podium

Zed
vs Delta

A source-linked comparison across the complete Podium ADE rubric. 5 criteria have sourced findings for both products; 5 were also cross-checked by a second agent for both. 14 rows have at least one sourced finding, including 14 with an agent-cross-checked finding. No score or winner is inferred.

Each finding carries its own verification status, scope and dates. Humans approve the rubric, templates and prototype; they do not review every finding. An agent source cross-check is not a hands-on product test. 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.

ACC-04

Onboarding and project prerequisites

Judgment rule. Measure fresh install to first successful task, with manual steps and failures. Test a local directory without Git, a local Git repo without a remote, and a GitHub-backed repo separately. Record whether account, project, host, credential and permission prerequisites are explained before accepting an unusable prompt. Evaluate managed-cloud setup and first-class BYO VPS installer/onboarding independently of hidden settings or a DIY shell recipe.

No publishable sourced finding is available for this criterion. This does not mean the product lacks the capability.

ACC-05

Programmable access

Judgment rule. Inventory actual CLI, API, SDK, MCP and webhook operations for create, inspect, steer, stop and review. Record authentication and API stability. Having an MCP client that uses external tools is different from exposing the product to other agents over MCP.

Client implementation

Judgment rule. For each desktop/mobile client, record native platform UI, Electron, Tauri, React Native, web/PWA or unknown, plus hybrids. Require official technical docs or pinned source/build evidence. Tauri is not synonymous with fully native UI. Keep implementation choice separate from measured responsiveness and usability.

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.

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.

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.

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.

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.

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.

Coordination and automation

COORD-01

Parallel work

Judgment rule. Record independently running sessions and tasks, documented quotas and observed concurrency. Describe how a user sees running, waiting, failed and finished work. Several chat tabs are not proof that runs execute concurrently.

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.

RUN-02

Workspace and process isolation

Judgment rule. Record shared checkout, branch, worktree, container, VM and OS sandbox separately. Name filesystem, process, network and secret boundaries. Validate code separation with two changes; do not claim hostile-code containment without separate security evidence.

Recovery, expiry and continuity

Judgment rule. Test client disconnect, worker crash, service restart and documented sandbox expiry safely. Separate transcript reload, process reconnection, task resumption and state reconstruction. Record lost context, duplicated actions, manual repair and ability to continue a multi-day epic after compute replacement. Short sandbox lifetimes are reported with their continuity behavior, not automatically treated as failure.

Truthful status and operational statistics

Judgment rule. Record logs, traces, failure reasons, usage exports and statistics by task, agent, project and time. Induce a worker failure and an approval wait: check agent, task and board state agree and remain correct after reconnect. Distinguish working, blocked, failed, idle, ready for review and delivered. For speed/success claims disclose fixture, model, hardware, attempts and failures. UI responsiveness needs observed interaction timings; never infer a framework from lag.

Queue multiple browser end-to-end tests under a declared safe capacity; verify excess work queues or throttles rather than overloading the host. Inspect cancellation, fairness, recovery and whether overlapping epics share limits. Do not run an uncontrolled load test.

Verification and delivery

SHIP-01

Retained artifacts and outputs

Judgment rule. Record diffs, documents, screenshots, recordings, previews and test/reviewer outputs. Check for a searchable/browsable artifact gallery or equivalent retrieval, linked to task and exact revision, usable after sessions end. Reopen a completed child reviewer and retrieve its full findings. Check whether internal prompts or tool metadata unintentionally appear in the produced application or other user-facing output. In-chat attachments, persistent review evidence and a cross-task gallery get distinct answers.

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.
