One best practice, three engineering surfaces.
A single codebase discipline that reaches from browser extensions to a native binary and the API that keeps them in sync.
Manifest V3 extensions for every major browser, plus IDE and SDK plugins. Shared core, per-target packaging.
- MV3 service workers
- Cross-browser build
- Auto-update channels
Swift, Kotlin, and desktop shells with a shared logic layer. Notarized, signed, and delivered through the stores you already use.
- iOS + Android
- macOS · Windows · SmartTV
- Store submission
Typed SDKs, webhooks, and OAuth bridges that connect your clients to the services they depend on, with observability built in.
- Typed SDKs
- Webhooks & events
- OAuth 2.0 bridges
Extensions that survive every platform update.
We build browser extensions and native apps on shared testable core, then package per target. When a store changes its policy or a manifest version deprecates, we handle the migration while you keep shipping.

macOS Notarized
Service workers, declarative NetRequest, and scoped permissions done right the first time.
One core module compiled and packaged for Chromium, Gecko, and WebKit.
Percentage rollouts, kill-switches, and instant rollback across channels.
Least-privilege permissions and transparent data flows that pass store review.
Native where it counts.
Shared where it pays.
Platform-true interfaces backed by a portable logic core, so a fix lands everywhere at once and your team ships from one repository.

The connective tissue between your surfaces.
An advanced SDK, webhooks, and OAuth bridges keep extensions, native apps, and your backend speaking the same language. Observability and rate-limiting are wired in from day one.

Traces & metrics
Built for teams that treat client software as product.
Browser extensions and companion desktop apps that automate repetitive work without leaving the browser.
Content filters, password tooling, and consent managers built to pass the strictest store reviews.
Price intelligence, checkout assistants, and price comparison native apps.
IDE plugins, CLI companions, and API dashboards that meet developers where they already work.
A small studio with a long changelog.
Kavento Studio LTD is a UK based engineering studio focused on the building browser extensions, native apps, and the integrations between them. We favor small teams, tight feedback loops, and maintenance we don't walk away from.
We treat store policy, platform deprecations, and security review as part of the build, not surprises after launch.
