VirtuProbe Studio
A request-testing tool like Postman, but built for protocols beyond HTTP — SMTP, IMAP, LDAP, DNS, SMB, Kerberos, and SQL databases — running entirely on your machine.

Description
Postman and Insomnia are great for testing a REST API, but the moment you need to test whether an email server accepts a connection correctly, whether an LDAP directory responds the way you expect, or whether a DNS record resolves properly, you're stuck reaching for a different tool for each protocol. VirtuProbe Studio is built specifically to cover that gap — one workbench that speaks HTTP, SMTP, IMAP, LDAP, DNS, SMB, Kerberos, and several SQL databases, with the ability to chain requests together across protocols.
Beyond basic requests, it includes a MITM proxy for mocking services, JavaScript and Groovy scripting for custom logic, fuzzing tools for security testing, and over 1,000 ready-made test chains to start from. Everything runs locally — no cloud sync, no data leaving your machine — which matters for the security researchers and infrastructure testers who are a core part of its audience.
💬 Our review
The short version: VirtuProbe fills a real gap that Postman and Insomnia don't cover — multi-protocol testing beyond plain HTTP — and the local-only execution model is a genuine advantage for security-sensitive testing work.
Postman and Insomnia dominate REST/GraphQL API testing but don't natively handle SMTP, LDAP, Kerberos, or raw SQL protocol testing the way VirtuProbe does, which makes it specifically useful for QA engineers testing mail/identity infrastructure or security researchers doing protocol-level penetration testing. The free tier (HTTP, DNS, SMTP, no account) is a real, usable starting point, and paid tiers at €19-49/month add the security-focused protocols and features. The tradeoffs: it's not open source, pricing is in EUR only which may add friction for some, and its market presence is much smaller than the established API-testing tools, so community resources and tutorials are scarcer.
