Questions

Questions about switching.

What is the best Sintra alternative?

It depends on why you’re leaving. For control and spending limits, Royak. For phone calls and chat apps, Lindy. For building custom agents, Relevance AI.

Is there a free Sintra alternative?

Royak has an ongoing Free plan with 1,000 credits a month. Lindy gives $50 in trial credits that last 7 days. Relevance AI has retired its free plan for new sign-ups.

Which alternative is safest for my accounts?

Royak: every write waits for your approval, spending is capped before each call, and your keys never reach the AI. See the Security page.

Can I move my Sintra workflows?

None of these tools import Sintra helpers directly. Plan to recreate your key workflows, starting with the ones you use most.
