Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
API mocking.
Define arbitrary API routes and response handlers from a CLI or config file. Extend any HTTP service with new routes. Handlers can be shell scripts. Supports conditional responses and middleware. Define test assertions with integration into Go for programmatically adjusting tests.
Only provides builds for macOS and Linux even though it’s written in Go and could offer more.
Event driven file transfer server.
Modern file transfer server with SFTP, HTTPS, WebDAV, REST API frontend. Supports various storage backends from S3 to filesystem, CryptFS and SFTP. Virtual folders allow syncing and mapping between backends which can be shared by different users. Web UI for file management.
Some features are enterprise only (it’s based on an open core model) e.g. multi-node clustering, automated workflows based on file events, etc.
