The short verdict

handup is the right tool for a solo developer who runs agentic coding workflows and wants a single place to approve or block consequential actions before they happen. It does one thing and does it with real depth: previews are hash-bound to the exact content you approved, denials reach the agent as structured feedback rather than errors, and the Android app wakes even when closed. The tradeoff is that team licensing does not exist yet, and the planned managed relay is not available for purchase, so anyone who needs multi-seat access or a hosted relay today will hit a hard wall.

What is handup?

handup is an approval inbox for AI coding agents. When an agent wants to do something consequential, like run a database migration, push a release or send an email, it sends a request with the real thing attached: the command, the diff, the file, the email draft or an image. You approve it, or deny it with feedback such as "use staging instead", from `handup inbox` in the terminal, the desktop app or the Android app. A denial reaches the agent as a normal answer, so it changes course instead of retrying.

Runs on Linux, macOS and Windows (beta) with an Android companion. 14 days free with every feature and no signup, then $30 one-time per person, released updates included, 30-day refunds.

How we scored handup

Capability scores well because the hash-bound approval mechanism, structured denial feedback, and multi-surface inbox (terminal, desktop, Android with push) are genuinely differentiated features not found in the directory competitors. It loses points because team licensing is absent entirely and the managed relay is not yet available, leaving real gaps for any workflow beyond a single developer. Ease of use is strong: a 14-day no-signup trial, a single handup setup command that auto-detects agents, and QR-code phone pairing keep onboarding friction low, though Windows beta status and the self-hosted relay requirement add friction for some users. Value is the clearest strength: $30 one-time with perpetual use and all future updates included is genuinely fair pricing for a developer tool, and the 30-day refund policy removes purchase risk. Delivery scores low because handup is a self-described beta with a very thin public track record: no substantial independent reviews were found, the managed relay is unshipped, Windows support is unsigned and beta, and the product's own pricing page explicitly states no guarantee of indefinite development, which is an honest disclosure but a real uncertainty for buyers.

Pros and cons

What we liked

  • Hash-bound approvals tie your decision to the exact content you reviewed, preventing agents from substituting a different command after approval
  • Denials return structured feedback to the agent so it revises and asks again rather than erroring out, keeping agentic workflows moving
  • 14-day fully featured trial with no account or credit card, and a $30 one-time price with no subscription and a 30-day refund window

Where it falls short

  • Team licensing does not exist yet, so a two-person team cannot share an approval queue at any price
  • The managed relay for reaching your phone without running a server is planned but not for sale; you must run the relay binary on your own Linux server today
  • Windows support is beta and unsigned, requiring users to click through SmartScreen warnings during installation

Key features

MCP-native agent integration
A single MCP server connects to Claude Code, Codex, Cursor, omp, opencode, and any other MCP-compatible client. The handup integrate command auto-detects installed agents and wires them up in one step.
Real-artifact previews
Agents attach the actual command, diff, file, email draft, or image to each request. You review the real thing, not a description of it, before deciding.
Hash-bound approvals
Each approval is cryptographically bound to the content you saw. An agent cannot substitute a different payload after you have approved a specific artifact.
Structured denial with feedback
Denying a request sends your note back to the agent as a normal answer. The agent revises and asks again rather than throwing an error or retrying the same action.
Multi-surface inbox
Approve or deny from the terminal (handup inbox), the desktop app, a local web inbox, or the Android app. The Android app receives push notifications even when closed, via the licensed push gateway.
Self-hosted relay
Phone pairing works over Tailscale by default. For reaching your phone without Tailscale, you can run the handup-relay binary on your own Linux server; the relay is end-to-end encrypted and never sees previews or decisions.
Audit history and request management
A searchable History view records every decision with outcome, kind, and agent filters. Individual requests can be deleted from the inbox, terminal, or Android app, with pending requests cancelled before removal.
Automated decision cookbook
A local HTTP API and CLI let scripts and CI pipelines send approval requests or automate routine decisions without human input, covering non-interactive workflows.

Who should use handup?

handup is built for the solo developer who has moved beyond single-agent workflows and now runs several agents in parallel, Claude Code in one terminal, Codex in another, and wants one place to catch the moments that matter before they become incidents. If you have ever let an agent push a migration to production because you were not watching closely enough, this is the tool that puts that checkpoint back in your hands without forcing you to babysit a terminal.

It is also a reasonable fit for any developer who works from their phone during the day and wants to approve or block agent actions without being at a desk. The Android push gateway, which went live in v0.1.7, means your phone wakes when an agent asks even if the app is closed.

If you need shared approval queues across a team, look elsewhere for now. GitHub Copilot's agentic workflows inside VS Code handle multi-developer environments and have the backing of an established platform. If you want a fully managed, no-server-required setup today, handup's relay is self-hosted only, and that gap is real.

Frequently asked questions

Does handup require an internet connection or a cloud account to work?+

No cloud account is required. The 14-day trial needs no signup. After purchase, you activate with a license key from Polar using handup license activate. Phone pairing works over Tailscale or a self-hosted relay; no hosted service is included in the personal license.

What does the $30 one-time price actually cover?+

One person on all the machines they personally use, perpetual use of the versions they receive, and every handup update that is released going forward. It does not promise indefinite development or include any hosted relay service.

Can I use handup with my team?+

Not yet. Team licensing is not offered. The personal license covers one person only and must not be shared.

How does the Android app get notified when an agent asks for approval?+

As of v0.1.7, license holders using the official Android app get push notifications through a licensed push gateway at push.gethandup.dev. The phone registers a proof-of-possession device ticket, so only verified phones receive wake-up notifications. The app wakes even when closed.

What happens if I deny a request?+

Your denial and any note you add are returned to the agent as a normal structured answer. The agent treats it as feedback, revises its approach, and can ask again rather than throwing an error or retrying the same action.

Is there a refund policy?+

Yes. You can request a full refund within 30 days of purchase, no reason needed, by contacting support or replying to the Polar order email.
