Plexus

AI Agent Observability Platform

Running multiple AI agents?

Managing Claude Code, Cursor, and Gemini CLI across projects gets chaotic fast.

Lost in terminal tabs

Switching between 5+ terminal windows to check agent status. Which one was working on the API refactor again?

Missed permission prompts

Agent has been waiting for approval for 20 minutes while you were focused on another task. Productivity lost.

Surprise API bills

No visibility into token usage across agents. That experimental prompt just cost $15 and you didn't even notice.

Monitoring

Fleet View

Monitor all your AI agent sessions in a unified grid. See status, recent output, and elapsed time at a glance.

Control

  • Focus Terminal

    Instantly jump from Plexus to the terminal where your agent is working. Double-click or press Enter to switch windows — supports tmux, terminal emulators, and Cursor IDE.

  • Smart Notifications

    Get notified about permission requests and session completions. Supports Slack, Discord webhooks and click-to-focus.

Analytics

  • Cost Intelligence

    Track API costs across Claude, Gemini, and Cursor. See spending trends and project-level breakdowns.

  • Productivity Insights

    Analyze your patterns with heatmaps, frequent prompts, and failure detection across all sessions.

Replay

Session Replay

Replay any past session to review the complete agent interaction sequence. Step through each message, tool call, and response to understand exactly what happened.

History

  • Session Archive

    Browse and search past sessions with full conversation logs, tool executions, and outputs.

Integration

  • Multi-Agent Support

    Claude Code, Cursor, Gemini CLI, and tmux sessions — monitor and control them all from one place.

  • Keyboard-First

    Vim-style navigation with A/R for approve/reject, J/K for navigation, and a full shortcut cheatsheet.

Privacy

Local-First

All data stored in SQLite on your machine. No cloud sync, no tracking, no third-party access.

Open Source

Fully open source and free to use. Inspect the code, contribute, or fork it for your needs.
