For 17+ years we have partnered with governments, agencies, and public institutions to ship secure, accessible apps without the usual contractor friction, whether the goal is to modernize, scale, or replace an existing system or to launch something new. For public-sector and regulated work, we offer a fully American team, with leadership, product and project management, senior development, design, QA, and marketing all held by our US staff. For budget-sensitive, non-regulated projects, a cost-effective US-plus-offshore blend remains available, drawing on our in-house design team in Brazil and our in-house development, QA, and project-management teams in Pakistan and India. Either way, everyone is in-house and assigned directly to your project, never subcontractors or middlemen, at the same quality, timelines, and customer experience. Our work spans HIPAA, GDPR, and SOC 2 requirements. You get fixed monthly budgets, transparent pricing, precise timelines, and direct access to the real senior team rather than a lone salesperson concealing offshore developers or a faceless overseas shop with no time-zone overlap. Daily Slack, weekly Zoom for design and bi-weekly Zoom for development, and 24/7 visibility in Figma, GitHub, Jira, and Confluence mean public stakeholders always know where things stand and who is accountable, and you own all your code and IP.

Across 500+ launches, products we have built have reached more than 1 billion users with 92% client retention, and we have shipped real civic platforms firsthand. Organizations that have trusted Chop Dawg include NASA, the U.S. Navy, the White House, and the City of Philadelphia, alongside the documented public-sector case studies below. Our City of Peachtree Corners build is a smart-city app for a community of 42,000-plus residents that unified city services, events, and community reporting and drew thousands of downloads in its first month. We also developed the City of Springboro, Ohio platform for local-government tax filing, Accurate Voting Services for election management, and JusticePath, which brings digital court connectivity to the people who need it. That is smart cities, tax administration, elections, and the courts, the core categories of public-sector work, each built to the accessibility and compliance standards agencies require. Agencies value that we deliver on time and on budget with no surprises, then back every launch with complimentary post-launch bug-fixing and monitoring through our support services.

Frequently Asked Questions

What is Section 508 and why does it matter for government apps?

Section 508 is a federal law requiring electronic and information technology to be accessible to people with disabilities, and it adopts WCAG success criteria in practice. Government apps must meet it, so build accessibility in from the start. Several firms above, including Coforma and Ad Hoc, treat accessibility as core to delivery.

How does government procurement for app development work?

Agencies typically procure through competitive solicitations, set-aside contracts, or established vehicles like GSA schedules, with requirements for security, accessibility, and past performance. Small-business and veteran-owned set-asides are common. Work with a partner who understands documentation, compliance, and the cadence agencies expect throughout a contract.

What compliance standards apply to government apps?

Beyond Section 508 accessibility, agencies often require FedRAMP-authorized hosting for cloud services, plus controls aligned to frameworks like FISMA and NIST. Healthcare-related projects may add HIPAA. Confirm the exact requirements for your agency early, since they shape architecture, hosting, and cost from day one.

How much does a government app cost?

Costs vary widely with security, accessibility, and integration needs, but complex public-sector apps commonly run $150,000 to $400,000 or more, while smaller tools may fall in the $50,000 to $150,000 range. AI-assisted development has trimmed build cost and time meaningfully since 2023, though security reviews and compliance work remain the larger drivers in government projects. A detailed discovery phase yields the most accurate estimate. Our cost guide outlines the drivers.

How long does a government app project take?

Government app projects often run six to twelve months or more, since security reviews, accessibility testing, and stakeholder approvals add time. Phasing the rollout helps agencies deliver value sooner while larger features mature. Clear documentation and regular check-ins keep timelines and compliance on track throughout.
