Why LocalHost Digital

Measurable results, not vague promises

01

Modern, maintainable tech stacks

We build on Next.js, TypeScript, Node.js, and PostgreSQL — proven technologies with large talent pools that ensure your app can be maintained and extended long-term.

02

Canadian data residency

All applications are deployed on Canadian cloud regions (AWS ca-central-1, Azure Canada Central) so your customer data never leaves Canada — a PIPEDA requirement.

03

Security by design

Authentication (OAuth2, MFA), input validation, SQL injection prevention, HTTPS enforcement, and regular security audits are built into every application from the ground up.

04

Agile delivery with 2-week sprints

You see working software every two weeks — not a big reveal at the end. This reduces risk, allows course correction, and keeps projects on budget.

05

Bilingual-first architecture

Every application we build uses next-intl or i18next from day one — not bolted on later. Adding French (or other languages) never requires a rebuild.

06

Post-launch ownership transfer

You receive full source code, documentation, and infrastructure access. We provide knowledge transfer training for your internal team.

Frequently asked questions

How long does a custom application take to build?+
A focused internal tool or customer portal typically takes 6–10 weeks. A full SaaS product or mobile app takes 3–6 months depending on complexity. We provide a detailed estimate after our discovery workshop.
How much does custom application development cost?+
Custom applications start at $8,000 CAD for a focused internal tool and range to $50,000+ for complex SaaS platforms. We offer fixed-scope quotes for well-defined projects and time-and-materials for evolving requirements.
What technologies do you use?+
Our primary stack is Next.js (TypeScript), Node.js, PostgreSQL, and React Native for mobile. We also work with Laravel/PHP, Python/Django, and Vue.js. We always recommend the most maintainable technology for your team's long-term context.
Will you host and maintain the application?+
Yes. We offer managed hosting on AWS Canada or Azure Canada, with uptime monitoring, automated backups, security patching, and monthly maintenance retainers starting at $499 CAD/month.
Who owns the source code?+
You do. 100%. On completion, all source code, assets, database schemas, and infrastructure configuration are transferred to you. We never retain proprietary ownership of work we build for clients.
Can you integrate with our existing systems?+
Yes. We integrate with QuickBooks, Salesforce, HubSpot, Shopify, Microsoft 365, Google Workspace, and virtually any system with an API. We also build custom integrations for legacy systems without public APIs.
