Agentic Index

cubic vs Graphite (2026)

Both vendors last verified

Two inexpensive ways into AI review, Cubic's Team at $30 per developer and Graphite's Starter at $20 per user, both billed annually, solving different halves of the pull request problem. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.

Cubic reviews every pull request with whole codebase context, enforces plain English rules and runs background scans that find and fix, free for 20 reviews a month and on public repositories. Graphite restructures the workflow around stacked pull requests with a stack aware merge queue and an agent that reviews, chats, fixes and merges, with a free hobby tier. Cubic makes reviews better, and Graphite makes them smaller, which is arguably the more effective fix.

On the Agentic Index coding agent ranking, neither cubic nor Graphite clears the bar, which asks for all five merge loop capabilities documented in full. cubic does not document observability and auditability in full, nor human oversight and guardrails; Graphite documents two of the five in full. 3 of the 96 vendors in the lane clear it.

This comparison is published by Agentic Index, an independent agentic AI vendor research platform. cubic and Graphite are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 1,084 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded

Choose cubic if

  • Review quality is the immediate need, and you want rules your team writes in plain English.
  • Plain English rules are how your team will keep conventions current.
  • Background scanning outside the pull request finds what review never sees.

Choose Graphite if

  • Your pull requests are too big to review properly and stacking is the structural answer.
  • A merge queue that understands stacks removes a real source of friction.
  • You want the workflow fixed, not just better commentary on it.

Action & orchestration

Integrations & Tool Calling

Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools.

Workflow Orchestration

Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps.

Triggers & Channel Coverage

How agents wake up and where they work: schedules, webhooks, message events, CRM events, inbox events, chat, email, voice, and collaboration tools.

Knowledge & context

Knowledge Grounding & RAG

Ability to ground agent behavior in company data through document ingestion, retrieval, external knowledge APIs, semantic search, or RAG layers.

Memory & State Persistence

Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer.

Control & trust

Human Oversight & Guardrails

Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls.

Security, Identity & Governance

RBAC, SSO, auditability, encryption, least-privilege tool access, compliance posture, and data handling policy.

Observability & Auditability

Traces, logs, execution histories, metrics, audit events, and debugging detail for production agent behavior.

  • · Agent capability

    Codebase scan agents in cubic can now check whether production data confirms the bugs and vulnerabilities they find, starting with PostHog, which is switched on per repository under Production evidence.

    Source
  • · Human approval / guardrails

    cubic added a repository policy that allows automatic pull request approval while findings at selected priorities remain unresolved.

    Source
  • · Agent capability

    cubic now supports cross-repo reviews, allowing users to link up to five related repositories for coordinated updates.

Graphite joined Cursor after a December 2025 agreement with Anysphere, the maker of Cursor, and Anysphere became a SpaceXAI division in August 2026, so Graphite is not an independent vendor.
