DigitalOcean Spaces vs S3 vs files.link: A Three-Way Comparison
DigitalOcean Spaces vs AWS S3 vs files.link: pricing, CDN, API compatibility, and developer experience compared with real numbers.
Three Approaches to Object Storage
DigitalOcean Spaces, AWS S3, and files.link represent three different points on the object storage spectrum: simple and affordable, infinitely scalable, and developer-first with managed CDN.
DigitalOcean Spaces is S3-compatible object storage with a flat $5/month price that includes 250 GB of storage and 1 TB of outbound bandwidth. It appeals to developers who want predictable pricing without AWS complexity.
AWS S3 is the industry standard. It offers unmatched durability (11 nines), dozens of storage classes, and deep integration with 200+ AWS services. The pricing is granular — you pay separately for storage, requests, and data transfer.
[files.link](/digitalocean-spaces-alternative) is a managed file storage and CDN service. It provides a REST API with prepaid credit-based billing and handles CDN delivery automatically.
All three can store and serve files. The right choice depends on your scale, budget, and how much infrastructure you want to manage.
Pricing Comparison
Pricing is where these services diverge most sharply. Let us compare costs for a realistic workload: 100 GB of storage with 500 GB of monthly outbound transfer and 1 million GET requests.
| Cost Component | DigitalOcean Spaces | AWS S3 (Standard) | files.link |
|---|---|---|---|
| Base price | $5/month flat | No base price | Prepaid credits (start at $5) |
| Storage (100 GB) | Included in $5 | $2.30/month | Included in credits |
| Outbound transfer (500 GB) | Included (1 TB free) | $45/month (first 10 TB at $0.09/GB) | Included in credits |
| GET requests (1M) | Included | $0.40 | Included in credits |
| PUT requests (10K) | Included | $0.05 | Included in credits |
| CDN included | Yes (built-in CDN) | No (CloudFront is separate) | Yes (global CDN, 450+ locations) |
| Estimated monthly total | $5 | ~$48 | Credit-based (prepaid) |
CDN and Performance
DigitalOcean Spaces CDN
Spaces includes a built-in CDN at no extra cost. It serves content from DigitalOcean's edge network, which is smaller than CloudFront but covers major regions. You enable it with a toggle — no separate configuration needed.
The CDN URL format is straightforward: https://your-space.region.cdn.digitaloceanspaces.com/file.jpg. Custom domains are supported via CNAME records.
Performance is adequate for most use cases, but DigitalOcean's edge network has fewer locations than CloudFront. For applications with users concentrated in North America and Europe, the difference is negligible. For global distribution to Asia, South America, and Africa, CloudFront has better coverage.
AWS S3 + CloudFront
S3 itself has no CDN. Files are served from a single region. To add CDN delivery, you set up a CloudFront distribution — which means configuring an origin, cache behaviors, SSL certificates, and optionally Origin Access Control for private buckets.
CloudFront has 450+ edge locations and is the largest CDN by geographic coverage. Performance is excellent globally. But the setup takes 30-60 minutes, and you pay separately for CloudFront data transfer ($0.085/GB for the first 10 TB).
files.link CDN
CDN file hosting is built in. Every file uploaded to a public folder gets a CDN URL automatically. No CDN configuration, no cache behavior setup, no Origin Access Control. Private files are served via signed URLs with automatic expiration.
The CDN spans 450+ edge locations globally — but you do not configure or manage it. Upload a file, get a CDN URL.
API and S3 Compatibility
DigitalOcean Spaces implements the S3 API. Your existing S3 code works with Spaces by changing the endpoint:
import { S3Client } from "@aws-sdk/client-s3";
const s3 = new S3Client({
endpoint: "https://nyc3.digitaloceanspaces.com",
region: "us-east-1", // Required by SDK but ignored by Spaces
credentials: {
accessKeyId: "YOUR_SPACES_KEY",
secretAccessKey: "YOUR_SPACES_SECRET",
},
});
// Use standard S3 commands — PutObject, GetObject, etc.Not all S3 features are supported. Missing features include S3 Select, S3 Batch Operations, S3 Object Lock, and some storage classes. For standard put/get/delete/list operations, compatibility is excellent.
AWS S3 is the original — full API surface, all features, all storage classes. Every S3-compatible tool and library works natively.
files.link uses its own REST API rather than the S3 API. This is a deliberate choice: the API is simpler and higher-level than S3's.
# Upload a file
curl -X POST https://api.files.link/v1/files \
-H "Authorization: YOUR_API_KEY" \
-F "[email protected]" \
-F "folderId=FOLDER_ID"
# Response: { "cdnUrl": "https://cdn.files.link/p/...", ... }If S3 API compatibility is a hard requirement (e.g., existing tools like rclone, s3cmd, or Terraform that speak S3), check whether your tools support REST APIs as an alternative. If you want a simpler API and do not need S3 compatibility, files.link's REST API is faster to integrate.
Developer Experience
DigitalOcean Spaces:
- Simple dashboard — create a Space in 30 seconds
- S3-compatible API means existing tools work
- Flat pricing eliminates billing surprises
- Limited features compared to S3 (no lifecycle policies with Glacier, no S3 Select)
- Good documentation, smaller community than AWS
AWS S3:
- Extremely powerful but complex — hundreds of configuration options
- IAM policies for access control (powerful but verbose)
- Deep integration with Lambda, SQS, SNS, Step Functions, and other services
- Billing is complex — multiple meters, hard to predict costs
- Largest community and most third-party tool support
files.link:
- REST API — no SDK required, works with
curlor any HTTP client - Project and folder hierarchy for organizing files
- Automatic CDN URLs — no separate CDN configuration
- Developer-focused file storage with built-in signed URLs for private content
- Focused on the core workflow: storing and serving files with minimal configuration
The experience gap is real: creating a DigitalOcean Space and uploading a file takes under a minute. Doing the same with S3 (including IAM credentials, bucket policy, and optionally CloudFront) takes 30-90 minutes. files.link falls in between — account creation and API key setup in 2-3 minutes, then immediate uploads.

When to Choose Each
Choose DigitalOcean Spaces when:
- You want simple, predictable pricing for moderate storage needs
- S3 API compatibility matters (existing tools, libraries, or migration from S3)
- You are already on DigitalOcean and want to keep everything in one platform
- You need basic object storage with CDN and do not need advanced features like lifecycle transitions or event notifications
- Your workload fits within the $5/month tier (250 GB storage, 1 TB bandwidth)
Choose AWS S3 when:
- You need advanced features: lifecycle policies, S3 Select, event notifications, S3 Batch Operations
- You are in the AWS ecosystem and need S3 triggers for Lambda, SQS, or Step Functions
- You need multiple storage classes for cost optimization (Glacier for archives, Intelligent-Tiering for unpredictable access)
- You operate at very large scale where per-GB pricing beats flat-rate pricing
- Compliance requirements demand specific regions or certifications that only AWS provides
Choose [files.link](/digitalocean-spaces-alternative) when:
- You want file storage with a built-in CDN and zero infrastructure management
- You prefer a simple REST API over the S3 protocol
- Predictable billing matters — prepaid credits mean no surprise invoices
- You need automatic signed URLs for private files without managing signing keys
- You are building a web application and want the fastest path to serving files to users
The honest bottom line: DigitalOcean Spaces offers the best value for straightforward object storage with predictable pricing. AWS S3 is unmatched for large-scale, feature-rich infrastructure. files.link is the fastest path from "I need to store and serve files" to actually doing it, with CDN delivery included out of the box.
