Download links become available on your order page after SellAuth confirms payment. Cryptocurrency confirmation times vary. Extract all files from the ZIP, then read START-HERE.html or the included setup guide. If the download is missing after confirmation, open a ticket with your order ID.
Litecoin (LTC) is currently enabled. Use the currency, network, amount and payment address shown on your order page. Card payments and USDC are not currently enabled in this store. Your order page contains the payment instructions for that purchase.
Choose CSV Workbench to clean UTF-8 CSV files; JSON Desk to validate JSON and use JSON Pointers; Image Batch to resize and convert images; Invoice Desk for invoices and quotes; API Probe to test JSON endpoints; Studio Launch for an editable EN/RU website. Text Review, Regex Lab, Campaign Links, Timezone Desk and Community Event Desk cover comparison, text patterns, campaign URLs, meetings and event planning. Read each product page for limits and examples.
You receive the downloadable product files, editable source, included instructions and the license stated on its product page. There is no monthly subscription. The purchase licenses the selected product. Custom development, hosting, domains and integrations are not included.
The browser tools run locally in a current desktop browser after you extract the ZIP; they process your inputs locally. API Probe requires Node.js 20+ and intentionally sends GET requests to the public endpoints you configure. Studio Launch is editable HTML/CSS; putting the website online requires your own hosting. Product pages list individual file limits and browser requirements.
Both are delivered in data-tools-v1.0.zip. Your purchase licenses only the product shown on your receipt; the other tool requires a separate paid purchase. Extract the complete archive and open START-HERE.html, then the instructions for your purchased module.
