For a small AzuraCast internet radio station that also sends audio to YouTube Live, start with at least 2 GB of RAM and 20 GB of disk—but treat that as a floor, not a promise of smooth performance. AzuraCast’s hobby recommendation is 4 CPU cores, 4 GB of RAM and at least 40 GB of disk. Choose a VPS that meets the resources your workload needs, then compare the full recurring cost, including outbound transfer and any extras. DigitalOcean’s advertised $4/month starting example and its $7/month Premium 1 GB example are both below AzuraCast’s stated RAM minimum, so neither entry price alone makes a suitable recommendation.
What VPS size should you choose?
AzuraCast publishes a minimum of 2 GB RAM and 20 GB disk for 64-bit x86_64/amd64 or ARM64 servers, while warning that this minimum does not guarantee perfect operation. For hobby use, its recommendation is 4 CPU cores, 4 GB RAM and at least 40 GB disk. These are AzuraCast’s general requirements, not a benchmark for every combination of radio software, YouTube encoding and audience traffic. See AzuraCast’s current requirements.
| Starting point | AzuraCast guidance | How to use it |
|---|---|---|
| Minimum | 2 GB RAM, 20 GB disk; 64-bit x86_64/amd64 or ARM64 | A published floor only; operation is not guaranteed to be perfect. |
| Hobby recommendation | 4 CPU cores, 4 GB RAM, at least 40 GB disk | A more prudent target for a small station, subject to the stream and listener workload. |
Disk needs depend heavily on the size of the music library. Leave room for the application and upgrades as well as audio files. RAM also matters: AzuraCast identifies its database and PHP processes as important memory consumers, so a 1 GB instance is not a sensible shortcut just because its advertised price is low. AzuraCast’s scaling guide explains the workload considerations.
Which low-cost VPS providers are worth comparing?
AzuraCast names Linode (Akamai), Vultr and DigitalOcean among its one-click installer options. That establishes deployment choices, not a price or performance ranking. The available current price examples here are for DigitalOcean; compare suitable plans from all providers directly before buying, because plan specifications and prices can change.

| Provider or plan example | Published details in the cited source | Fit for AzuraCast |
|---|---|---|
| DigitalOcean shared CPU starting example | From $4/month | The cited starting price is below AzuraCast’s 2 GB RAM minimum; the specific starting configuration is not established here as suitable. |
| DigitalOcean Premium shared CPU entry example | $7/month; 1 GB RAM, 1 vCPU, 25 GB NVMe and 1,000 GB transfer | Below AzuraCast’s stated RAM minimum, despite having more than 20 GB of disk. |
| Linode (Akamai) and Vultr | Named by AzuraCast as one-click installer choices; comparable suitable-tier prices are not established here. | Check current plans that meet the resource target and compare total costs before choosing. |
DigitalOcean’s current plan page lists the cited entry examples, but the least expensive listing is not the same as the best fit for this job. Check DigitalOcean’s VPS plans and confirm the selected plan’s resources and billing details. DigitalOcean’s pricing documentation says bundled CPU Droplet billing has a 60-second or $0.01 minimum and a 672-hour monthly cap; verify that this applies to the specific plan and billing arrangement you choose. DigitalOcean Droplet pricing details.
Compare the full cost, not just the headline rate
- Memory and disk: Confirm the actual RAM and usable storage against AzuraCast’s requirements, allowing room for your library and upgrades.
- CPU allocation: Shared CPU plans can vary in sustained performance. Compare the allocation and terms; no comparative performance test is established here.
- Outbound transfer: The server must send the YouTube stream continuously, and listener traffic can add to the load and transfer. Check included bandwidth and overage charges rather than assuming the allowance is sufficient.
- Add-ons: Include any charges for backups, IPv4 or other extras in the monthly total.
- Region and network: Choose a location and network that work for your station’s audience and YouTube ingest, but do not infer a reliability or regional advantage without provider-specific evidence.
- Operations: A VPS requires deployment, updates and troubleshooting. Account for that time as well as the rental price.
How the VPS, radio station and YouTube stream fit together
AzuraCast is free radio-management software installed on a VPS or another server. It can schedule station audio and accept live-DJ connections. The YouTube output is a separate path: the station’s audio is packaged into a live video stream, commonly with a still image or other visual, and sent to YouTube Live using an encoder. The VPS therefore needs to handle the radio service and the chosen output workflow.

A simple audio program paired with a static image is a lighter video-processing task than generating complex or high-resolution video, but the available sources do not benchmark that specific setup. If you add video composition or encoding on the same VPS, assess the actual workload rather than assuming AzuraCast’s radio requirements cover it. Listener delivery can also change the load: AzuraCast notes that delivering audio to listeners is often less CPU-intensive than transcoding, but capacity still depends on the workload. There is no defensible listener-count ceiling for an unspecified VPS configuration. Read AzuraCast’s scaling guidance.
Configure the YouTube Live encoder
YouTube recommends RTMPS for live ingest. For an H.264 stream at 720p and 30 frames per second, YouTube’s recommended video bitrate range is 3–8 Mbps. Its encoder guidance calls for constant bitrate (CBR) and a 2-second keyframe interval, not exceeding 4 seconds. These are encoder settings for the cited format, not a guarantee that every network or VPS can sustain them. Check YouTube’s current encoder settings guidance.

Live-DJ contribution
AzuraCast’s streaming-software guide covers free, open-source broadcast clients including Mixxx and BUTT, and recommends Icecast mode for its setup. Use the client settings documented for your station and keep broadcaster ports reachable for remote DJs. AzuraCast warns that a reverse proxy such as Cloudflare can prevent direct connections to broadcaster ports; that does not mean a proxy cannot be used for the web interface, but the web route and broadcast ports need to be treated separately. See AzuraCast’s streaming software instructions.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common problems and what to check
- The service struggles on a very small VPS: Check RAM first against AzuraCast’s 2 GB minimum, then review CPU load and disk use. The minimum itself is not a guarantee of perfect operation.
- The music library fills the disk: Measure library storage, preserve room for the application and upgrades, and select a plan with enough usable disk.
- YouTube reports unstable stream health: Check that the VPS has sufficient outbound capacity, confirm the selected bitrate and encoder settings, and test the stream while monitoring health.
- A remote DJ cannot connect: Verify the station’s Icecast client configuration and that the broadcaster port is reachable. If a reverse proxy is involved, check whether it is interfering with direct broadcaster connections.
- The bill exceeds the advertised plan price: Review transfer allowances and overages, backups, IPv4 and other extras, plus the billing terms for the exact VPS plan.
- You need a listener capacity estimate: Do not infer one from the VPS price or RAM alone. AzuraCast says capacity varies by workload; assess the actual station and encoding configuration.
Or let it run in the cloud
If your goal is simply to keep uploaded programming live on YouTube, StreamNeo is a cloud alternative to maintaining a radio stack and encoder on a VPS: upload a recording or build a playlist, add your YouTube stream key once, and go live. It loops uploaded videos to YouTube; it does not broadcast from a camera. Nothing has to stay on at home, and there is no VPS to size for this workflow. Your upload streams as made, up to 4K 60fps, at one price per slot. If YouTube drops the stream, StreamNeo automatically recovers. The first day is free with no card; one free day is available per account. Monthly pricing is $9.99 per month.
