After months of development, we're excited to share it with the community.</p> <h2> What it does </h2> <ul> <li> <strong>SSRF-guarded web extraction</strong> (browse, extract, crawl) via clean REST API</li> <li> <strong>Built-in AI mode</strong>: query fan-out, grounded citations, multi-model router</li> <li> <strong>Adblocking</strong>: EasyList + EasyPrivacy compiled to binary automata (ABP + uBlock syntax)</li> <li> <strong>Tracker blocking</strong>: 60+ tracker domains blocked natively</li> <li> <strong>Crash recovery</strong>: sessions auto-persist, never lose tabs</li> <li> <strong>Memory saver</strong>: inactive tabs hibernate automatically</li> <li> <strong>Zero telemetry</strong>, zero data collection, <strong>BYOK</strong> (your keys stay local)</li> <li> <strong>Web UI control panel</strong> + MCP tool server (WebMCP-ready)</li> <li>8 languages, RTL support, session record/replay</li> </ul> <h2> What we DON'T do (on purpose) </h2> <ul> <li>No stealth/anti-detection for bypassing paywalls or bot walls</li> <li>No residential proxies or CAPTCHA solving</li> <li>No user tracking, ever</li> </ul> <h2> Tech stack </h2> <p>Python + CDP (Chrome DevTools Protocol), PyQt6 WebEngine for the UI layer, FastAPI for the REST API. 802 tests, TDD-developed, MIT licensed.</p> <h2> Architecture </h2> <p>Three layers:</p> <ol> <li> <strong>CDP Driver</strong> — Chromium control via Chrome DevTools Protocol</li> <li> <strong>Brand Engine</strong> — PyQt6 WebEngine for the native UI</li> <li> <strong>API Layer</strong> — FastAPI REST API for programmatic access</li> </ol> <p>The adblocking engine uses Aho-Corasick + Wu-Manber algorithms on compiled binary automata for high-performance pattern matching.</p> <h2> Try it </h2> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>git clone https://github.com/sametatakan0000-netizen/pergel <span class="nb">cd </span>pergel pip <span class="nb">install</span> <span class="nt">-e</span> <span class="nb">.</span> python <span class="nt">-m</span> src.main </code></pre> </div> <p>Would love feedback on the architecture — especially the SSRF-guarded extraction pipeline and the Pareto-dominance model router.</p> <h1> opensource #python #privacy #ai #browser </h1> privacy agents opensource ai
