## NapCat

NapCat occupies the space Apple leaves around the MacBook camera and turns it into a control surface for AI-assisted development. Each running agent session becomes a row showing whether it is working, waiting on you, or done, and clicking that row returns you to the exact session and thread. Claude Code and Codex receive the deepest integration, including local context, lifecycle events, and exact task return; other recognized agent CLIs are picked up at process level.

The permission side is what many developers actually value. Claude Code permission requests and structured MCP elicitation forms appear in the notch, so a small decision can be resolved without switching windows. Typed or secret input opens a native form once you click through. Outside of agent monitoring, the same island hosts media controls, shortuts, a 25- or 50-minute focus timer, and a nap screen that blacks out your displays while builds keep running.

NapCat is deliberately local-first. Monitoring and the Activity view run on your machine, no server is required, and prompts, responses, project names, and paths are not transmitted. The optional Claude usage meter reads directly from Anthropic through your existing Claude Code login, and product analytics is off unless you enable it. The app is free with no account, license key, or trial clock, distributed as a signed DMG that updates automatically.

**Pricing & Plans:** NapCat is completely free. There is no account, license key, trial clock, or paid tier, and the download includes every feature.

- **Live agent status in the notch:** See at a glance which of your AI coding sessions are working, which need you, and which finished, with stable identities across CLI and desktop threads.
- **Exact session return:** Click a row in the notch to jump back to the precise Claude Code or Codex session and thread, instead of hunting through terminals and windows.
- **Claude Code permissions and input forms:** Review permission requests and structured MCP elicitation forms from the notch; simple choices resolve inline while typed or secret fields open a native form.
- **Screen naps and keep-awake:** Cover your displays with a private nap screen while builds and downloads continue in the background, with keep-awake holding off sleep and the lock timer.
- **Local activity history:** A private contribution-style map on your Mac records daily agent time, session, prompt, and completed-work totals, with configurable history retention.

**Strengths:** Completely free with no account, license key, or upsell; Local-first: prompts, responses, and project paths stay on the machine; Exact session return saves real time when many agents run at once; Handles Claude Code permission prompts and MCP input forms in the notch

**Limitations:** Requires macOS 13 or later on Apple Silicon; Notch-oriented UI is less compelling on Macs without a physical notch; Rich context is deepest for Claude Code and Codex; other CLIs only show process-level status

## Raindrop

Agents fail differently from normal software. A run can complete without any exception while still producing the wrong answer, calling the wrong tool, or looping on a failed retry. Raindrop is designed around that reality: it records each message, tool call and decision as a trace, then looks for patterns across many runs so a recurring problem becomes a single, trackable issue with severity, affected user counts and confidence.

The workflow moves from signal to fix. Teams trace an individual run to see exactly where things went wrong, use the triage agent to investigate and automate work in Slack, the web app or via MCP, and then run simulations on a pull request to see what a change would do before merging. A comparison view checks the change against real traffic so you can confirm which behaviours improved rather than guessing. A local Workshop tool lets engineers inspect, replay and debug agents on their own machines.

Raindrop covers both monitoring and pre-release testing, which makes it useful for teams shipping agents to large audiences — the site notes customers running agents used by millions of users. Because the space moves quickly, feature names and packaging may change; check the site and docs for the current scope, and note that the company has raised a $50m Series A, a signal of continued investment.

**Pricing & Plans:** Raindrop offers a free starting tier with no credit card required for individual developers and small teams, plus paid plans for larger usage, an enterprise option, and a free programme for teams building agents for social good. Exact seat and usage pricing is on the pricing page and can change, so confirm there before committing.

- **Agent tracing:** See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
- **Automatic issue detection:** Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
- **Triage agent and integrations:** An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
- **Simulations in CI:** Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.
- **Local Workshop debugger:** Inspect, replay and debug agent behaviour locally without round-tripping through production.

**Strengths:** Purpose-built for agent traces and non-throwing failures, not generic APM; Covers the full loop from detection to investigation to simulation; Triage agent works inside Slack, web and MCP where teams already operate; Free starting tier and no credit card required to begin

**Limitations:** Aimed at teams already running agents in production, which is a narrowing audience; Advanced simulation and enterprise capabilities sit behind paid and enterprise plans; Fast-moving product surface means some features may shift or be labelled beta
