About Filestash

Filestash began as a Dropbox-like file manager that speaks many storage protocols, including FTP, SFTP, S3, SMB, WebDAV and IPFS along with about twenty more. It has since grown into a wider file management platform built around three products: a web client for browsing files in a browser, a native client for syncing data to devices, and gateways that expose storage over other protocols.

Its architecture is plugin-driven, so anything beyond the lean core lives in a plugin and requirements are met by adding or writing plugins rather than forking. The web client is written in vanilla JavaScript, and APIs and gateways can expose data over SFTP, S3, FTP, WebDAV, MCP and AS2. Authentication integrations can go as far as delegating login to a WordPress site and using its roles for access control.

A workflow engine automates actions on files by chaining steps on events, ranging from Slack or email notifications to managed file transfer pipelines. Filestash is written in Go and released under the AGPL-3.0 license, and repository topics point to uses in document management and archiving.
