Auto-capture undocumented API endpoints as SDK
The Problem
Developers and indie hackers reverse-engineering undocumented APIs via browser DevTools network tabs spend hours manually logging requests, extracting endpoints, parameters, and auth patterns before writing SDK code. Surveys of top reverse engineering tools show dominant usage of IDA Pro, Ghidra, Binary Ninja, and Frida by cybersecurity pros and researchers, but none automate web API capture-to-SDK workflow, forcing fragmented toolchains. These devs currently spend $99-$1499+ on binary-focused RE tools or enterprise API platforms like Apigee without web-specific automation.

spending hours reverse-engineering undocumented APIs via DevTools
Core Insight
Automates DevTools network request capture to generate clean, ready-to-use SDK code for undocumented APIs, filling gaps in binary-focused tools (no web support) and enterprise platforms (no reverse-engineering automation).
- Target Customer
- Indie hackers and solo API integrators reverse-engineering undocumented endpoints in SaaS/web apps (e.g., mobile/IoT security researchers using Frida); market includes 100k+ active reverse engineers per 2026 tool surveys, with growing devtools demand.
- Revenue Model
- Tiered SaaS: Free tier for basic capture (like Ghidra/Frida), Pro at $99/year for SDK generation (matching Hopper personal), Enterprise $1499+/year for teams/advanced features (aligned with Binary Ninja)
Competitive Landscape
Free (open source)
Frida excels at dynamic instrumentation for injecting scripts into running processes but lacks automated capture of undocumented HTTP API endpoints from browser DevTools network requests and direct generation of SDK code. Developers must manually script and interpret network traces.
From $1499 (commercial license)
Binary Ninja focuses on binary disassembly and decompilation for security researchers but does not support capturing live web network requests or generating SDKs for undocumented REST APIs observed in browser DevTools. It requires manual export and coding for API integration.
From $99 (one-time personal license)
Hopper provides native macOS UI for binary reverse engineering and disassembly but misses browser-based network request capture for web APIs and automated SDK code generation. Users need additional tools for web API discovery.
Usage-based (pay-as-you-go starting at ~$0.01 per API call, enterprise plans custom)
Apigee offers enterprise API management with design, security, and monitoring for known APIs but does not auto-capture undocumented endpoints from DevTools reverse-engineering sessions or generate client SDK code. It targets managed APIs, not ad-hoc discovery.
Custom enterprise pricing (typically $1000s for licenses)
IDA Pro is a leading interactive disassembler for binary analysis in cybersecurity but lacks features for capturing web network traffic or auto-generating SDKs from undocumented API endpoints found via DevTools. It focuses on static/dynamic binary RE, not web APIs.
