If you rent GPUs to render video, run image models or train something, Runpod is usually one of the first names you hear. It's also the one I use. But it isn't the only option, and depending on what you're doing, another cloud might be cheaper, simpler or a better fit.
Let me be upfront before we start.
Runpod is the GPU cloud I render my AI videos on, including my 100 day videos and Nero clips.
I haven't used any of the alternatives in this post myself. Everything I say about Vast.ai, Lambda, Modal, DigitalOcean and TensorDock comes from their official pricing pages and docs, which I checked on October 31, 2026. Where I'm sharing my own experience, I'll say so. I don't speak for any of these companies.
A quick naming note: the company now styles its name "Runpod". You'll still see "RunPod" in a lot of places, including older posts, so I use both here.
The quick answer
- Vast.ai if you want the lowest possible price and you're fine with a marketplace of hosts and prices that move.
- Lambda if you want a simple, traditional GPU cloud with fixed hourly prices, aimed at AI training.
- Modal if you write Python and want serverless GPUs that scale to zero, billed by the second.
- DigitalOcean GPU Droplets if you already use DigitalOcean or want a mainstream cloud with reserved pricing.
- TensorDock if you want full virtual machines with root access, including Windows, from a marketplace of vetted hosts.
- Stay on Runpod if you want both on demand Pods and Serverless in one account, with a wide range of GPUs from cheap consumer cards to B300s.
If you've already narrowed it down to two, I've written a full head to head: RunPod vs Vast.ai.
Price comparison table
These are the listed hourly prices for one GPU on each official page, checked October 31, 2026. They don't include storage, CPU, RAM or tax unless the provider bundles them. Prices change often, so check before you rent.
| GPU | Runpod Pods (Secure Cloud / Community Cloud) | Lambda (1x instance) | Modal (serverless) | DigitalOcean (on demand) | TensorDock (from) |
|---|---|---|---|---|---|
| H100 SXM | $3.99 / $2.69 | $4.29 | $3.95 (H100) | $4.41 (H100) | $2.25 |
| H100 PCIe | $2.89 / $1.99 | $3.29 | |||
| A100 80GB | $1.79 / $1.39 (SXM) | $2.79 per GPU on 8x only | $2.50 | $1.80 (A100 SXM4) | |
| L40S | $1.09 / $0.79 | $1.95 | $1.57 | ||
| RTX 6000 Ada | $0.99 / $0.74 | $1.57 | |||
| RTX 4090 | $0.89 / $0.34 | $0.35 | |||
| L4 | $0.59 / $0.44 | $0.80 |
Blank cells mean I didn't see that GPU listed as a single GPU on the page I checked. Modal's prices are converted from its per second rates, and CPU and memory are billed on top. TensorDock's figures are its "from" prices on the homepage. Vast.ai isn't in the table because its prices are set live by each host, so there's no fixed list price to quote.
1. Vast.ai: the marketplace option
Vast.ai is a GPU marketplace. Independent hosts and data centers list their machines, and you pick an offer. Its pricing page says it has 40+ data centers and 68+ GPU types, with three ways to rent:
- On demand: fixed price for the life of the instance.
- Interruptible: often 50% or more cheaper, but your instance can be paused when someone pays more.
- Reserved: commit for 1, 3 or 6 months for a lower price.
Billing is per second with no minimum hours. You pay with prepaid credits, by card through Stripe or by crypto. The billing docs list a few things to watch:
- Storage is charged as long as the instance exists, even when it's stopped.
- Bandwidth is charged per byte, and the rate depends on the host.
- When your balance hits zero, instances stop, and without a saved card they can be scheduled for deletion.
- Spent credits aren't refundable. Unspent card credits usually are, crypto isn't.
Best for: people who want the cheapest GPU hours and don't mind comparing offers. On the day I checked, the RTX 4090 page showed no current offers, which is a good reminder that marketplace availability moves around.
2. Lambda: a traditional GPU cloud
Lambda is a GPU cloud built mainly for AI training and inference. Prices are fixed per hour. On the day I checked, single GPU instances included:
- H100 SXM: $4.29/hour
- H100 PCIe: $3.29/hour
- A100 40GB (SXM or PCIe): $1.99/hour
- A10: $1.29/hour
- RTX A6000: $1.09/hour
- B200: $6.99/hour
The 8 GPU machines cost less per GPU: 8x H100 SXM was $3.99 per GPU per hour, and 8x A100 80GB was $2.79 per GPU per hour. Lambda also sells 1-Click Clusters of 16 GPUs or more.
Lambda's billing docs say instances are billed in one minute increments, invoices go out weekly, and there are no egress fees. Sales tax is added where it applies. New accounts start with an instance quota, so you may need to ask for more if you want big machines straight away.
Best for: teams training models who want a straightforward cloud with predictable prices. I didn't see consumer cards like the RTX 4090 in Lambda's list, so it's less of a fit for cheap hobby renders.
3. Modal: serverless GPUs for Python
Modal works differently from Runpod Pods. Instead of renting a machine and logging in, you write Python, and Modal runs your function in containers on GPUs when it's called. It scales to zero when nothing is running.
Modal lists prices per second. Converted to hourly, the GPU rates on the day I checked were about:
- B200: $6.25/hour
- H100: $3.95/hour
- A100 80GB: $2.50/hour
- L40S: $1.95/hour
- L4: $0.80/hour
- T4: $0.59/hour
CPU and memory are billed separately on top. The Starter plan is $0 plus compute and includes $30 of compute a month, for up to 3 seats. The Team plan is $250/month plus compute and includes $100 of compute a month. Two things to know: containers stay warm for 60 seconds after the last request by default, and that warm time is billed. And picking a specific region or non-preemptible capacity costs more (Modal lists multipliers for both).
