The closest Jellyfish alternatives are Span for finance reports plus agent traces, DX for surveys, LinearB for PR automation, and Swarmia, Waydev or Weave for published prices. Jellyfish sells by quote; its one public AWS bundle is $30,800 a year for 15 seats.[1][2]
Jellyfish reads Git, Jira or Linear, CI, incident tools and each AI tool's vendor API, and sells AI Impact, Developer Productivity and DevFinOps as modules.[1][3][4] Gartner's first Magic Quadrant for developer productivity insight platforms (2026) named it a Leader, with Atlassian (DX), LinearB and Swarmia.[5][6][7][8]

Facts from each vendor's own pages and AWS Marketplace listings, dated in the sources below; Zest's row is from its own pricing and product.
LinearB runs gitStream rules and AI code reviews on every pull request, next to DORA and AI metrics read from Cursor, Copilot and Claude Code and from Git trailers. Essentials bills at least 50 users and connects GitHub Cloud only; Jira, capitalization and forecasting need Enterprise. Pick it to automate review in a large org.
Swarmia is free for companies with fewer than 10 developers, then sold as modules from $5 a developer a month. It reads Claude Code, Cursor, Copilot and Codex usage per person, prices AI cost at token list price, and posts a daily team summary to Slack or Teams. Data sits in Frankfurt by default. Pick it for a small team on GitHub or GitLab.
DX pairs survey programs (DXI, DevSat) with 80 data connectors and a laptop daemon that marks which lines an agent wrote. Atlassian has owned it since November 2025; it sells after a demo and runs multi-tenant, single-tenant or in your own AWS account. Pick it for surveys next to system metrics, especially if you already buy from Atlassian.
Span records whole agent sessions, as Zest does: a laptop agent, rolled out by MDM, captures Claude Code and Cursor prompts, tool calls and diffs and links them to pull requests. It also covers allocation, capitalization and R&D tax credits, at $45 a contributor a month on a one-year contract. Pick it to keep Jellyfish's finance reports and add agent traces.
Waydev connects GitHub, GitLab, Bitbucket, Azure DevOps and Gerrit, and its Enterprise plan runs in your own VPC, air-gapped if needed. It bills each active contributor: AI adoption from $29 on Pro, AI impact and DORA on Premium at $49, and a free Start Up plan for 10 repositories. Pick it if you are off GitHub or must self-host.
Weave, once Workweave, has a model estimate the expert hours behind each pull request and rolls the scores up per engineer. AI usage comes from tool APIs, git co-authorship and labeled estimates. Starter is free with org-level numbers; Pro is $42 an engineer a month, billed yearly. Pick it if you want one comparable output number per pull request.
Zest is ours. A plugin in Claude Code, Codex, Grok Build or Hermes, or an extension in Cursor or VS Code, uploads each session's prompts, model, tokens, skills and MCP calls; the GitHub App adds the pull request it led to, and each engineer gets a daily standup. Starter is free for 3 seats; paid plans are priced per workspace. No DORA, surveys, capitalization or PR automation, and GitHub only.
Start from what you use Jellyfish for:
TRY IT ON YOUR TEAM
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
Jellyfish doesn't publish prices: its pricing page says the price depends on seats and modules. Its one public AWS Marketplace bundle is the platform with 15 engineering seats for $30,800 a year (checked October 5, 2026).
For a small team, yes: Swarmia is free for companies with fewer than 10 developers, Waydev's Start Up plan and Weave's Starter cost $0 with fewer features, and Zest's Starter is free for 3 seats (checked October 5, 2026).
Its directory lists 60 integrations: GitHub, GitLab, Bitbucket and Azure DevOps, Jira, Linear and Azure Boards, CI and incident tools, and AI tools from Copilot and Cursor to Claude Code and Codex (checked October 5, 2026).
No. Zest measures AI coding (agents, models, skills and sessions) and pull request throughput and cycle time from GitHub; it doesn't ingest deployments or financial data.
