Chrome Extension Development, Publishing & Promotion

Chrome has over 3 billion users. A browser extension puts your product, brand or internal tool one click away from them, every day, on every site they visit. RAAGIT designs, publishes and promotes Chrome extensions from start to finish. Bring us an idea, an internal tool, or an extension that keeps getting rejected, and we take it from where it is to where it needs to be.

We publish your Chrome extension

This is the part most teams underestimate. The code is rarely what blocks a launch. The Chrome Web Store review is. So are the privacy disclosures, the permission justifications, the screenshots that have to persuade someone to install, and the developer account dance with Google. We handle all of it. Whether you wrote the extension yourself or we built it together, we get it live.

What we publish:

• Commercial extensions for SaaS products, agencies and consumer brands, as a public Chrome Web Store listing optimised to be found and installed
• Internal extensions for your employees, distributed privately through Chrome Enterprise or the Google Admin Console. No public listing, no third-party install warnings
• White-label and unlisted extensions, published but invisible to the public and open only to the clients or partners you share the link with
• Cross-browser releases, so the same extension also goes live on Edge Add-ons and Firefox AMO when the audience justifies it
• Stuck or rejected extensions. We audit what Google flagged, fix the manifest, permissions, privacy policy and listing copy, then resubmit. Most rejections come down to fixable issues we’ve seen many times

What “we publish” includes in practice:

• Developer account setup, or use of ours if you’d rather skip the $5 fee and the waiting period
• A Manifest V3 compliance review before submission, so there are no surprise rejections
• A privacy policy and data-handling disclosures that pass Google’s stricter 2024+ review
• Listing copy, category selection, screenshots and promotional tiles written and designed to turn browsers into installs
• Direct communication with Google’s review team on your behalf when something needs clarifying
• Version updates, rollbacks and staged rollouts after launch

Chrome extension development

We build extensions from scratch for clients who don’t have one yet. Modern stack, clean code, and only the permissions the extension needs, which also makes review faster.

What we build:

• Productivity tools: internal extensions that plug into your CRM, ticketing system, intranet or custom backend
• Brand extensions: branded new-tab pages, news feeds, quick-link launchers, loyalty programmes
• Marketing extensions: coupon finders, cashback and affiliate trackers, price comparison
• SaaS companion tools: sidebar panels, page overlays and content scrapers that carry your B2B product into the browser
• AI assistants: GPT-integrated summarisers, writing aids, in-context tools
• E-commerce helpers: wishlists, product finders, drop alerts
• Security and compliance: policy enforcement, content filtering, DLP tooling for enterprises

If you have a backend, we wire the extension to it. If you don’t, we build that too, with the same team.

Promotion and Chrome Web Store ASO

A published extension nobody finds is a wasted budget. Chrome Web Store optimisation is real and underused. We treat it the way ASO teams treat App Store and Play Store listings.

• Listing optimisation: keyword research for the Chrome Web Store, title and short-description tuning, descriptions and screenshots written to convert
• Category and competitor positioning, meaning the slot where you have a chance to rank
• Review and rating management: early reviewer outreach, response templates, and dealing with negative reviews before they hurt you
• Launch placements on Product Hunt, Hacker News, niche subreddits and newsletter sponsorships in the categories where extension users spend their time
• Paid acquisition when it makes sense: Google Ads for branded queries, Reddit promoted posts, YouTube reviews in the relevant niche
• Cross-promotion between your own extensions, or with our portfolio where the audiences overlap

For companies and internal use

You don’t need a public Chrome Web Store listing to deploy an extension to your team.

• Chrome Enterprise deployment: push the extension to specific Google Workspace users, organisational units or device groups via the Admin Console
• Forced install, so the extension installs silently on every managed Chrome browser in your organisation
• Locked configuration: preset values, hidden options, organisation-wide policies that users cannot override
• SSO integration with Google Workspace, Okta and Azure AD, with no separate logins
• Audit logging, so you can see who used what, and when, across the company
• GDPR-aligned data handling: minimal collection, clear retention, and defensible if anyone asks

This route suits internal CRM helpers, support-team tools, compliance extensions and anything you only want your own people to have.

How we work

1. Discovery. What the extension needs to do, which pages it touches, which APIs it talks to, who it’s for.
2. Architecture. Manifest V3, the smallest workable permission set, storage and sync strategy.
3. Design. Popup, side panel, options page and any injected UI, designed to feel native to Chrome.
4. Development in TypeScript, with code review and automated tests.
5. Submission and publication through the Web Store or the Admin Console. We handle every step.
6. Promotion, if you want growth as well as a launch.
7. Maintenance. Chrome’s APIs change. We track the deprecations and ship updates before they break you.

Technical capabilities

• Manifest V3, the current service-worker-based standard and the only thing Google now accepts
• Content scripts that read and rewrite the page DOM in real time, with care
• Background service workers: persistent logic that doesn’t drain the user’s battery
• Chrome Storage API, so settings follow the user across devices
• OAuth and API integrations with any backend or third-party service, including Google Workspace APIs
• TypeScript with Vite or Webpack: modern build tooling and code the next developer can read
• Automated testing with Playwright and Jest, configured for extension contexts

Why RAAGIT

• A full-stack team. We build the extension and the API it talks to, so you have one vendor for the whole loop
• Publishing experience on both the public Chrome Web Store and Chrome Enterprise. Most agencies know only one route
• We’ve taken extensions that other teams couldn’t get past Google review and got them approved
• We don’t request permissions you don’t need: clean manifests, faster reviews, better user trust
• Post-launch support as Chrome’s extension platform changes (and it changes often)

“A Chrome extension is the rare touchpoint that lives on every page your customer visits. Built and launched well, it builds loyalty. Built and launched badly, it gets uninstalled in under a minute.”
