Built for developers who'd rather ship than configure storage.

Independently built and operated · based in Stockholm, Sweden · in production since 2026 · support@@postfile.net

PostFile is a file hosting API. You send a file, you get back a permanent public CDN URL. No S3 buckets, no IAM roles, no CloudFront distributions. One API call, one URL.

PostFile exists because the same problem kept showing up across projects: "I need to upload a file and get a URL." Every time, it meant setting up object storage, configuring permissions, wiring up a CDN, and writing upload logic. For what should be a one-liner.

How it works

Files are stored on Backblaze B2 (the same infrastructure behind many large-scale storage providers) and served through Cloudflare's CDN network. This combination gives you:

• Global delivery: files cached at 300+ edge locations worldwide
• Zero egress fees: Cloudflare's Bandwidth Alliance means free downloads
• No automatic expiry: files stay until you delete them or configure expiry
• Redundant storage: B2 stores data across multiple drives and facilities

The stack

Why PostFile exists

Most file hosting solutions are either too complex (S3 + IAM + CloudFront), too limited (free tiers with expiring links), or too expensive for what they offer. PostFile sits in the middle: simple enough for a weekend project, reliable enough for production.

The API is designed for developers and automation workflows. If you use Zapier, n8n, Pipedream, Make, or any tool that can make HTTP requests, PostFile works out of the box. PostFile is approved as a public Zapier app, has a verified n8n Cloud community node, and includes a native Pipedream component for drag-and-drop file uploads.

How we operate

PostFile is run independently. No VC funding, no growth-at-all-costs roadmap, no acquisition exit timeline that ends with the API getting deprecated.

• Permanent URLs. Every URL we issue keeps working. No silent expiry, no rotating identifiers. If we ever change a URL format, every existing URL will keep resolving.
• Flat, monthly pricing. $0 / $9 / $29. No annual contracts, no proration tricks, no "contact sales" tier hiding behind the highest plan.
• No credit card on the free tier. 20 uploads per month instantly, 1000 per month after email verification, 50 MB per file, real CDN delivery. Enough to evaluate the product on a real project, not a demo.
• No billing on failed uploads. 4xx responses don't count against your quota.
• Single human inbox. Every email to support@@postfile.net reaches a person who can change the code that day.
