Managed hosting giving every customer their own always-on agent in a persistent sandbox.
Agent 37 is a cloud platform for running AI agent harnesses — Hermes, OpenClaw, Claude Code, Codex, OpenCode, and Grok — in persistent sandboxes that keep files, memory, and tools between sessions. Developers pick a harness and Agent 37 handles hosting, starting and stopping environments, access controls, and backups; for agent products, one API call provisions a separate isolated sandbox per customer. The Agent37 Gateway exposes a single Responses-style API that routes each turn to whichever harness is behind the instance, so client code stays constant. It claims roughly 95% lower sandbox cost than alternatives by running its own hosting stack.

The right coding tool depends on where you write code and how much of your codebase it can understand. IDE integration is the first filter — a tool that lives in your editor, sees your project files and respects your stack will help far more than a general chatbot you paste snippets into. Look for accurate completions, clear explanations of suggested changes, and strong refactoring and debugging support for your main languages. Privacy deserves real attention: check whether your code is used for training, and whether a self-hosted or enterprise option exists for sensitive projects. Price against the hours it actually saves — most developers feel the difference within the first week of real use.

Best for: AI agent developers who need fast, light browser fetching, extraction and automation
Pricing: Open Source
Limitation: Full visual capabilities need the --layout flag

Best for: Claude Code users juggling several agent sessions who want to see and answer them from the notch
Pricing: Open Source
Limitation: Mac only — macOS 15 or later, and made for MacBooks with a notch

Usage guard for Claude Code and Codex: set weekly, daily or per-project limits and it warns, asks or pauses the agent before the week's allowance burns out, from the terminal or a Mac menu-bar app
Best for: Claude Code and Codex users who keep burning their weekly allowance early
Pricing: Freemium
Limitation: Stale readings can make a pause late, and requests already in flight or tools outside hook coverage are not stopped

Best for: Developers who run coding agents in tmux and want to steer them from their phone
Pricing: Open Source
Limitation: The phone app is Android-only; iPhone users must use the browser hub instead
