Latest News
Reverse API Engineer v0.14.0 released with PowerShell 7+ output, live client validation, Windows compatibility fixes, and dependency-security updates.
Reverse API Engineer v0.13.1 fixed fresh-install failures by explicitly using httpx2 and declaring the dependency.
Reverse API Engineer v0.13.0 added the client_executed JSON-stream event and slimmer source distributions.
Reverse API Engineer v0.12.0 made Playwright optional for manual mode and reduced the base installation footprint.
Products & Services
An open-source CLI that lets a user or AI agent browse a website, capture browser requests and responses in a HAR, and generate a production-ready typed API client. It supports agent, manual, engineer, and collector modes and outputs Python, JavaScript, TypeScript, Go, Java, C#, PHP, Ruby, C, and PowerShell.
An AI job-search product/data platform with an open dataset, live map, and open agent; the portfolio links its website, GitHub repository, and demo.
A map and aggregator of jobs at top AI companies; the Reverse API Engineer article says it motivated the need to collect ATS/job data.
A browser-agent evaluation platform for realistic web tasks, comparing agents on speed, reliability, cost, task completion quality, and ELO-style rankings.
Market Position
Reverse API Engineer is positioned as an open-source, local alternative to manually inspecting DevTools/cURL or relying on brittle selectors and scraping. Kalil's technical write-up explicitly contrasts the workflow with browser-use and Stagehand, emphasizing native HAR capture, agent-driven browsing, and direct typed-client generation rather than a two-step automation-plus-codegen pipeline.
Leadership
Founders
Kalil Sama Bouzigues
Computer-science and cybersecurity researcher and builder; pursuing a master's degree at EPFL with a semester at ETH Zurich through a dual-diploma exchange. He is a pre-doctoral researcher focused on browser-agent evaluation, web automation benchmarks, and agent reliability, and is a top contributor to browser-use.
Executive Team
Kalil Sama Bouzigues
Independent developer, researcher, and creator
EPFL master's student with an ETH Zurich dual-diploma exchange semester and a pre-doctoral researcher role at Agentic Systems Lab; builds Stapply, Browser Arena, and Reverse API Engineer and contributes to browser-use.
Founding Story
The portfolio does not state a formal company founding. Kalil's Reverse API Engineer project began while building Stapply Map, a job aggregator requiring data from undocumented ATS APIs: after repeatedly inspecting browser traffic, copying requests into Claude, and manually creating clients, he decided to automate the workflow. The initial vision was to capture browser traffic and have an AI system generate a usable API client, later adding autonomous agent mode.
Business Model
Revenue Model
The publicly described Reverse API Engineer offering is open-source and MIT licensed, runs locally, has no account/server/analytics requirement, and states that there are no fees. No paid subscription, API-usage billing, or other monetization model is described for kalil0321's projects.
Pricing Tiers
MIT-licensed open-source CLI; installable with uv or pip and usable locally.
