C3

Cloud Claude Code

Claude Code, from any browser. Autonomous agents, from any channel.

Your Sessions, From Anywhere

Every session is visible in one place. Agents that ran overnight, debugging sessions from your phone, all in one list.

Remote Sessions

Pilot Claude Code from your phone, tablet, or any browser. Your machine does the work. You just steer.

Autonomous Triggers

A Slack message starts an investigation. A Discord alert triggers a fix. Agents run while you sleep, and report back.

Real Conversation, Real Tools

C3 streams Claude Code's full output: thinking, tool calls, file edits, test results. Everything you'd see in the terminal.

C

Found the issue. The aggregateMetrics() function runs a full table scan on every request because the created_at index was dropped in the last migration.

Two changes made:

  1. Restored the composite index on (created_at, metric_type)
  2. Added a 5 minute cache with stale-while-revalidate for the aggregation endpoint

Query time dropped from ~1200ms to ~8ms. All tests pass.

How It Works

C3 Architecture: Slack/Discord alert triggers C3, which auto-starts a Claude Code session that investigates, fixes, and reports back. You monitor from your browser.
