Pi Web

Free

Local web UI for the Pi coding agent — browse sessions, switch worktrees, manage models, and chat beside your project files in a browser.

Key features

  • Session Browser: Reads local Pi session files and organizes prior conversations by project for quick resume.
  • Fork and Continue: Continue from any earlier message or fork a session into a separate route to try alternatives safely.
  • Git Worktree Switcher: Switch between Git worktrees from the sidebar to work on multiple branches in parallel.
  • File Preview: Side-by-side chat and project file browser that previews source, docs, images, audio, and PDFs.
  • Model and Skill Manager: Configure models, API keys, run model tests, and toggle skills from the web UI instead of CLI flags.
  • Local-Only Runtime: Runs on http://127.0.0.1 by default so session data and code never leave the developer's machine.

Best for

  • Resume Prior Work: Reopen a conversation from last week by project instead of scrolling terminal history.
  • Safe Experimentation: Fork a session to try a risky refactor without losing the original conversation state.
  • Parallel Branch Work: Switch Git worktrees mid-session to jump between feature branches in one workspace.
  • Model Comparison: Rerun the same task against different configured models to compare output quality.
  • In-Browser Code Review: Preview generated diffs and project files beside the chat without leaving the browser.

Key features

  • Real-time Search Engine: Low-latency, relevance-optimized web search API that returns contextual results tailored for LLM consumption and agent workflows.
  • Intelligent Content Extraction: Extracts structured data and summarized content from URLs, returning relevant passages, metadata, and evidence for use in RAG and agent responses.
  • Crawl and Map Capabilities: Configurable site crawling with depth/limit and instruction controls to discover, index, and map site structure and content for downstream use.
  • Ranked Results and Filtering: AI-driven ranking and filtering options (topics, domains, date ranges, result limits) to prioritize the most relevant web content for queries.
  • SDKs and Language Support: Official client libraries (Python and TypeScript/JavaScript) and examples for quick integration into applications, agents, and MCP servers.
  • MCP Integration Tools: Atomic tool endpoints (e.g., web_search, answer_search, news_search) and example MCP servers to expose Tavily search capabilities to LLM toolchains.
  • Credit-Based Usage Model: API access controlled via API keys and credits, with documentation and client wrappers that surface credits usage and request parameters.
