Web app development services for apps that survive their second year

Web app development services include scoping, the data model, the front end and back end, integrations with the systems you run, hosting and monitoring, and maintenance after launch. Hashlogics delivers all of it with one senior team, for enterprises and startups.

Build a progressive web app when users arrive by link, you want one codebase and releases without store review, and browser features are enough. Build a store app when you need deep device access or App Store discovery. ZyloBase shipped as an offline-capable PWA for field reps.

Yes, one team builds both, from the React, Next.js or Vue front end to the Node.js, FastAPI or Laravel back end and the PostgreSQL database. That way the API and the screens are designed together and nobody hands a bug across a contract line.

Both, chosen by what you already run and who will maintain it. We build front ends in React, Next.js and Vue, and back ends in Node.js, FastAPI and Laravel; TankAware runs on Laravel and AWS, for example.

A web application is software people log into and do work in, and a website is something they read. Logins, records, permissions and workflows put you on the application side. That distinction sets your budget, because an application needs a data model, roles and a plan for the day the data grows.

Every build starts with a fixed-fee Blueprint: an engineer reads your real systems and writes the plan, with a fixed price for each milestone rather than a guess. The fee is credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it. We read the codebase, find what is load-bearing, and tell you what is worth keeping against what should be rewritten. The scoping call before it is free.

Rarely. Most slowdowns come from a handful of queries and a missing index, and they get worse quietly until one page times out. We measure before proposing anything, because a rewrite sold without a measurement is a vendor protecting its own margin.

Separation is enforced in the database, not in the interface. Trading CoPilot and ExtraaJe both use Postgres row-level security through Supabase. A query that forgets a filter returns nothing, not someone else's records. Multi-tenant products get this decided in the first week.

Yes, all of it, and it lives in your accounts from the first deploy rather than being handed over at the end. That includes the repository, the infrastructure and the keys. Anything less means your business depends on a vendor answering an email. The first 2 months of support and maintenance are free, with every build.

Yes, through their APIs, and that is nearly always cheaper than replacing them. Across our builds that has meant Stripe, QuickBooks, Twilio, HubSpot, Google Calendar and a government right-to-work service. We only propose replacing a system when keeping it costs more than it saves.

Cost is driven by how many user roles exist, how many outside systems the app touches, and whether it must satisfy an auditor. Naming a range before seeing the workflow is guessing, and the guess protects nobody. The scoping call is free, and the fixed-fee Blueprint, credited in full against the build, fixes the price before the build starts.

Both, and they buy different things. A startup wants one workflow live and evidence that users return, so we ship narrow and instrument it. An enterprise wants audit trails, role separation and integration with what already runs, which is what TrialTriage needed across four user types. The engineering standard does not change between them.
