Web apps and complex sites that do real work, not just look good. Designed and shipped for law firms, not generic templates with law firms swapped in.
Most law firms are operating on sites or software stacks built three to five years ago for a different version of the buyer. New-matter intake runs on phone calls and email, so after-hours inquiries go unanswered and signed-case revenue leaks at the door. The infrastructure decisions that compound are the ones made with the operator in the room, not the ones made in a vacuum.
Inparlor's Web Application Development engagement for law firms reflects that. We build web applications: customer-facing apps, internal dashboards, data-heavy portals, and complex content sites that go well past a brochure. The deliverables below are scoped against the unit economics, signed pi case value (avg) of $25,000-$80,000.
Where most agencies treat law firms as another vertical to learn on, we treat the vertical as the starting point. Case files, deadlines, and client communication live across disconnected tools, so status updates require digging through inboxes. We will tell you on the first call which of those constraints is binding and which is solvable inside the engagement.

Even brand-new sites have legacy URLs to honor, orphaned PDFs, archived blog posts, vendor microsites. Missing a 301 is how organic traffic dies on launch day, so the redirect map is week-one work, not a launch-day checklist.
Largest Contentful Paint under 2 seconds on a 4G mobile connection. Cumulative Layout Shift under 0.05. We hit it on every preview deploy, not just at launch, and we keep hitting it for 90 days after.
We default to Sanity, Contentful, or MDX-on-GitHub depending on team size. Editors get a workflow they will actually use, preview environments, scheduled publishes, and roll-back if anything breaks.
GA4 events tied to revenue, not pageviews. Meta CAPI on day one for any site that will run paid traffic. The dashboard tells the truth before the brand approves the design.
