ToneKit - Sell Project

ToneKit Overview ToneKit is a fully developed, production-ready audio processing SaaS that lets users convert, trim, merge, compress, clean, and visualize audio files directly in their browser with no uploads, no tracking, and no backend processing. The entire platform is functional, polished, and designed to start generating revenue immediately. It includes email authentication, Stripe subscriptions, three pricing tiers, 7-day free trials, monthly usage limits, and a responsive dashboard. All tools are integrated, tested, and working end-to-end. Audio Tools Included ToneKit provides six powerful, browser-based audio tools: Audio Converter (MP3, WAV, OGG), Audio Trimmer for precise edits, Audio Merger to combine multiple files, Dynamic Range Compressor for smoother volume, Noise Reduction Tool to remove hiss, and a Waveform Viewer with visual playback. All processing is done locally using ffmpeg.wasm and the Web Audio API for speed and privacy. Monetization System ToneKit is built for recurring revenue using Stripe Billing. It offers three subscription plans: Starter with 100 conversions/month, Pro with 500, and Unlimited with no limits. All plans include a 7-day free trial. Monthly usage is tracked automatically, subscription billing is fully integrated, and upgrade prompts appear when users reach their limit. No manual billing logic is required. Authentication & User Accounts The platform includes email/password authentication, secure session handling, and a complete account dashboard. Users can view their plan, trial status, usage, and settings. Everything works instantly after signup with no configuration required. UI and User Experience ToneKit has a modern dark-theme interface with gold accents, fast onboarding, a mobile-responsive dashboard, sidebar navigation for tools, a real-time status bar for processing feedback, and smooth transitions throughout the app. The UI feels like a polished, production-grade SaaS. Tech Stack The project is built with HTML, CSS, JavaScript, Node.js, Express, ffmpeg.wasm for client-side audio processing, and the Web Audio API for waveform visualization. Stripe Checkout and Stripe Billing handle subscriptions, and a lightweight database is used for users, plans, and usage tracking. The project is fully deployable on Vercel or any Node-compatible environment. Included With Purchase Buyers receive the full source code, ToneKit branding assets, all audio tools, Stripe subscription integration, the usage-limit system, the dashboard and settings pages, the responsive landing and pricing pages, deployment documentation, Stripe webhook instructions, and optional post-sale support. Everything is structured for a smooth transfer. Why ToneKit Is Valuable This is a complete, monetizable SaaS, not a demo.
