# Amp vs cmux

> Podium publishes this catalog and sells an agent development environment. Podium chooses the products, criteria, sources and wording, so treat these pages as vendor-authored research. Check important claims against the linked primary sources. The same evidence rules apply to Podium and its competitors, but they do not remove this conflict of interest.

This comparison has 3 criteria with sourced findings for both products, including 3 that a second agent cross-checked for both. 14 criteria have a sourced finding for at least one product. "Sourced" findings passed publication validation. "Agent cross-checked" findings also received a separate agent source pass, not necessarily a hands-on test. Humans approve the rubric, templates and prototype; they do not review every finding. It does not declare a winner. A missing sourced finding is not evidence that a capability is absent.

## Access and agent choice

### ACC-01: Client access

Judgment rule: List desktop OS and minimum versions, iOS, Android, browser, mobile browser, CLI and editor extensions separately. For each client, record start, steer, approve, review and resume actions, notifications and plan restrictions. Test moving the same task from desktop to phone; distinguish an installable mobile app from a mobile website and from status-only monitoring.

## Planning and context

### PLAN-01: Intake and external tracker relationship

Judgment rule: Record local creation, prompt intake, issue import and chat/Git triggers. Identify the authoritative tracker, stable issue IDs, one-way or two-way sync, supported edits and operations requiring a trip back to Linear/GitHub/Jira. Importing or attaching a ticket is not native issue management. Answer PLAN-06 and PLAN-07 separately.

### PLAN-02: Durable task plans

Judgment rule: Record task plans and acceptance criteria, editors, revision history and links to implementation. Test amending a task while work is running, restarting and revisiting it later. A task-specific starting brief, reusable memory and a persistent product specification are different objects; product specs are judged in PLAN-08.

### PLAN-03: Hierarchy, dependencies and evolving scope

Judgment rule: Record epics, arbitrary parent/child depth, blockers, readiness, dependency enforcement and state propagation. Start with a simple interactive task, grow it into an epic and retain its identity, discussion, history and outputs. Verify blockers actually prevent dispatch. Record whether a rigid preselected workflow is required, and whether changing scope requires recreating work.

### PLAN-04: Shared context and memory

Judgment rule: List repository instructions, skills, project docs and cross-session/cross-harness memory. Record scope, provenance, citation, correction/deletion and stale-context controls. Test what survives a new session or colleague takeover. A notes page or shared file is not automatically a maintained spec or managed memory.

### PLAN-05: Architecture and API awareness

Judgment rule: Record code search, repository indexing, external knowledge and multimodal inputs, with source freshness and access scope. Ask an agent to use an existing API under a documented architecture rule, then propose a conflicting change. Check retrieval, citation, conflict detection and review-time enforcement separately. A large context window or an instruction file alone does not prove architectural consistency.

### PLAN-06: Native issue management and idea backlog

Judgment rule: Enumerate create, edit, discuss, prioritize, label, assign, search, filter, archive, reopen and project/epic views within the product. Save an idea without creating a running agent, refine it with another person, and explicitly mark it ready or dispatch it later. Record separate task/session entities, metadata depth, multiple sessions per task, durable state transitions and whether an external tracker remains necessary.

### PLAN-07: Agent-native issue operations

Judgment rule: Verify an agent can read/create/update the same durable issue IDs and fields humans use, claim/assign work, change state, create dependencies/children and report blockers/results through documented CLI/API/MCP. Check that human views reflect actual writes with attribution, permissions and conflict handling. Distinguish shared authoritative records, synchronized external records, agent-private metadata and prompt-only conventions.

### PLAN-08: Living product specifications

Judgment rule: Record persistent requirements across tasks/releases, editable by humans and agents with attributable revisions and approval rules. Verify requirement-to-task/implementation links, retrieval during later tasks, drift detection and consideration during review/quality control. Amend a requirement after one task ships, then implement another. A one-time spec-to-plan workflow, per-task brief, memory store or unreferenced document does not establish a living product spec.

### COORD-03: Inspectable delegation and communication

Judgment rule: Record parent/child roles, model/harness/effort choice, messages, result return and cross-harness teams. Distinguish product orchestration, provider-native subagents, installed orchestration skills and scripts. Record activation, auth and experimental flags. Verify actual child identity, live progress, retained results and ability to reopen or follow up after completion. A final sentence claiming two reviewers ran is not proof. Test the documented invocation as well as the shared natural-language request.

### COORD-05: Intervention and attention

Judgment rule: Record pause, stop, resume, steering, notifications, pending decisions and escalation. Test an in-run amendment and a harmless approval prompt in both chat and terminal modes. Record silent waits, hidden CLI-only questions and whether stop terminates execution while preserving history. Require discoverable errors rather than inferring success from silence.

### COORD-06: Fleet and epic management UI

Judgment rule: Use a disclosed fixture of 12 task/agent states across several epics, including blocked, failed, awaiting input, reviewing and completed work. Locate parent/child relationships, dependencies, attention needs, history and workload without reading every transcript. Record navigation steps and errors. Boards, graphs, waterfalls, timelines or another interface can qualify; no required visual form. State whether the fixture was simulated or used live agents.

Judgment rule: Compare a quick interactive change with a growing epic. Record mandatory workflow/preset selection, natural-language configuration, per-agent model/effort control, changes during execution and whether the UI exposes what actually ran. Test a coordinator with two reviewer children; capture roles, relationships and results during work and after completion. Document discoverability and auth friction without judging an unsupported magic prompt as proof of missing capability.

## Execution and reliability

### RUN-01: Laptop-independent execution

Judgment rule: List local, user-owned VPS/remote host, self-hosted service, vendor cloud and hybrid modes. Record provisioning, payer, compute resources, region, idle/max lifetime and disconnection rules. Close/disconnect the originating client and continue from another device. A hosted UI or keep-awake setting is not evidence of remote execution. Record managed-cloud convenience separately from BYO setup effort in ACC-04.

### OWN-09: Pricing transparency

Judgment rule: Record publicly stated units, included limits, overage rates, compute/model pass-through or markup, minimum commitment, cancellation and sales-only unknowns. Use transparent, partially specified, quote-only or unknown, with named missing fields. A quote-only enterprise price is a disclosed procurement constraint, not proof of dishonesty.
