GraphQL API Development Company

GraphQL is a query language for APIs that lets clients request exactly the data they need. Unlike REST where each endpoint returns a fixed structure, GraphQL exposes a single endpoint and the client specifies which fields it wants. This eliminates over-fetching, under-fetching, and reduces the number of round trips. For projects with multiple data sources or diverse client applications (web, mobile, IoT), GraphQL provides a unified API layer that accelerates frontend development.

A ready-made platform from our catalogue - web app, admin panel and mobile apps - starts from $2,199 and launches in 6 working days. Custom GraphQL API work starts from $3,699, depending on the work. A custom federated GraphQL build typically runs $8,000-$25,000 and takes 2-8 weeks depending on scope: the number of sub-graphs, real-time subscription complexity, integration depth with existing systems, multi-region deployment and custom resolver logic beyond standard CRUD decide where it lands. Ongoing GraphQL work is available from $2,299/month for feature work and maintenance. Every project includes full source code ownership and 60 days of post-launch support. Every quote is written before payment, with no surprise invoices after kickoff.

Apollo Federation is a GraphQL architecture pattern where multiple microservices each own a sub-graph (a portion of the schema) and an Apollo Gateway composes them into a single unified schema. You need federation when your API spans multiple domains (e.g., users, orders, inventory) and different teams own different services. It allows each team to deploy independently while exposing one consistent GraphQL endpoint to clients.

A single GraphQL API with 3-5 data sources typically takes 14 days from discovery to deployment. Federated architectures with multiple sub-graphs range from 21 to 45 days depending on complexity. Miracuves delivers in that window because we start from our own tested building blocks for authentication, cursor pagination, file upload and subscriptions rather than writing them from scratch. If you need a whole product rather than an API, our 90+ ready-made platforms launch in 6 working days.

Yes, Miracuves specializes in REST-to-GraphQL migration. We analyze your existing REST endpoints, identify data shapes consumed by each client, and design a GraphQL schema that wraps or replaces the REST layer. The migration can be incremental - GraphQL and REST can coexist during the transition. We use schema stitching or Apollo Federation to compose your legacy REST endpoints as GraphQL sub-graphs, allowing a phased migration with zero downtime.

Miracuves builds GraphQL APIs on Node.js with TypeScript. Our standard stack includes Apollo Server or GraphQL Yoga for the runtime, Prisma ORM for database access, PostgreSQL as the primary database, Redis for caching and pub/sub, DataLoader for N+1 elimination, and graphql-ws for WebSocket subscriptions. We use GraphQL Codegen for type-safe resolvers, Docker for containerization, GitHub Actions for CI/CD, and Grafana + Prometheus for monitoring. For federated architectures, we use Apollo Router (or Apollo Gateway) with the Apollo Federation specification.

Yes, every Miracuves GraphQL project includes 60 days of post-launch support. This covers bug fixes, schema adjustments, performance tuning, and deployment issues. Enterprise plans include on-call support with defined SLAs. We also provide documentation for your GraphQL API, including schema documentation, resolver architecture, and deployment runbooks. Extended support and maintenance retainers are available.

We implement JWT-based authentication for most projects, with optional OAuth 2.0 / SSO integration for enterprise clients. Authorization is handled at the resolver level using a permission middleware pattern. We also implement query depth limiting, cost analysis, and rate limiting to prevent abusive queries. For federated architectures, the router validates the token and forwards it, or the verified claims, to each sub-graph in request headers; each sub-graph still enforces its own field-level rules. All implementations follow OWASP API Top 10 security guidelines.

Yes. Miracuves is based in Mumbai and delivers remotely to clients worldwide, including Denmark and the rest of Europe; we have no local office there. Projects run in English. Our hours, Mon-Sat 10:00-19:00 IST, overlap the European morning, and the first response comes in under 2 hours within them, so schema reviews and sprint demos are booked inside that overlap. An NDA is signed before you share any project detail.

Usually hours to a few days, not weeks. A field backed by a REST endpoint - written as a resolver or added declaratively with a directive - looks like any other field in the schema, so it shows up in the explorer, the generated types and the docs as soon as it is published. Teams already on GraphQL can use it the day it ships; teams new to GraphQL need a few days to set up the client, codegen and caching. We also document each field's latency and failure behavior, since a REST outage surfaces as a null field with an error rather than a failed page.

Yes, as a team rather than a lone contractor. On the ongoing development retainer, from $2,299/month, a Miracuves team is assigned to your graph for new features, schema changes and maintenance, with weekly demos, sprint planning and direct communication. The team scales up or down as needed, the retainer can be cancelled with 2 weeks notice, and all code remains 100% yours.
