Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.

Rule summary

  • Posts em português: Somente posts em português, para inglês é possível utilizar outras comunidades de microsaas focadas no público global.
  • Somente posts sobre MicroSaaS: Não aceitamos assuntos fora desse tema
  • Seja respeitoso: Sem intrigas, brigas, xingamentos, desrespeito
  • Seja direto e faça o mínimo de pesquisa antes: Não será aceito perguntas muito amplas, tipo: "como posso criar um microssas?". É esperado que você traga perguntas mais diretas e que faça uma pesquisa prévia para termos discussões mais focadas.
  • Proibido MicroSaaS "feito em 5 minutos" e ilegais: Não poste MicroSaaS criados sem esforço real. Se você não validou a ideia, não tem essa dor, não conhece ninguém que tem, não conversou com nenhum potencial usuário e só jogou um prompt genérico numa IA pra gerar algo descartável, seu post será removido. MicroSaaS ilegais tbm serão removidos.

Works well

  • A build log in Portuguese describing one concrete problem you solved in your microsaas this month.
  • A narrow question about pricing or distribution for a bootstrapped product, asked after you explain what you already tried.
  • A validation story that names who you talked to, what pain you found, and what you changed as a result.
  • A technical or tooling question specific to running a small software as a service, like stacks or automation choices.
  • A lesson learned post where any mention of your own product is framed around what other builders can take from it.

Avoid

  • Posting in English, since “Posts em português” sends non-Portuguese posts out to global communities instead.
  • Asking something like how to create a microsaas from zero, which “Seja direto e faça o mínimo de pesquisa antes” calls out as too broad.
  • Dropping a link with no context, because off-topic or low-effort posts get removed even if promotion itself is not spelled out in the rules.
  • Announcing an AI-generated wrapper you built in an afternoon, which “Proibido MicroSaaS “feito em 5 minutos” e ilegais” removes outright.
  • Arguing with commenters or moderators, since “Seja respeitoso” bans feuds, insults, and disrespect.
  • Posting about a general business or marketing topic with no software-as-a-service angle, which “Somente posts sobre MicroSaaS” rejects.

What r/MicroSaaSBR Is For

This is a Brazilian community for people who build micro SaaS. The description says it exists to discuss everything about micro SaaS, from finding ideas to creating, developing, and maintaining software as a service without outside investment. The people here are bootstrappers, solo founders, and small teams. Everything runs in Portuguese, and the rules say English posts belong in other global microsaas communities instead. So this is a room of Brazilian makers talking shop with each other, not a global audience.

Rules That Matter Before Posting

Four rules decide whether a marketing-adjacent post survives here. “Posts em português” means your post must be written in Portuguese, full stop. “Somente posts sobre MicroSaaS” means your post has to connect to building or running a small software as a service product. “Seja direto e faça o mínimo de pesquisa antes” means vague, broad questions get removed, so do your homework first. “Proibido MicroSaaS “feito em 5 minutos” e ilegais” is the strictest one for founders, because it removes products made without real effort, without validation, without talking to any potential user, or from a single generic AI prompt. “Seja respeitoso” matters too, since drama and insults are not tolerated.

What To Post

Write in Portuguese, first and always. A good post here is a specific story or a specific question about building your micro SaaS. Share what you validated, who you talked to, and what you learned, because that is exactly what the low effort rule rewards. If you are promoting anything, wrap it in a real lesson, like how you found your first users or what your pricing experiment taught you, and keep it on topic for bootstrapped software. Ask narrow questions you could not answer with a quick search, like a comparison between two pricing models or a specific technical choice. Show the real work behind your product, not a polished announcement.

What To Avoid

The fastest way to get removed is posting in English, because rule one sends non-Portuguese posts away. The second fastest is a lazy launch post. If you have not validated the idea, do not feel the pain yourself, do not know anyone who has it, and have not talked to a single potential user, your post is gone. A generic AI prompt that spits out a disposable product is called out by name in the rules. Broad questions like how do I create a microsaas are also removed, because the community wants focused discussions after you have done some research. Anything outside the micro SaaS topic is out, and so is anything illegal. Being disrespectful, starting fights, or insulting people will get you removed too.

Common questions about r/MicroSaaSBR

Can I post in English if my Portuguese is weak?

No. The rule “Posts em português” is explicit, and it points English speakers to other microsaas communities for a global audience.

Is self-promotion allowed?

The rules do not state a promotion policy either way, so treat any promotional post as risky and lead with genuine substance in Portuguese instead.

Can I share a project I built with AI help?

Only if it involved real effort and validation. The rules remove projects made with a generic AI prompt and no user conversations, so show the work behind it.

Can I ask for feedback on an idea?

Yes, if it is specific and you did some research first. The rules reject very broad questions, not questions in general.

What topics count as on topic?

The description covers finding ideas, building, developing, and maintaining bootstrapped software as a service, so pricing and validation fit as long as your post is focused.
