived WebSocket connections, and the decentralized architecture means there's no central provider that can be pressured to shut you down.
This is niche. Most teams don't need censorship resistance. But if you're building a web3 real-time app, a privacy-focused messaging platform, or anything that needs to survive infrastructure takedowns, Aleph Cloud's model is worth understanding. The tradeoff is a smaller ecosystem, less tooling maturity, and more operational uncertainty than mainstream cloud providers.
| Platform | Type | WebSocket support | Ops overhead | Best for |
|---|---|---|---|---|
| Railway | PaaS | Native, full processes | Low | Most teams |
| Render | PaaS | Native, web services | Low | Prototyping |
| VKE | Managed K8s | Full containers | Medium-High | Cost + control |
| LKE | Managed K8s | Full containers | Medium-High | Performance |
| Aleph Cloud | Decentralized VM | VM-based | Medium | Censorship resistance |
The two PaaS options (Railway, Render) win on developer experience — no Kubernetes, no ingress config, just deploy and go. The two K8s options (VKE, LKE) win on control and cost at scale — you're trading ops complexity for unlimited flexibility. Aleph Cloud is its own category, trading mainstream reliability for decentralization.
