Omnara vs Happy vs SeaWork (2026): Claude Code Remote Control Apps Compared

Omnara, Happy, and SeaWork all solve the same job: leave your desk without freezing a long Claude Code or Codex run — monitor the session, answer approvals, and steer from a phone or browser. They are remote control surfaces, not new coding models. Architecture, agent coverage, encryption story, and how much product sits around the remote link differ. Choose by workflow, not by who shouted loudest on Twitter.

This comparison is for people searching Omnara, Happy Coder / happy.engineering, or Claude Code mobile who want a three-way map. Product pages change — treat feature rows as July 2026 snapshots and re-check each site before you depend on a claim.

Side-by-side table

Dimension	Omnara	Happy	SeaWork
Agents supported	Claude Code + Codex (per remote.omnara.com FAQ)	Claude Code + Codex (per GitHub: “Mobile and Web client for Codex and Claude Code”)	Claude Code + Codex
Architecture	Desktop/CLI on your machine + remote apps; optional cloud session migration when laptop offline	CLI on your machine + mobile/web clients via a relay that moves encrypted blobs	Local daemon on your machine + clients; E2E encrypted relay (self-host path)
Encryption	Not fully specified on the marketing FAQ — check remote.omnara.com	End-to-end encryption (site + docs: relay cannot read messages/code)	End-to-end encrypted relay; relay forwards ciphertext, not plaintext prompts/diffs
Platforms	Desktop (Mac Apple Silicon + Windows; Linux via CLI), web, iOS, Android, Apple Watch	iOS, Android, web + CLI; self-host docs for own server	Desktop app, mobile, CLI; daemon-centric local-first setup
Voice	Two-way voice + dictation (site FAQ)	Real-time voice / voice coding features (docs)	Voice surfaces in product (see voice docs)
Skills ecosystem	Connects to your existing Claude Code / Codex setup	Terminal-parity Claude Code features on mobile (slash commands, etc., per docs)	Same local agents + Skills Hub install path for agent skills
Open source	Early open-source version (Apache 2.0) is no longer maintained; product of record is remote.omnara.com	MIT open source (github.com/slopus/happy)	Product + monorepo practices — confirm current license on the project you install
Price	100% free, unlimited sessions (per remote FAQ)	Free (“costs nothing” on happy.engineering)	Free app — pay only for model usage (/pricing/)

If a cell says “check their site,” that is intentional: we only lock facts that public pages or public repos state clearly.

Omnara

Omnara Remote is a command center: desktop + web + mobile + Watch for Claude Code and Codex in parallel, with worktrees and Git-oriented desktop tooling. Desktop bundles the CLI on Mac Apple Silicon and Windows; Linux uses the CLI. Public FAQ: free unlimited sessions, two-way voice, Apple Watch, and opt-in cloud session migration when the laptop is offline.

Where Omnara is strong: full workstation surface (not phone-only); optional cloud continuity for opted-in repos; Watch + voice when a permission prompt is the only blocker; free unlimited sessions per FAQ.

Honest limit: cloud migration expands what can leave the machine for opted-in repos — read privacy and sync docs first. Encryption for every hop is not fully specified on the marketing FAQ; verify on their site rather than assuming category defaults. Early open-source Omnara (Apache 2.0) is no longer maintained; evaluate remote.omnara.com as the current product.

Happy

Happy Coder (open source at slopus/happy) is the lightweight community favorite for “Claude Code on my phone without reinventing my workflow.” You install a CLI (happy), start a normal agent session, and continue from iOS, Android, or web. Architecture docs are clear: CLI watches the session, encrypts, sends to a relay; the app renders; the relay moves encrypted blobs.

Where Happy is strong:

• Open source and free. MIT license, public repo, self-host guides — the default pick when you want to read the code and avoid another closed vendor.
• Low workflow friction. Same tools, same terminal culture, phone as a continuation surface.
• E2E encryption narrative is public and simple: relay does not hold readable content.
• Voice and parallel sessions are documented product features.
• Codex + Claude Code — the repo description is “Mobile and Web client for Codex and Claude Code.”

Trade-off: Happy is optimized as a mobile/web client + CLI, not as a full multi-product agent workstation with a skills marketplace and desktop shell of its own. If you need heavy multi-agent orchestration UI, desktop-first tooling, or a skills install hub, you may outgrow “just Happy” — or stay if simplicity is the point.

SeaWork

SeaWork is our product, so here is the fact-shaped pitch only.

SeaWork runs a local daemon on your development machine. Mobile, desktop, and CLI are control surfaces for Claude Code and Codex already on that machine. Traffic over the remote path uses an end-to-end encrypted relay (ciphertext only on the wire; metadata such as connection timing can still exist). Code, provider credentials, and logs stay on your machine unless you deliberately change that model. The desktop app ships with the daemon so bring-up is install → pair → run. Price: free app — pay only for model usage (/pricing/).

Where SeaWork differs: dual-agent control for parallel local sessions; Skills Hub for installing agent skills; desktop + mobile + CLI on the same daemon home; self-host / local-first control path.

Trade-off: SeaWork is another app to install and pair. If you only ever run one Claude Code session and want the smallest OSS client, Happy may be enough. If you want cloud session migration when the laptop dies, Omnara’s opt-in sync may fit better. SeaWork fits when local agents + multi-surface control + skills ecosystem is the job — not when you want a managed cloud agent farm.

Deep dive: Claude Code from your phone and remote control.

Which one should you pick

You are…	Start with
Claude Code-heavy, want free OSS, phone/web continuation	Happy (happy.engineering)
Want desktop + mobile + Watch, parallel agents, optional cloud session handoff	Omnara (remote.omnara.com)
Run Claude Code and Codex, want local daemon + E2E relay + skills hub + desktop	SeaWork (download)
Only need Anthropic first-party path	Anthropic Remote Control (/rc) — not in the title, still valid

Many people try two. That is fine. Cancel the one that sits idle after a billing cycle (or after a month of “free” if both are free — cancel means delete and stop maintaining).

FAQ

Is there a free Claude Code mobile app? Yes. Happy markets itself as free and open source. Omnara’s remote product FAQ states free unlimited sessions. SeaWork is a free app — pay only for model usage (/pricing/). Official Anthropic Remote Control uses the Claude app and Claude account terms. “Free app” never means free model usage: Claude Code and Codex still bill through Anthropic / OpenAI plans or API.

Do these apps see my code? Architecture differs. Happy and SeaWork describe E2E encryption so a relay cannot read prompts, diffs, or code content. Omnara can keep work local and also offers opt-in cloud sync/migration for repos you enable — that path is a deliberate expansion of what can leave the laptop; read their docs. None of these products replace good secrets hygiene: if the agent can read a file on disk, a paired control client that shares the session can show what the agent sees.

Can I use Codex too? Omnara FAQ: Claude Code and Codex. Happy’s public repo: Claude Code and Codex. SeaWork: Claude Code and Codex. Always re-check the product page the week you install — agent support lists move faster than blog posts.

Match the tool to architecture and agent set, not brand heat. Start with the lightest tool that covers the agents you actually run; graduate only when a concrete gap (desktop shell, skills hub, multi-agent, cloud handoff, OSS audit) shows up in real work.
