Extinde
Extinde is an AI browser-extension builder: describe an idea in plain English and it generates production-ready Manifest V3 code, icons and manifest, exportable to Chrome, Firefox, Edge and Safari from a single codebase, with no coding required.
What is Extinde?
Extinde is a web-based AI builder for browser extensions. You describe what you want in plain English, and it returns production-ready extension code, icons and a Manifest V3 manifest, presented as ready for Chrome Web Store review. A single codebase exports to Chrome, Firefox, Edge and Safari. Two modes coexist: a no-code chat for everyone, and a built-in code editor for advanced users, with manual developer mode reserved for the Pro plan. You preview the result in an interactive mockup and refine it by chat. The deliverable is a downloadable extension folder you can load unpacked, and Extinde assists publication to the Chrome Web Store, Firefox Add-ons and Edge Add-ons. A library of free templates covers timers, tab management, AI summarizing and translation, screenshot capture and saving to Notion, and a community marketplace sells ready-made extensions, paying creators 85% of revenue. Pricing runs on credits: every generation, edit or export consumes them according to complexity, starting from a free tier of 25 credits.

- Download a browser-ready ZIP or publish on the Extinde marketplace
- Start from a free template instead of a blank page
- Open the generated source in the built-in code editor (manual developer mode on the Pro plan)
When to use Extinde / When not to
A quick filter to help you decide if Extinde is the right fit.
When to use Extinde
- Non-developers who want a working browser extension without writing a line of code
- Developers who would rather skip the boilerplate: manifest, icons and packaging
- Creators planning to sell on the Extinde marketplace, which pays them 85% of revenue
- Teams assembling internal browser utilities for their own workflows
- Anyone building everyday tools: productivity helpers, ad blockers, dark mode, tab management, AI summarizers and translators, screenshot capture, price tracking, note taking
When not to use Extinde
- Anyone who needs an API or programmatic access: none is announced
- Users looking for a mobile or desktop app, since Extinde is a web service only
- Organizations with enterprise procurement requirements, as no DPA, subprocessor list or SOC 2 / ISO certification is published
- Anyone planning what the terms forbid: malicious extensions, scraping without permission, spam, or breaching browser store policies
- Teams that need predictable per-build costs, because every generation, edit or export consumes credits and unused subscription credits reset each cycle

Pricing & Plans
Extinde runs on a credit model: every AI generation, edit or export consumes credits according to complexity. A free plan is available and includes 25 credits, roughly three small extensions, with no credit card required, multi-browser export and access to every template. The cheapest paid entry point is Starter at 9.99 USD per month for 250 credits per month. Builder costs 19.99 USD per month for 1,000 credits, priority AI models and access to marketplace payouts, while Pro costs 49.99 USD per month for 3,000 credits, Pro developer mode and its manual code editor. One-off credit top-ups can be bought on any paid account and are added to the current balance. Unused subscription credits reset at each billing cycle, whereas top-up credits do not expire while the subscription remains active. Payments are processed by Stripe. No annual discount, enterprise tier or quote on request is announced.

Data, GDPR & hosting
A consolidated view of how Extinde handles your data.
GDPR overview
Extinde's privacy policy explicitly addresses user rights under the GDPR and the CCPA, and offers the three practical ones: access, export and deletion, exercised from the dashboard or through support. That is where the published detail stops. No EU Article 27 representative is named, and no GDPR, legal or data-protection contact address appears anywhere on the site. There is no data processing agreement on offer and no list of subprocessors, Stripe being the only processor identified, for billing. No hosting jurisdiction is stated. The privacy page carries neither an effective date nor a last-updated date, so there is no way to tell which version applies. In short, the policy states GDPR rights but does not publish the surrounding machinery a European buyer would normally check.
Who owns the data?
Extinde's privacy policy says it collects account information (email, name), project data covering your prompts and the generated extension code, billing information processed by Stripe, and standard usage analytics. It grants you the right to access, export or delete that data at any time from the dashboard or by contacting support, which places day-to-day control in your hands. What the policy does not do is state who owns the generated extension code: neither the privacy policy nor the terms assign that ownership, so the question is left unaddressed rather than settled in either direction. No dedicated privacy contact address is published on the site.
Reuse rights
According to the privacy policy, Extinde uses the data it collects to run the service, generate extensions, deliver downloads, process payments and improve product quality, and it states explicitly that it does not sell personal data. Past that point the policy is silent on AI training: it neither claims that prompts and generated code feed model training nor promises that they do not, and no opt-out mechanism is offered or mentioned anywhere on the site. Users can export their own project data from the dashboard at any time; what they may then do with the extension code they generated is not restricted by the published documents, but it is not granted by them either.
Data retention & training
Hosting summary
Extinde publishes no hosting information at all. Neither the privacy policy nor any other page names a hosting country, a region, a cloud provider or a data centre, and no certification such as SOC 2 or ISO 27001 is claimed. The only processor identified anywhere on the site is Stripe, which handles payments. What is stored, according to the privacy policy, is account information, project data covering prompts and generated extension code, billing information and standard usage analytics; where it is stored is never stated. At network level the domain resolves behind Cloudflare (AS13335, an anycast address), which indicates where traffic is terminated rather than where the data lives, so no jurisdiction can be inferred from it. Buyers with a hosting requirement, whether European data residency, a named subprocessor list or a contractual commitment, will have to ask Extinde directly, and the site publishes no email address for that.
Things to keep in mind
Risks and trade-offs to weigh before adopting Extinde.
- Unused subscription credits reset at every billing cycle, so unused capacity is paid for and lost
- The credit cost of an extension varies with complexity and is quantified nowhere, which makes budgeting a guess
- The manual code editor is available only on the Pro plan at 49.99 USD per month
- No company name, postal address or contact email is published, which makes recourse difficult in a dispute
- Legal pages are brief and undated, with no DPA and no subprocessor list to inspect
- Nothing is published on whether prompts and generated extension code are used to train models
- You answer for what you ship: the terms forbid malicious extensions, scraping without permission, spam and store-policy breaches, and accounts that violate them can be suspended, while the marketplace keeps 15% of creator revenue
Setup & Integrations
Technical difficulty
Getting started is easy. There is nothing to install, since Extinde is a web service: you sign up and start describing your extension in plain English. The real friction sits downstream rather than upstream, in loading the finished extension unpacked in your browser and then taking it through each store's review process, for which Extinde supplies a publishing guide. The built-in code editor is there for advanced users and is never mandatory. Expect an easy start and a more demanding finish.

Should you pick Extinde?
Extinde is a legible product built around one clear need: making a browser extension without writing code. Pricing is public and coherent, and the 25-credit free tier is real enough to test before paying. The dual audience is deliberate, chat for non-developers and a code editor for developers, and one codebase exports to four browsers. The main reservation is transparency: no company name, address or contact email is published, the legal documents are brief and undated, and nothing is said about data hosting, retention or model training. The product is also very new, its domain registered in February 2026. Before committing, remember that the credit cost of an extension cannot be anticipated from the public pages.
