Serv-U FTP Server vs Syncplify AFT!

Serv-U FTP Server provides FTP and FTPS file transfers for organizations, with web and mobile interfaces for viewing, uploading, and downloading files. The FTP Server edition supports IPv4 and IPv6; an edition comparison also lists HTTP. SSL/TLS encrypts transfers. Users can pause or resume multiple and large exchanges, including files larger than 3 GB. Administrators can create users and groups, manage permissions and bandwidth, and review transfer details in a management console. They can set transfer ratios and quotas, limit concurrent sessions, and use IP blocking, reverse DNS options, and anti-hammering controls. Automation can move or delete files after transfer, or disable or reset credentials after a specified number of days. The optional Serv-U Gateway is described as keeping data out of the DMZ and helping meet listed compliance requirements. SolarWinds positions this edition for small businesses and project teams with fewer users and domains on one server. It has no free plan; the listed price is $55 a month, billed annually, and a 14-day trial is available.

Syncplify AFT! automates file-transfer workflows through SyncJS, an ECMAScript 5.1-based scripting engine with more than 200 file-transfer functions. Scripts use one virtual file system for local files, SFTP, AWS S3, Azure Blob Storage, and Google Cloud Storage. Jobs can start on Cron-compatible schedules, filesystem events, or REST API triggers. The library handles CSV and XML parsing, HMAC and PGP operations, SQL, AMQP, HTTP/S, and notifications to Slack, Teams, Telegram, Twilio, and email. AFT! keeps searchable indexed job logs and stores credentials and API keys in an encrypted secrets store for runtime retrieval. It runs on Windows and Linux as a statically linked binary for bare metal, virtual machines, or Docker. A VS Code extension adds language-server features, autocomplete, documentation, and an MCP server. The product costs $99 or VM. A 15-day trial requires no credit card.
