filebin.ca

What It Is

filebin.ca is a lightweight file upload and sharing service focused on “upload a file, share a link.” It supports any file type. According to the site, users can get permanent download links and set expiration times, and it can be used without an account. Compared with traditional cloud drives, it feels more like a file relay service for temporary sharing, script automation, and AI Agent workflows.

Core Features and Developer Capabilities

Basic features include file uploads, public link sharing, reading file metadata, listing account files, and deleting files. Anonymous users can upload through the browser, but are limited to 10 MB per file, 20 uploads per hour, and files expire after 30 days; Turnstile verification is also required. After logging in, users can raise these limits and keep uploaded content, although the text does not specify the exact quotas.

Its developer tooling is the main highlight. filebin.ca provides a REST API, pbca CLI, and MCP server. The REST API uses Bearer API Keys and supports scopes such as file:read, file:create, and file:delete. The CLI can run upload, get, list, and delete commands. MCP allows clients such as Claude Desktop, Cursor, and Windsurf to manage files directly. API Keys also support audience-bound usage, making them valid only for filebin.ca.

Pricing and Security

The page clearly states free file upload & sharing, but does not disclose paid plans, enterprise editions, SLAs, or payment methods. For upload limits, API-key REST uploads allow up to 25 MiB per file, while MCP is limited to 8 MiB due to JSON-RPC/base64 overhead. On the security side, it supports OAuth 2.1 + PKCE, DPoP-bound keys, audience-bound tokens, and the ability to revoke keys or connected apps in a pastebin.ca account. However, the text does not mention encryption, data residency, audit logs, or compliance certifications.

Pros, Cons, and Who It’s For

The main advantages are ease of use, no account requirement, and a complete developer toolchain. It is especially suitable for automation scripts, temporary file distribution, and AI Agent file-handling workflows. The drawbacks are limited enterprise-focused information: there is no mention of team permissions, organization management, auditing, compliance, support channels, or clearly defined commercial plans. Anonymous and API upload limits also make it unsuitable for large file transfers.

China Access and Alternatives

The text does not provide information about access from mainland China, payment options, or local nodes, so its China accessibility should be considered unknown. If you need stable domestic access and local payment options, you may compare it with Alibaba Cloud Drive, Lanzou Cloud, and similar services. For international file sharing and collaboration, Dropbox, Google Drive, and WeTransfer are possible alternatives.
