Cybersecurity + automation, built in

Secured, automated, and running on AgentOS

Every custom system we build is secured and automated by default. Every agent runs on XDQ AgentOS, guardrails, human gates and an audit trail included.

FIND · FIX · VERIFY
Secure by default
We test and close the attack surface, web, API, cloud and the AI/agent layer, before you launch, then re-test to verify.
CYBER BRAIN
AI security analysis on watch
An AI security brain reviews new exposure as your product changes, prompt injection, tool abuse, leaked secrets, and flags what moved.
AUTOMATED
Guardrails in the pipeline
Secret scanning, policy checks and guardrails run automatically on every deploy. Human-gated, you approve each change.
FAQ

Questions we get about custom software development

How long does a custom build take?

Most scoped builds run 4-10 weeks. We quote a fixed price and a date after one scoping call.

Who owns the code?

You do, on payment. The repo, infrastructure and deploy scripts are yours from the first week.

Can you take over an existing codebase?

Yes. We start with a security and architecture pass, then quote the change you need rather than a rewrite.

Custom Software Development Services: More Questions Answered

How much does custom software development cost?

Custom software development with XDQ Labs is priced as a custom quotation from our sales experts after a brief. Small internal tools usually fall in the USD 1,000 to 5,000 band, portals and workflow systems in the 5,000 to 20,000 band, multi-module operations platforms between 20,000 and 50,000, and large programmes in the 50,000 to 200,000 band. Each quote lists deliverables, milestones and a delivery date, so the cost does not grow during the build.

When should a business replace spreadsheets with custom software?

Replace spreadsheets when several people edit the same data, errors are costing money, or reporting takes hours each week. Custom software adds roles and permissions, validation, an audit history and dashboards that update on their own. We usually start by mapping how the spreadsheets are used today, then rebuild the core workflow in four to eight weeks and migrate the historical data before switching over.

Can you migrate an application off Bubble or legacy PHP?

Yes, we migrate applications from Bubble, legacy PHP and similar platforms to a maintainable stack based on TypeScript, Node.js and PostgreSQL. We begin with an audit of features, data and integrations, then rebuild in stages so users keep working throughout. Data migration is rehearsed before the final switch. A typical migration takes 6 to 12 weeks, depending on the size of the existing application and its integrations.

What is the difference between custom software and off-the-shelf software?

Off-the-shelf software fits a common process quickly, while custom software fits your exact process and becomes an asset you own. Custom software makes sense when your workflow is a competitive advantage, when licence costs grow with headcount, or when several tools need to act as one system. Often the best result is a mix: keep packaged tools where they work and build custom software around the gaps.

Do you provide support and maintenance after launch?

Yes, after launch you can choose a monthly retainer or a full handover to your own team. A retainer covers bug fixes, small features, dependency updates, monitoring and a regular security pass, with response times agreed upfront. A handover includes the repository, infrastructure access, deploy scripts and documentation. Many clients keep a retainer for the first three to six months while usage settles.
