Mocky versus G2
Compare	Mocky	G2
Verdict	Depends	Depends
Best for	Throwaway API stubs for demos	B2B software buyers shortlisting tools
Who it's not for	Anything production or long-lived . reliability questioned	Vendors without five-figure budgets
Privacy	No known vulnerabilities disclosed, but no security page exists and the free service has been abused in GRU-linked phishing campaigns.^⁸	No public security page found; UpGuard reports no phishing; G2's own DPA references a past data breach.
Support quality	No support evidence found	Trustpilot and BBB complaints about G2's service
Public sentiment	The few G2 reviewers rate it 4.0/5 and love the simplicity, while Reddit threads question whether the service is still reliable.^¹	Buyers find G2 useful for breadth, but sentiment on G2's own service skews negative on Trustpilot and Redditors weigh it against Capterra and Trustpilot.
Biggest gotcha	Mock URLs aren't private . never embed real credentials or personal data.^⁴	Vendor contracts are negotiated and opaque; budget five figures annually before committing.
