In-depth overview
Cloudflare R2
Best object storage — zero egress fees make it dramatically cheaper than S3 for most use cases
Amazon S3's business model charges you for every byte that leaves their infrastructure. For an application that stores and serves large files — images, videos, documents, software downloads — egress charges can exceed storage costs by 10x or more. Cloudflare R2 eliminates egress fees entirely. You pay for storage ($0.015/GB/month) and operations, but zero for data transfer out.
The S3-compatible API means you can use any S3 SDK or tool without modification. Switch your AWS credentials for Cloudflare's, update the endpoint URL, and your existing code works. The JavaScript and Python S3 SDKs, tools like rclone, s3cmd, and Cyberduck — all work without changes.
The integration with Cloudflare Workers is a significant advantage for teams in the Cloudflare ecosystem. An R2 binding in a Worker gives you bucket access without any HTTP round trips. For image resizing, file serving with access control, or processing uploads, this creates a clean serverless architecture without egress costs.

Best all-in-one backend for new projects in 2026
Supabase made a bet in 2020 that the market was tired of proprietary NoSQL databases and Firebase lock-in. That bet paid off. In 2026 it is one of the fastest-growing developer tools companies in the world, and the go-to backend for new projects that want comprehensive infrastructure without stitching together a dozen services.
The foundation is just Postgres. There is no proprietary query language, no special SDK required. You can use any Postgres-compatible ORM — Drizzle, Prisma, SQLAlchemy, ActiveRecord — and standard pg clients. Real Postgres means pgvector for embeddings, pg_cron for scheduled tasks, and every ecosystem extension works.
On top of Postgres, Supabase auto-generates a REST API from your schema using PostgREST. Every table gets CRUD endpoints automatically. Row Level Security policies written in SQL control what each authenticated user can read and write — no custom authorization middleware required. The JavaScript SDK handles these policies transparently, enabling your frontend to query the database directly without a bespoke API layer for most use cases.

Choose Cloudflare R2 if
Any application that serves files to end users — images, videos, downloads — where S3 egress fees are material
Avoid Cloudflare R2 if
Applications deeply integrated with AWS services that benefit from S3's native integrations with Lambda and CloudFront
Choose Supabase if
New projects that want a full-featured backend without managing five separate services — especially apps that need auth, file storage, and realtime built in from day one
Avoid Supabase if
Projects that need maximum database performance tuning, enterprise compliance from day one, or teams already deeply invested in a different database provider
Production tips
Cloudflare R2 tips
- 1.Use a public R2 bucket with a custom domain for serving static assets — zero egress means no CDN cost
- 2.R2 + Workers + Images for automatic resizing is a cost-effective Cloudinary alternative
- 3.The `aws-sdk-v3` S3 client works with R2 — just set the endpoint to your R2 account URL
Supabase tips
- 1.Use Drizzle ORM with Supabase for type-safe queries that still allow raw SQL when needed
- 2.Enable pgvector for storing and querying AI embeddings directly in your database
- 3.Supabase CLI `supabase db diff` generates migration files automatically from schema changes
