Why people look beyond Sintra.

Helpers that suggest more than they do

Its own FAQ says each helper runs as a chatbot. Drafts are good; the doing is often still yours.

Credits on advanced actions

Plans include 250 credits a month; heavier work needs top-ups.

Hard to run a team on it

Approval levels are mentioned without detail, and per-person permissions are not described.

Where Sintra is hard to beat: price. With the model included, a solo founder gets twelve ready-made helpers for content, social and email for less than a lunch a week.

Questions people ask us.

What is the best Sintra alternative?

It depends on the job. For agents that do work across departments from one company brain, with your own EU server, Brainstack. For a flat price and unlimited teammates, Squad. The table above has the facts for each one.

Is there a Sintra alternative that includes the AI model?

Lindy and Dust include the model in their price. Brainstack and Squad run on the Claude, ChatGPT or Gemini plan you already have, so you pay the provider directly.

Which Sintra alternative keeps data in the EU?

Brainstack runs every customer on their own private server, in the US or Europe. Dust offers EU data residency. The others we checked don’t state a region on their sites.

Can I use my own ChatGPT or Claude plan?

With Brainstack and Squad, yes: they run on the plan you bring. With Brainstack you pay the provider directly, at their price, with no markup.

Does Brainstack have SOC 2?

Not yet. What we have: one private server per customer, per-person permissions, approvals before anything leaves, a record of what each agent did, and GDPR terms.
