Sole traders and micro businesses
You have an app built by HydraSoftware and you want it to simply work: up to date, secure, with small changes when you need them.
Development subscription
Your app looked after by a developer — for a fixed price.
Updates, fixes and new features within a monthly subscription. No booking every change and no invoices for hours you didn't know about.

Who it's for
For companies that have an app but no developer
Small companies growing a product
The app keeps changing: new fields, reports, integrations. Instead of quoting every job, you get a fixed amount of work every month.
An app without a caretaker
The previous developer or agency has left, but the app is still needed. We take over the project, tidy it up and keep maintaining it.
Plans
Three plans. Net prices, billed monthly.
You can switch plans from the next month. The subscription covers development work only — you pay for hosting and third-party services directly to the provider.

Project takeover
Taking over someone else's project is a separate one-off fee
Most of the work happens at the start: recovering the code, getting it running and understanding the project. That's why takeover is paid separately, so the subscription can stay low.
| Situation | One-off cost |
|---|---|
| An app built by HydraSoftware | PLN 0 |
| Someone else's project in a repository, in React or .NET, that can be run | PLN 1,500 – 3,000 |
| No repository or documentation, old code or another technology | Audit PLN 500 – 1,000 (deducted from the takeover), then a quote |
Taken-over projects have a minimum subscription period of 3 months.
Takeover includes
- Recovering the code and setting up a repository on your account
- Running it locally and on the server
- Automated deployments (CI/CD)
- A security review
- Project documentation
Development only
A clear split: code on our side, services on yours
The subscription covers development work only. You pay for infrastructure and third-party services directly to the provider — on your own account, with no markup.
In the subscription
- Code changes and new features
- Bug fixes
- Library and security updates
- Production releases
- Setting up third-party services
Paid to the provider
- Hosting, server, cloud, database
- Domains and certificates
- Software licences
- Paid services: payment gateways, e-mail, SMS, APIs, AI inside the app
The AI tools used in development are included in the subscription price.
How it works
From request to release
AI speeds up writing code, and a developer is responsible for what reaches production. Faster and cheaper, without the risk.
Request
A form or an e-mail. A few sentences are enough — we'll ask if anything is unclear.
Credit estimate
You know the task size before work starts. No surprises on the invoice.
Built with AI
AI prepares the change under the supervision of a developer, who reviews it before release.
Preview and release
You approve the change on a test version, then it goes to production.

Questions
Frequently asked questions
What if I don't send any requests in a month?
Your app is still looked after: updates, monitoring and backups run every month, and at the end of the month you get a summary of what was done. On credit plans, the unused pool rolls over to the next month.
Can I cancel?
Yes, with one month's notice. Taken-over projects have a minimum subscription period of 3 months.
Can I change plans?
Yes, from the next month — up or down.
Why is it cheaper than a software house?
A large part of the coding is done with AI, which shortens the work. A developer designs the solution, reviews every change and is responsible for what reaches production.
Who owns the code?
You do. The repository is on your account and the copyright to the code is transferred to you.
Which technologies do you work with?
React, TypeScript, .NET, PWA apps and Supabase. Projects in other technologies are accepted after an audit.
Are prices net?
Yes, 23% Polish VAT is added. You get an invoice every month.
Form
Choose a plan and tell us about your app
We reply within 1–2 business days with a plan suggestion and whether the project needs a takeover. Sending the form commits you to nothing.
