Superterm

Superterm is a session-aware tmux dashboard for managing parallel AI coding agents — free for personal use, $25/month commercial — built by OpenFaaS founder Alex Ellis, with sparklines, status detection, mobile access, and a logbook.

Key takeaways

  • Now free for personal and open-source use (March 2026); commercial use is $25/month — a major shift from the original $250/year paywall
  • Built by Alex Ellis, founder of OpenFaaS — the 'unknown team' question is resolved; it's a commercially supported OpenFaaS Ltd product
  • Session-aware dashboard over tmux — sparklines, status orbs, bell detection, and a weekly heatmap across every agent session, with mobile/PWA access

Executive Summary

Superterm is a tmux dashboard that solves the problem of running many AI coding agents and losing track of which ones need attention.[1] It wraps tmux with sparklines, status orbs, bell detection, a weekly heatmap, a logbook for intent tracking, and mobile access via PWA. Unlike native Mac apps, it's designed to run on any machine, including headless Linux servers.

Status update (June 2026): Superterm is alive and actively developed. Two material facts changed since the March 2026 profile: the maker went public — it's built by Alex Ellis, founder of OpenFaaS, under OpenFaaS Ltd[2] — and pricing flipped from $250/year with no free tier to free for personal/open-source use with commercial licenses at $25/month, or about $20/month billed annually (the free tier was announced March 20, 2026).[3]

Product Overview

Superterm sits on top of tmux and provides a browser-based dashboard for monitoring agent sessions.[1] It detects agent status (working, waiting, errored, finished) via native hooks for Claude Code, Codex, Gemini CLI, Amp, OpenCode, and Aider, or via custom superterm notify commands for shell scripts. Sessions can be launched from Superterm itself or from any terminal emulator (VS Code, Zed, Ghostty) and then monitored from the web or a phone.

The Logbook feature anchors goals to each session with Now/This Week/Horizon layers, so you don't lose track of what each agent is supposed to be doing when context-switching.

Technical Architecture

Superterm is a CLI binary that wraps tmux and serves a web dashboard.[5] Sessions run in tmux, so they persist independently of the superterm process.

Key Technical Details

AspectDetail
DeploymentCLI binary + web dashboard (any machine with tmux); installed via arkade from a container image[5]
Runtimetmux 3.0+; Linux, macOS, Windows (WSL2)
Model(s)None — agent-agnostic
IntegrationsClaude Code, Codex, Gemini CLI, Amp, OpenCode, Aider (native hooks), any CLI via superterm notify
Open SourceNo — proprietary; free Community Edition for personal/open-source use[2]

Strengths

  • Headless Linux focus — Run agents on a $300 mini PC or €37/mo Hetzner server instead of a $3,900 MacBook; unique positioning in the category[1]
  • Mobile access — Check and unblock agents from your phone; few competitors offer this
  • Logbook for intent — Track what each agent is working toward with Now/This Week/Horizon; solves the "what was this agent doing?" problem
  • tmux independence — Sessions survive superterm restarts; no lock-in to the dashboard process
  • Agent-agnostic — Works with any CLI agent plus shell scripts via superterm notify
  • Known, credible maintainer — Built by Alex Ellis (OpenFaaS), with a stated commitment to commercial support and long-term development[2]
  • Free for personal use — The Community Edition (March 2026) removes the cost barrier for individuals[3]

Cautions

  • Commercial use requires a paid license — $25/month for any work-related use, with a strict EULA: a single 30-day evaluation per person, no repeat trials[2]
  • Not open source — Proprietary; can't inspect or modify the code, and the Community Edition license is "revocable"[2]
  • Minimal public traction — The March 2026 "free for personal use" Hacker News post drew 2 points and 1 comment; there's little independent discussion or review coverage as of June 2026[3]
  • Browser-based — No native app; some developers may find the PWA approach less polished
  • No worktree management — Dashboard only; doesn't manage git worktrees, branches, or merges

What Developers Say

As of June 2026, there is essentially no independent community discussion of Superterm to quote. The product's only Hacker News appearance — "Superterm.dev is now free for personal use" (March 20, 2026) — drew 2 points and 1 comment,[3] and no substantive Reddit threads or third-party reviews surfaced in searches. The most visible commentary comes from the creator himself, Alex Ellis, who pitches it as managing agents "the way it was meant to be" and highlights the agent-pause feature as fixing his "biggest bug bear" — broken copy/paste — with these tools.[4] Treat the lack of user testimony as a data point: adoption appears early and small.


Pricing & Licensing

TierPriceIncludes
Community EditionFreePersonal, hobby, educational, and open-source use only
Professional$25/month ($60 savings annually)Commercial and team use; covers all your devices

Licensing model: Per-person subscription (not per-machine). Commercial use — anything connected to a job, client, employer, or organization — requires a paid license. One 30-day evaluation period per person; no repeat trials.[2]

Hidden costs: Agent CLI subscriptions are separate. Server costs if running on cloud.


Competitive Positioning

Direct Competitors

CompetitorDifferentiation
cmuxNative macOS terminal with notifications — superterm is browser-based, cross-platform, headless-friendly
dmuxtmux-based multiplexer with worktrees — superterm is monitoring/dashboard, not orchestration
EmdashGUI dashboard with issue trackers — superterm is lighter, works on headless servers
TemboFull orchestration platform — superterm is individual monitoring layer

When to Choose Superterm Over Alternatives

  • Choose Superterm when: You run agents on headless Linux servers and need mobile monitoring
  • Choose cmux when: You want a native macOS terminal with notification rings
  • Choose Emdash when: You want issue tracker integration and GUI-based agent management

Ideal Customer Profile

Best fit:

  • Developers running agents on headless Linux servers or cloud VMs
  • Anyone wanting to monitor agents from mobile/tablet
  • Power users running 10+ parallel agent sessions who need a status overview

Poor fit:

  • Developers who only work from a Mac and prefer native apps
  • Commercial teams unwilling to pay $25/month/person when open-source alternatives exist
  • Teams needing orchestration, not just monitoring

Viability Assessment

FactorAssessment
Financial HealthBootstrapped under OpenFaaS Ltd — an established indie software company with a track record of commercially supporting products[2]
Market PositionNiche — headless Linux + mobile monitoring; differentiated but early
Innovation PaceActive — pricing overhaul, Gemini CLI/Aider hooks, weekly heatmap, privacy mode, and built-in tmux tutorial all shipped since March 2026
Community/EcosystemMinimal — near-zero independent discussion as of June 2026[3]
Long-term OutlookModerate — credible maintainer and active development, but adoption is unproven

Bottom Line

Superterm carves out a unique niche: the developer who runs agents on cheap headless Linux hardware and monitors from a phone. The headless Linux pitch is genuinely differentiated — most competitors assume you're on a MacBook. Two of the March 2026 concerns have resolved favorably: the maker is now public (Alex Ellis of OpenFaaS, a credible indie maintainer) and personal use is free.[3] What hasn't resolved is adoption — there's almost no independent community discussion, and the product remains closed source with a strict commercial EULA.

Recommended for: Developers running agents on headless servers who need mobile monitoring — especially individuals, now that personal use is free.

Not recommended for: Mac-centric developers, anyone wanting open-source tooling, or commercial teams not ready to pay $25/month/person.

Outlook: Stronger than three months ago. A known maintainer, active development, and a free personal tier address the sustainability and cost objections; the open question is whether the niche is big enough to build a community around.
