COMPARE · ZEST VS WEAVE
Sources last reviewed
The closest Weave alternatives are Swarmia and Waydev to price AI use without a score, LinearB for rules on each pull request, and Span or Zest for the session behind it. Weave, once Workweave, scores every pull request with a model; Pro is $42 an engineer a month, billed yearly.[1][2]
Weave reads AI use from tool APIs and git co-authorship, and its model reads each pull request's diff to estimate the hours an expert would need.[3][4][5] Zest's plugin sits in the agent and records the session behind the pull request: model, tokens, skills and MCP calls.

USED BY ENGINEERING TEAMS AT
AT A GLANCE
 Zest | Weave | |
|---|---|---|
| Scores each pull request | No: Zest doesn't score or rank pull requests or engineers. | Yes: A model (Silk 1) estimates the hours an expert engineer would need for each PR; Weave says 88% of its scores land within an hour of an expert's estimate.[1][4] |
| How it reads AI coding | A plugin or extension in each engineer's agent uploads every session: prompts, replies, model, tokens, tools, skills and MCP calls. Cursor's token counts come from Cursor's dashboard, only if the engineer turns that on. | Each tool's API where it has one (Cursor, Copilot), git co-authorship where it doesn't, and activity-window estimates “always labeled as estimated”; per-user cost for Claude Code, Cursor, Windsurf and four other tools.[3] |
| Per-engineer view | Yes: Each engineer's sessions, models, skills and MCP tools, next to their pull requests. | Yes: Pro adds individual and team stats: output, quality and reverts per engineer.[1][2] |
| Answers questions on demand | Yes: Ask Zest answers questions about the team's sessions and pull requests; the MCP server brings them into your agent. | Yes: Wooly, its research agent, answers with sources in the app, in Slack, in your editor or the CLI; an MCP server gives agents the same data.[3][6] |
| Hosting and code access | Cloud only. The plugins upload session transcripts (Claude Code's with file diffs) after redacting secrets on the laptop; the GitHub App never writes to your code. | SaaS on Google Cloud (us-central1) by default; private cloud or on-prem case by case. It reads pull request diffs to score them.[5] |
| Cost for 5 engineers | $49/mo for 5 engineers: one Pro workspace, seats included. | $210/mo for 5 engineers: Pro at $42 an engineer a month, billed yearly ($50 monthly).[2] |
| Free plan or trial | Yes: Starter is free for 3 seats, no credit card. | Yes: Starter is $0, “ideal for basic usage or teams under 5”: output scores, AI ROI and org-level AI, process and quality metrics, with no per-engineer view.[2] |
Facts from each vendor's own pages and AWS Marketplace listings, dated in the sources below. ✓ listed, – partly, × not listed on the pages we read, which is not proof the product lacks it.
workweave.ai redirects to weaveos.com, where the product is called Weave; the app itself still runs at app.workweave.ai. Starter is free, “ideal for basic usage or teams under 5”, with org-level numbers only. Pro adds pull request drill-down, individual and team stats, the Wooly agent and user permissions. Enterprise adds GitHub Enterprise support and custom terms, and private cloud or on-prem hosting is case by case.
Weave tags each AI number verified (from a tool's API), inferred (from git co-authorship) or estimated (from activity windows). It prices usage per person for seven tools, Claude Code and Cursor among them, and per org for the rest. Its model learns from your team's overrides of its scores, and the scores roll up per engineer.
Zest's numbers come from the session itself, model and tokens included. Cursor is the exception: its token counts come from Cursor's usage dashboard, once each engineer turns that on (Cursor usage).
Swarmia reads Claude Code, Cursor, Copilot and Codex usage per person from each vendor's API or OpenTelemetry and prices it at token list price, without grading the work. It is free for companies with fewer than 10 developers, and its AI adoption and cost plan is $5 a developer a month, billed annually.
Waydev compares Copilot, Cursor, Claude Code and Windsurf on cost per commit, per pull request and per feature, on Premium at $49 per active contributor, billed annually; Pro, with AI adoption, is $29. Its Enterprise plan runs self-hosted, where Weave's on-prem option is case by case.
LinearB acts on pull requests: gitStream rules route reviewers, label and approve small changes, and AI reviews comment on each one. Essentials is $29 a user a month, billed annually, for at least 50 users.
Span judges the session behind the pull request: its laptop agent records Claude Code and Cursor traces, and Span runs evals over them and traces each line of a pull request back to the agent that wrote it. It adds capitalization and surveys, at $45 a contributor a month on a one-year contract.
Jellyfish measures delivery across Git, Jira or Linear, CI and incident tools, with AI Impact as one module, and sells by quote; its one public AWS bundle is $30,800 a year for 15 seats. DX pairs survey programs with system data and a laptop daemon that marks AI-written lines. Its AWS listing starts at $15,000 a year.
Zest is ours. It records each engineer's coding-agent sessions (model, tokens, skills, MCP tools) and links them to the pull requests they led to, and scores no one: the team makes the judgment. Where Wooly answers questions on demand, Zest writes each engineer a standup at 6pm; Ask Zest and the Zest MCP server answer questions too. Starter is free for 3 seats. No DORA, capitalization or PR automation, and GitHub only.

Starter is free (3 seats, no credit card). Pro is $49 a month with 5 seats and Max is $149 a month with 10 seats — priced per workspace, not per engineer, with extra seats at $19 a month.
A FEW THINGS TO KNOW
Weave's pricing page lists Starter at $0, Pro at $50 per engineer a month billed monthly or $42 billed yearly, and custom Enterprise pricing (checked October 5, 2026).
Yes. workweave.ai redirects to weaveos.com, where the product is called Weave (checked October 5, 2026).
It depends on whether you want a score per pull request: Swarmia and Waydev measure AI use and cost without grading pull requests, LinearB automates review instead, and Span and Zest record the agent session behind each pull request.
Yes: its trust center lists pull request diffs or selected repository snapshots, with code retention set by the customer, down to none. It runs on Google Cloud in us-central1, and no data is stored outside the US unless negotiated.
