FTP, SFTP & WebDAV Tools
Browser-based tools for testing and debugging FTP, SFTP, FTPS, and WebDAV connections - no installation needed
Setting up an FTP or SFTP server usually means going back and forth between terminal commands, firewall rules, and client settings until things work. These tools let you test each piece individually from your browser - check if a port is open, verify TLS certificates, confirm which auth methods a server supports, or look up what a response code actually means.
They’re organized into four groups: connection testers for verifying server reachability across FTP, SFTP, FTPS, and WebDAV; security & inspection tools for checking certificates, host keys, TLS versions, and authentication methods; utilities for port checking, FTP command reference, URL parsing, and passive mode diagnostics; and object storage helpers for Amazon S3 and S3-compatible buckets - IAM policies, URIs and storage-class costs.
Connection Testers
FTP Connection Tester
Verify FTP server reachability, test credentials, and diagnose connection issues instantly.
SFTP Connection Tester
Test SFTP server connectivity with password or key-based authentication and view detailed results.
FTPS Connection Tester
Check FTPS (FTP over TLS) server connectivity and validate the TLS handshake and certificate chain.
WebDAV Connection Tester
Test a WebDAV server with a real PROPFIND request. Verify credentials, check DAV compliance level, and diagnose errors.
Security & Inspection
FTPS Certificate Checker
Inspect the TLS certificate of an FTPS server - expiry date, issuer, subject, and chain validity.
Open toolSFTP Host Key Fingerprint
Retrieve and display the SSH host key fingerprint of an SFTP server for identity verification.
Open toolFTP Anonymous Login Checker
Check whether an FTP server accepts anonymous logins - a common misconfiguration and security risk.
Open toolTLS Protocol Scanner
Detect which TLS versions (1.0, 1.1, 1.2, 1.3) and cipher suites an FTP/FTPS server supports.
Open toolSFTP Auth Method Checker
Discover which authentication methods an SFTP server accepts - password, public key, or keyboard-interactive.
Open toolWebDAV Certificate Checker
Inspect the TLS certificate of a WebDAV/HTTPS server - expiry, SANs, key size. Works with ownCloud and Nextcloud.
Open toolUtilities
FTP Port Checker
Check whether an FTP port (21, 22, 990, or custom) is open and accepting connections on a remote host.
Open toolFTP Response Code Lookup
Look up any FTP status code and get a plain-English explanation of what it means and how to resolve it.
Open toolFTP Server Banner Grabber
Retrieve the raw server banner sent on connection to identify the FTP server software and version.
Open toolFTP URL Parser / Builder
Parse an FTP URL into its components or build a valid FTP/SFTP/FTPS URL from host, port, path, and credentials.
Open toolFTP Command Reference
Browse all standard FTP commands with syntax, descriptions, and examples - searchable and filterable by category.
Open toolSFTP Command Reference
All OpenSSH sftp client commands with syntax and examples - get, put, reget, chmod, batch mode, and connection flags.
Open toolFTP Passive Port Range Checker
Scan a range of passive-mode ports on your FTP server to verify they are open and reachable through firewalls.
Open toolCloud Storage Price Calculator
Compare object-storage costs - S3 vs Backblaze B2 vs Wasabi vs Cloudflare R2 vs Google Cloud vs Azure - from your storage and egress.
Open toolObject Storage
S3 IAM Policy Generator
Build a least-privilege IAM user or bucket policy for a single S3 bucket - pick actions and a prefix, get the JSON.
Open toolS3 URI Parser & Builder
Convert between s3:// URIs, virtual-hosted and path-style HTTPS URLs and ARNs - parse one, or build all four.
Open toolS3 Storage Classes
Compare every S3 storage class - price, retrieval, minimum duration and use case - and estimate monthly cost for your data.
