Most browser extension developers ship the same product to Chrome, Edge, and Firefox, then try to track its performance across three separate developer dashboards, three different review feeds, and three sets of keyword rankings. The data is fragmented, history is short, and there is no easy way to compare a release against a competitor over time.
Exstats fixes this by grouping the Chrome, Edge, and Firefox versions of an extension into one product view, alongside the competitors you want to watch. It tracks daily changes in installs, ratings, reviews, category rank, and search rank, then keeps up to a full year of history so weekly and monthly trends are visible at a glance. Email and Slack alerts fire on rating drops, rank shifts, and competitor updates so a regression does not sit unnoticed for a week.
Beyond your own products, the Extension Explorer indexes 280,000+ extensions with 30+ searchable fields and exportable CSV or XLSX, the Keyword Tracker suggests AI-generated keyword ideas and tracks rank by store, and the Store Trends dashboard reports category growth, rating distributions, and review activity across each store.
Split Fee is a platform for UK recruitment agencies to collaborate on permanent placements.
Every agency has candidates they can't place and vacancies they can't fill. Another agency almost certainly has what you need โ but finding them, trusting them, and making the collaboration work has always been the hard part.
Split Fee solves this. Post your candidates and vacancies to the platform. Our matching algorithm finds opportunities across every agency on the network โ by skills, location, salary, and seniority. Candidate and client data stays anonymised until both sides agree to work together. When a placement is made, we handle the fee split and invoicing automatically.
No more posting in social media groups and hoping someone replies. No more sharing candidate details with strangers on trust alone. No more chasing invoices from agencies you barely know.
45% for you. 45% for them. 10% platform fee โ only when a placement is made.
Half of a placement fee is infinitely better than none of it.

Split Fee's answer:
A next-generation serverless platform, built for AWS.
Exstats's answer
Exstats treats an extension as one product across stores, not as three separate listings on three sites. The Chrome, Edge, and Firefox versions sit in one row, and history, reviews, alerts, and competitor data flow from there.
Split Fee's answer:
Split Fee is the first purpose-built platform for split fee recruitment in the UK. Instead of relying on LinkedIn groups, WhatsApp messages, and manual agreements, agencies upload their candidates and vacancies and the platform automatically matches them across agencies.
Candidate identities are revealed gradually; anonymised at first, then progressively disclosed as both sides accept, so agencies can collaborate without the risk of circumvention.
Exstats's answer
Unified multi-browser view. Exstats is the only dashboard that groups the Chrome, Edge, and Firefox versions of an extension into one product, with shared history and shared alerts. Most analytics tools cover only the Chrome Web Store, or split the three stores across separate sites.
Full year of daily history. Stores show current numbers and a short trail. Exstats keeps daily snapshots for up to a year so weekly and monthly trends, rating regressions, and competitor launches are visible at a glance.
Reviews from every store in one table. Chrome, Edge, and Firefox reviews sit in one sortable, filterable table, so a developer can read a week of feedback without rotating between three dashboards.
Keyword tracking with AI suggestions. Search rank is tracked per store with daily change indicators, and the keyword tool suggests new keywords from competitor listings rather than expecting the developer to bring a complete list.
Split Fee's answer:
Most "split fee networks" are just directories or social groups where agencies post and hope someone responds. Split Fee is an actual matching engine. It scores candidate-vacancy pairs, handles the legal agreements (non-circumvention, self-billing), automates invoicing and fee splits, and manages the entire placement lifecycle from match to payment. Everything that normally requires trust, phone calls, and spreadsheets is handled by the platform.
Exstats's answer
Exstats is built for the people shipping and growing browser extensions.
The core audience is independent extension developers and small product teams who need one place to watch installs, ratings, reviews, and keyword rank for their extensions, on whichever stores they publish to.
A second audience is extension growth and marketing specialists who track competitor launches, rating shifts, and category trends on behalf of clients and need a single view across Chrome, Edge, and Firefox rather than three separate workflows.
A third audience is product and engineering teams at companies whose extension is a meaningful acquisition or retention surface, who need daily alerts, exportable data, and API access for internal dashboards.
Split Fee's answer:
UK recruitment agencies; from boutique firms with a handful of consultants to mid-sized agencies with specialist sector coverage. Any agency that has either strong candidates without the right vacancies, or client vacancies they can't fill from their own candidate pool. Split Fee turns those dormant assets into placements.
Exstats's answer
Exstats started because developers shipping browser extensions kept running into the same wall. The Chrome Web Store, Edge Add-ons, and Firefox Add-ons each give publishers a siloed view with short history, no competitor data, and no way to compare a release against a rival over time. Teams that maintained extensions on more than one store ended up checking three dashboards a day and keeping competitor numbers in spreadsheets. We built Exstats so an extension and its store versions live in one place, with daily history, alerts, and competitor tracking built in.
Split Fee's answer:
Abbie, our founder, knew that although split fee arrangements have existed in recruitment for decades, the process has always been manual: find a partner agency, negotiate terms, trust them with your candidate data, chase invoices. Most agencies avoid it because the overhead and risk outweigh the reward. Abbie built Split Fee to remove that friction entirely, with automated matching, progressive identity disclosure, built-in legal agreements, and automated billing, making split placements as straightforward as direct ones.