Best for: developers building an app or API that needs GPUs on demand. If you just want a machine to run ComfyUI on for an evening, a Pod style service is simpler.
Runpod has its own Serverless product too, so if serverless is the reason you're looking, it's worth comparing. Runpod's Serverless prices on the day I checked included $0.75/hour for 24GB cards (L4, A5000 or 3090), $1.34/hour for a 4090 PRO and $5.39/hour for an H100 PRO.
4. DigitalOcean GPU Droplets: a mainstream cloud
DigitalOcean is a general cloud provider that added GPU Droplets. Its GPU pricing page says new pricing took effect on August 1, 2026. On demand prices on the day I checked included:
- H100: $4.41 per GPU per hour
- H200: $4.47 per GPU per hour
- L40S: $1.57 per GPU per hour
- RTX 6000 Ada: $1.57 per GPU per hour
- RTX 4000 Ada: $0.76 per GPU per hour
- AMD MI300X: $2.59 per GPU per hour
DigitalOcean also lists 12 month reserved prices (for example, H100 at $3.26 per GPU per hour) and spot prices for some newer GPUs, which can be interrupted.
Watch the billing rules. GPU Droplets are billed per second with a 5 minute minimum, and a Droplet that's powered off is still billed until you destroy it. DigitalOcean's page also says it doesn't offer refunds. On the plus side, each GPU Droplet comes with a large data transfer allowance.
Best for: people already running apps on DigitalOcean, or teams who want reserved capacity from a big, familiar provider.
5. TensorDock: full VMs from vetted hosts
TensorDock is a marketplace too, but it rents full KVM virtual machines with root access from independent hosts it vets. Its homepage lists 45 GPU models in 100+ locations, Windows 10 support and no ingress or egress fees. The "from" prices on the day I checked were:
- H100 SXM5: from $2.25/hour
- A100 SXM4: from $1.80/hour
- RTX 4090: from $0.35/hour
- Consumer GPUs: from $0.12/hour
You can start with $5. One catch, from TensorDock's own page: servers are deleted when your balance reaches zero, so keep an eye on your credit.
Best for: people who want a full VM, including Windows, at marketplace prices.
Why I still use Runpod (my real reasons)
This part is my own experience. Runpod is the GPU cloud I render my AI videos on, including my 100 day videos and Nero clips. I haven't tested the others, so I can't tell you any of them is better or worse in daily use.
Here's what Runpod's official pages say it offers, which is why I'd suggest trying it before switching:
- Two clouds in one account. Secure Cloud and the cheaper Community Cloud for Pods, plus Serverless for APIs.
- A wide range of GPUs. From an RTX A5000 at $0.27/hour (Secure Cloud) up to B300s, in 30+ regions.
- Per second billing with no ingress or egress fees, according to the Pod pricing docs.
And the catches, from the same docs:
- You need at least one hour of credit in your balance to deploy an on demand Pod.
- If your balance hits $0, Pods stop, and a Pod without a network volume can be terminated, which means your data is gone. Runpod says Pods aren't meant for long term storage.
- Storage costs money even when a Pod is stopped: volume disk is $0.10/GB/month while running and $0.20/GB/month while idle.
How to choose
Ask yourself three questions:
1. Do you want a machine or a function? A machine you log into: Runpod Pods, Vast.ai, Lambda, DigitalOcean or TensorDock. A function your code calls: Modal or Runpod Serverless. 2. Is lowest price or predictability more important? Marketplaces (Vast.ai, TensorDock, Runpod Community Cloud) are cheapest but vary by host. Fixed price clouds (Lambda, DigitalOcean, Runpod Secure Cloud) cost more but behave the same every time. 3. What happens to your files when your balance runs out? Every provider here has rules about stopping or deleting machines. Read them before you put work you care about on any of them.
Try Runpod yourself
If you want to start with what I use, here's my link.
๐ Sign up for Runpod here (Referral link)
Reminder: that's my referral link. If you sign up and spend on Runpod, I get Runpod credits, at no extra cost to you.
Here's how Runpod's own referral program works, from its docs on October 31, 2026: the referrer earns credits worth 3% of Pod spend and 5% of Serverless spend for the first 6 months. A referred user needs to sign up with Google sign in, be new to Runpod and load $10. Runpod then gives that user a one time credit, which is random between $5 and $500 outside Europe (most people get $5, and about 96% get $10 or less) and a fixed $5 in Europe. That bonus comes from Runpod's program, not from me.

FAQ
What is the cheapest RunPod alternative?
On listed prices, the marketplaces usually come out cheapest. TensorDock listed an RTX 4090 from $0.35/hour on October 31, 2026, close to Runpod's Community Cloud price of $0.34/hour. Vast.ai's prices are live and set by hosts, so check its site for today's offers.
Is Lambda cheaper than Runpod?
Not on the single GPU prices I checked. Lambda listed an H100 SXM at $4.29/hour, against $3.99/hour on Runpod Secure Cloud and $2.69/hour on Community Cloud. Lambda's 8 GPU machines are cheaper per GPU, at $3.99 per H100 per hour.
Is Modal an alternative to Runpod?
It's an alternative to Runpod Serverless more than to Runpod Pods. Modal runs your Python code on GPUs on demand and bills per second, with CPU and memory charged on top.
Do these providers charge for data transfer?
Runpod, Lambda and TensorDock say they don't charge ingress or egress fees. Vast.ai bandwidth is charged per byte at rates set by each host. DigitalOcean includes a data transfer allowance with GPU Droplets.
