Web development for Bengaluru startups and SaaS.
Bengaluru knows good engineering when it sees it, and knows the cost of bad. RoseLeap builds production-grade web applications and websites on a modern stack: Next.js, React, TypeScript, Postgres, AI. Senior-only, no junior pyramid, code you own from day one. Built for founders and product teams who would otherwise have to hire in-house.
What a serious studio actually changes.
The stack you would hire for
Next.js 16, React 19, TypeScript, Postgres, edge hosting. The same stack a good Bengaluru CTO would choose, built to scale and easy for your future in-house team to take over.
You own everything
Code in your Git, hosting in your accounts, secrets in your vault. We hand over the keys. No proprietary CMS, no lock-in, no hostage situations at renewal.
AI woven in, not bolted on
Claude-powered assistants, RAG search, automation, integrated into your product with cost engineering (prompt caching, model routing) so the inference bill stays sane.
Senior-only, fractional-CTO grade
No juniors learning on your dime. You get senior engineering judgement on architecture, scale and security, the kind early-stage teams cannot yet afford full-time.
From marketing sites to custom web apps.
SaaS & web apps
Multi-tenant platforms, dashboards, portals with auth and billing.
MVP development
Ship a credible MVP fast, on a stack that survives growth.
AI features
Assistants, semantic search, automation, production-grade.
APIs & backends
REST/tRPC APIs, Postgres, background jobs, integrations.
Marketing sites
Fast, distinctive product and company sites.
Rescue & takeover
Stabilise and ship a stalled or inherited codebase.
Working with RoseLeap in Bengaluru.
How much does web app development cost in Bengaluru?
+
A focused MVP web app in Bengaluru typically starts at ₹4-6 lakh for auth, a database and core flows. Larger SaaS platforms with multi-tenancy, billing, integrations or AI scale into ₹10-30 lakh. We work in fixed-scope phases with a shippable result at the end of each, so you are never committing the full budget on faith.
Do you work with early-stage startups or only funded companies?
+
Both. For pre-seed and bootstrapped founders we scope tight MVPs that prove the idea without burning the runway. For funded teams we act as a senior engineering partner, building the product while you hire your in-house team, then handing over cleanly. We are honest about when you should hire in-house instead of using us.
Can you integrate AI / Claude into our product?
+
Yes, it is one of our core strengths. We build assistants, document Q&A, semantic search and automation using the Claude API and others, with grounding (RAG with citations), guardrails and an offline eval suite. We engineer for low cost-per-call from day one using prompt caching and model routing, so AI features are margin-positive rather than a money pit.
Will we own the code, or are we locked in?
+
You own all of it, code in your GitHub, infrastructure in your cloud accounts. We build on open, standard tools (Next.js, Postgres, Vercel/fly.io) precisely so any competent engineer or your future in-house team can take over without us. No proprietary platform, no lock-in.
Are you a Bengaluru-based company?
+
We are based in Chandigarh and work with Bengaluru teams remotely, which is how most product engineering happens anyway. You get senior engineering at sensible rates without Bengaluru salary or office overhead priced into the work. For deeper engagements we do periodic on-site sessions.
