The Lightpanda Browser is an open-source, headless browser developed by lightpanda-io, designed for AI and automation tasks. Written in Zig, it emphasizes performance with a low memory footprint and fast execution. It supports automation tools via the Chrome DevTools Protocol but lacks full Web API support. The project is in beta, with active development and community interest, as evidenced by 1,216 commits and numerous branches and issues. The trajectory suggests ongoing feature development and integration improvements.

Risk | Level (1-5) | Rationale |
---|---|---|
Delivery | 4 | The project faces significant delivery risks due to a backlog of unresolved issues (#379, #366) and incomplete pull requests (#194, #244). The high dependency on Pierre Tachoire for contributions further exacerbates this risk. Additionally, critical bugs like the non-working example in the README (#379) could delay delivery if not resolved promptly. |
Velocity | 4 | Velocity is at risk due to the uneven distribution of work among developers, with Pierre Tachoire being the primary contributor. Prolonged inactivity on several pull requests (#315, #244) and the accumulation of unresolved issues indicate potential bottlenecks in the development process. The lack of assigned reviewers for key pull requests further contributes to this risk. |
Dependency | 3 | The project relies heavily on external dependencies such as jsruntime and netsurf, which pose risks if these dependencies are not maintained or updated regularly. Additionally, blocked pull requests due to dependencies on other changes (#367, #356) highlight potential delays in project progress. |
Team | 3 | Team risks are moderate due to the heavy reliance on a single contributor, Pierre Tachoire, which could lead to burnout or bottlenecks if he becomes unavailable. Limited contributions from other team members suggest potential workload distribution issues that could impact team dynamics and project velocity. |
Code Quality | 3 | Code quality is at moderate risk due to incomplete implementations and unresolved review comments in several pull requests (#176, #194). The presence of TODOs in critical files like src/server.zig indicates areas where improvements are needed to maintain high code quality standards. |
Technical Debt | 3 | Technical debt is accumulating due to incomplete features and unresolved issues. The presence of TODO comments in key files like src/dom/document.zig and src/server.zig suggests areas where technical debt could increase if not addressed promptly. |
Test Coverage | 3 | Test coverage is moderate but could be improved. While there is extensive test coverage for certain modules like src/dom/document.zig, gaps remain due to blocked or incomplete tests. The lack of tests for edge cases in src/http/Client.zig also poses risks. |
Error Handling | 3 | Error handling is generally robust across the codebase, with specific error types defined for various operations. However, critical issues like unreachable DOMErr codes (#366) indicate potential gaps that need addressing to ensure comprehensive error handling. |
Recent GitHub issue activity for the Lightpanda Browser project shows a mix of bug reports, feature requests, and discussions on enhancements. Notably, there are several issues related to compatibility with automation tools like Puppeteer and Playwright, indicating ongoing efforts to improve integration with these tools. Issues such as #379, where the example in the README does not work, and #375, discussing remote page support, highlight challenges in usability and feature completeness. There are also multiple bug reports concerning crashes and errors when interacting with specific web APIs or using certain functionalities, such as #366 (Unreachable DOMErr code) and #365 (Cannot get page content using Puppeteer).
A recurring theme is the need for better support of Web APIs and handling of various JavaScript execution scenarios. Issues like #358 (Location API) and #263 ([i]frame support) point to gaps in the current implementation that affect compatibility with modern web applications. Additionally, there are ongoing discussions about enhancing the browser's capabilities, such as upgrading dependencies (#372: Upgrade to zig 0.14.0) and expanding platform support (#369: Windows Support?).
The issues reflect a focus on addressing critical bugs that affect user experience and functionality. The high-priority issues often relate to core functionalities like example scripts not working or integration problems with popular automation frameworks. The project's active development is evident from frequent updates and community engagement through comments and discussions on these issues.

The Lightpanda Browser project demonstrates active development with several open pull requests addressing both new features and existing bugs. However, some older pull requests are notably stalled, suggesting either technical challenges or deprioritization. Recent closed pull requests indicate ongoing maintenance and improvements in documentation and dependency management.
