A studio for SaaS and open source, from Europe.

RelationSoftware builds its own products for developers, agencies and small software shops. Tools that run in Europe or on your own server. You get to keep them, even if you leave us one day.

Products - One principle behind every tool: you stay in control.

Every product exists because we needed it ourselves. They all run in Europe. Where possible, you can run them on your own server.

CamelMailer

Live

Transactional email, nothing else.

Receipts, password resets, magic links, alerts. The mail your product has to send. An open alternative to Postmark, Mailgun and Resend, as an EU cloud or self-hosted on your own server.

  • Open source (MIT)
  • Rust + PostgreSQL
  • EU cloud or self-hosted

Plan, publish and analyse posts without leaving your CRM. Every like and every comment becomes a lead, back in Pipedrive where your sales team already works.

How we work - Our own products, not client projects.

RelationSoftware is a small, independent studio. We build and run our own products, for the long haul and close to the people who use them.

  • Hosted in Europe. Our products run on servers in Europe. Data protection is not an add-on, it is the default.
  • Open where it counts. CamelMailer is open source under the MIT License. You can see what the code does, and you are not tied to us.
  • Self-hosting as a real option. Cloud convenience or full control on your own machine. Both are built in, not bolted on later.
  • For developers and agencies. We build for freelancers, agencies and small software shops. For people who use the same tools we do.

Built in the heart of Europe.
