Chrome & Browser Extension Development
Manifest V3 extensions that survive store review and Chrome's next update.
Browser extensions for productivity, internal tooling, and product companion experiences — built to Manifest V3, with permissions kept minimal so store review is straightforward.
What the engagement includes
- Manifest V3 from the start — Service workers and declarative rules, not a V2 port waiting to break.
- Minimal permission scope — Only the permissions the feature needs, which speeds review and user trust.
- Cross-browser builds — One codebase targeting Chrome, Edge, and Firefox where feasible.
- Secure messaging — Hardened content-script and background communication.
- Store submission — Listing assets, privacy disclosures, and review responses handled.
- Enterprise deployment — Managed policy installation for organisation-wide rollout.

How we approach this work
Every chrome extension development engagement runs on the same delivery model — the specifics below change, the discipline does not.

Process
How a project runs
- 01
Requirements
Workshops with your stakeholders to establish scope, constraints, and success criteria.
- 02
Research
User, competitor, and technical research to challenge assumptions before they become code.
- 03
Architecture
System design, integration mapping, and a written record of the trade-offs we chose.
- 04
Design
Flows, screens, and every non-happy state, delivered as a working component system.
- 05
Build
Two-week increments, each ending in something demo-able on a real environment.
- 06
Test
Automated regression plus exploratory passes under poor-network and low-end device conditions.
- 07
Launch
Staged rollout, store submission, monitoring, and a rollback plan agreed in advance.
- 08
Measure
Instrumentation reviewed against the success criteria set in step one.
- 09
Support
Maintenance retainer covering OS upgrades, dependency patching, and SLA-backed fixes.
FAQ
Chrome Extension Development questions
How do we start, and what does it cost?
With a Product Requirement Analysis for ₹3,500: a call with the people who will build it, your requirements worked through, and a written quotation and timeline. Pay on our Razorpay page, then pick a time at elevatebox.in/book.
How do you price engagements?
Fixed-price for well-defined scopes, and time-and-materials for evolving products. We recommend fixed-price discovery first so the build estimate is based on evidence rather than assumption.
Who owns the code and infrastructure?
You do, throughout. Repository, cloud accounts, and deployment credentials are in your name from the first commit, not transferred at the end.
How long does a typical project take?
A focused MVP is usually eight to sixteen weeks. Platform work and multi-app products run longer. We give a range with a confidence level, and narrow it as unknowns resolve.
Can you work with our existing team?
Yes. We embed in your repositories, stand-ups, and review process, or run a parallel workstream with defined interfaces — whichever fits how you already work.
What happens after launch?
A maintenance retainer covering OS and dependency upgrades, monitoring, and SLA-backed fixes. You can also take it entirely in-house — the documentation and handover support that with are included.
Do you sign NDAs and custom contracts?
Yes. We work under client MSAs and NDAs routinely, including UK, EU, UAE, and US terms, and we can complete security questionnaires as part of onboarding.
Which time zones do you cover?
We commit to a daily overlap window agreed before the contract starts. UAE and Europe get near-full overlap; US clients get a committed morning or evening window.
Will you tell us if we should not build something?
Yes, and we do. If a simpler tool or no build at all serves you better, we say so during discovery rather than after invoicing the build.
