Pros & Cons
Hurl
Pros
Completely free and open source with no paid tiers or limits
Lightweight single binary with no scripting language or GUI required
Powerful built-in assertions make it a genuine API testing tool, not just a request runner
Plain-text format is easy to version control, review, and diff
Backed and actively maintained by Orange with a stable release history since 2020
Cons
Smaller plugin and template ecosystem compared to Postman or Insomnia
No polished graphical interface, which can be a barrier for non-technical testers
Steeper learning curve for complex chained scenarios compared to point-and-click tools
Limited built-in mocking or virtualization capabilities
Less mainstream brand recognition than established API tools like Postman
trumailo
Pros
Real SMTP handshake verification, not just syntax/MX checks, which catches more genuinely undeliverable addresses
Sub-10ms cached response times make it usable inline in a signup or checkout flow, not just for batch list cleaning
Provider-agnostic — works alongside SendGrid, Resend, Postmark, SES, Mailgun, and other ESPs rather than locking you into one
Free public beta tier with no credit card required, plus a 30-day money-back guarantee once paid plans launch
Cons
Specific paid-tier pricing isn't published — you have to sign up or contact sales to see numbers
Still in public beta (v0.5 per the company), so pricing, SLAs, and the feature set are subject to change
No independent third-party security certifications yet — SOC 2 and ISO 27001 are described as roadmap items, not current certifications
Company is small and self-described as a young/internal-tool-turned-product, so long-term track record is limited
