Own Your Software

How We Get You There

#01 Choose Your Software

Pick a software from our list, like a CRM, ERP or a Booking System. You buy the actual code from us one time, and you own it forever. No monthly "per-user" fees. Each one comes with all core-features.

< Clean, well documented and tested code built on modern Symfony 8 core. >

#02 Get the Full Source Code

We transfer the complete application to you — directly to your private GitHub repository, or as a downloadable source-code package. No locked platform, no proprietary builder. The code is yours.

< Full application source transferred to your private GitHub repository. Backend, frontend, database migrations, tests and deployment config included. >

#03 We Launch it for You

You don't need to be a computer expert or hire a developer to start. We help you setup a server, upload the software, connect your web address (domain), and make sure everything is running perfectly.

< Our agent helps setup a server (Google Cloud/DigitalOcean) and deploys it. It handles SSL, Database, spins up Docker containers and CI pipeline. >

#04 Start Using It

Log in on day one and start working. Your team uses the software like any SaaS product — but you own every byte of it. We provide onboarding documentation for every template.

< Production-ready core: Backend (permissions, logs, integrations, security), APIs, admin & frontend. Your team can use it immediately. >

After launch

Once it’s up and running, keep developing it without a tech team

We’ll provide full documentation so you can run the product locally and make changes without a tech team — AI agents are your tech team now. With just basic tech knowledge, you can ship updates yourself. And if something breaks, we’ll connect you with experts who know your stack.

01

Tell AI what you want

Open your SolidSource project in Cursor and describe the change in plain English.

02

See it before anyone else does

Run your software locally and test the change on your own computer. Nothing touches your live product until you’re happy with it.

03

Put it live

Happy with the change? Ask your AI agent to ship it. SolidSource deploys it to your server and verifies that everything is running correctly.

SolidSource Guard

Optional · From €39/mo

Own your software.
Don’t run it alone.

Guard keeps watch after launch. It monitors your server, handles routine maintenance, checks for security problems, and gives you a human to call if something goes wrong.

Time to value

Save months of development and testing time

Compare the effort of building from scratch with starting on a SolidSource foundation — shipping, security, and ownership included.

Starting from Scratch

6-12 months

Typical time before a system is stable enough to actually use.

  • Building authentication, users, permissions and security
  • Discovering essential features only after you start using it
  • Testing and debugging hundreds of edge cases
  • Figuring out servers, deployment, backups and infrastructure
  • AI agents gradually creating inconsistent architecture
  • Months spent rebuilding foundations instead of your unique features

Built on SolidSource

From day one

Start with a working system — then customize and extend it.

  • Production-ready software tested in real-world use
  • Authentication, permissions and core features already built
  • Clean architecture designed for AI-assisted development
  • Deployment, hosting and CI patterns already in place
  • Complete source code and infrastructure owned by you
  • Spend your time making the software fit your business

Why Smart Companies Are Leaving SaaS

SaaS costs compound.

Subscription spend adds up year after year—you pay repeatedly and still own nothing. With SolidSource you invest in software that stays yours, and always free.

Your data stays where it belongs.

Customer data, business logic, and trade secrets live on your infrastructure, not a vendor’s. Full control for compliance and risk.

Your data won’t train someone else’s AI.

Many platforms use customer data to improve their models. Owned software keeps your data out of third-party training pipelines.

No more feature hostage situations.

No waiting on a roadmap, no paying for a top tier to unlock one capability. You decide what ships and when. And simply ask an AI agent to build it at almost zero cost.

Why Start With a SolidSource Foundation

Skip the "Blank Page" Phase.

When you start from scratch, you don’t just build features — you discover everything you forgot. Auth, roles, edge cases, deployments… it adds up to months of debugging and rework. We’ve already done that part. You start with a complete, working system.

MCP Ready: Bring Your Own Brain.

Model-agnostic and MCP-native: plug in GPT, Claude, or a private local LLM. Your data stays in your fortress—you pick the brain.

Vibe-coding without a foundation becomes debt.

Starting from scratch with loose structure feels fast until shortcuts pile up. Code turns messy, hard to change, and brittle. A deliberate foundation keeps architecture clear so velocity lasts.

Deploy, monitor, help—your way.

We help you deploy and observe production systems and you choose how involved we stay: hands-off ownership, paired delivery, or ongoing ops support.

SME With SaaS

~€800–€2,000/month

Example range based on common small–mid business tool stacks in a company with 30-100 employees

Own It

~€80/month

Expected estimated cost for running the software on your own cloud server, Cloudflare security, plus SolidSource Guard and support.

What if I break the software while trying to change it?

The Reality. You are not coding on a blank page; you are building on a professional chassis that keeps capable AI agents within safe lanes. You can test every change locally first, while built-in testing routines automatically scan for errors so experimental features do not break the system. Automated checks act as a last line of defense before anything reaches your live server.

What ifI need a feature that does not exist in the base product?

Yes that's the point. The stack is yours to extend: new modules, integrations, and workflows can be added on top of the Symfony foundation without fighting the core product. You own the repository, so you are never stuck waiting on a vendor roadmap for something critical to your business.

Do I need to be a developer to use the software?

Not at all! Modern AI assistants can draft and explain changes step by step on a codebase that is already structured and documented for you. You still approve what ships, and guardrails plus review flows keep production safe—so the team focuses on business decisions, not memorizing syntax.

Is my customer data actually safe on a server I control?

The Reality. Your system is built so application logic, database, and files stay clearly separated. Data lives in managed infrastructure from providers like Google Cloud or DigitalOcean, with maintenance, patches, and backups handled for you. You retain full ownership of the account and everything inside it.

How future-proof is this investment?

The Reality. You own the source and the infrastructure, so the system keeps running regardless of our roadmap. It is built on Symfony so it stays compatible with evolving tools and security practices. Any qualified developer can maintain it—you are not trapped in proprietary lock-in.

What if I want to host or maintain everything myself later?

The Reality. The repository and deployment blueprint are yours. You can move providers, adjust hosting, or bring in another team whenever you want—we are not the gatekeeper to your runtime or your data.
