# Google Antigravity vs Proliferate

> 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 4 criteria with sourced findings for both products, including 4 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.

### 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.

### ACC-07: 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.

#### Google Antigravity

### 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.

Support: not-published

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

### 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.

## 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.

## 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.

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

### OWN-07: Enterprise assurance

Judgment rule: Record each claimed assurance separately: ISO standard/certificate scope, issuer and validity; SOC 2 report type, covered service and audit period; report/certificate access and verification date. Distinguish public documentation, vendor assertion, independently accessible evidence and unavailable evidence. A logo, enterprise pricing tier, SSO or a provider certification does not prove this product is certified or audited. Report controls in TEAM-02 separately; no legal-compliance verdict.

### OWN-08: Useful free tier and evaluation access

Judgment rule: Distinguish an ongoing free tier, time-limited trial, credits-only trial, open-source self-hosting costs, paid-only access and gated early access. Map which shared scenarios work for free, especially two-person collaboration, BYO subscriptions, remote compute, mobile, issue management and review. Record card requirement, usage caps and whether meaningful evaluation needs payment or sales approval.

### 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.
