Positron Flux vs Jellyfish
Both platforms track engineering metrics. Flux is built to close the loop: understand why they moved, and prove what fixes them.
How they compare
| Positron Flux | Jellyfish | |
|---|---|---|
| Delivery metrics | Deployment frequency, lead time, change failure rate, MTTR. Benchmark bands for context. | Same four metrics, plus SPACE. Industry benchmarks from 20M+ PRs. |
| Root cause analysis | Correlation engine auto-surfaces what changed when a metric moves. Evidence, not guesswork. | Data Hub (2026) offers bottleneck and correlation analysis. Requires manual exploration. |
| Improvement workflow | Structured experiments: set a hypothesis, run it, read the result with statistics. Research-grounded playbooks. | AI-generated recommendations. No experiment framework. No playbooks. |
| In-workflow tools | Platform bots in Slack, GitHub, and Jira that nudge better practices where your team already works. | Slack alerts for aging PRs and review bottlenecks. No interactive GitHub coaching. |
| AI impact | Measures whether AI tools are actually improving delivery outcomes. | Tracks AI spend, multi-tool comparison, and adoption trends. Strong on cost visibility. |
| Developer surveys | Roadmap | Research-backed DevEx surveys with validated methodology. |
| R&D capitalization | — | SOC 1 Type II audit-ready financial reports. |
| Pricing | Accessible. Early Access Program with founder-led onboarding. | Enterprise sales only. $30K–$150K+/year. Months-long implementation. |
| Best for | Teams of 5–200 engineers who want to understand and improve delivery, not just measure it. | Large enterprises (500+ engineers) with dedicated platform teams and budget for financial compliance. |
Which is right for you?
Positron Flux
- You want to know why a metric moved, not just that it did. The correlation engine surfaces the answer automatically.
- You want to prove what works with structured experiments and research-grounded playbooks — not just read dashboards.
- You want bots that nudge better habits in Slack, GitHub, and Jira — without surveilling individuals.
- You're a team of 5–200 engineers who want one-click setup and direct founder access.
Jellyfish
- You're a large enterprise needing SOC 1 Type II financial compliance and audit-ready capitalization reports.
- You need industry benchmarks built on 20M+ PRs across 1,000+ organizations.
- Your primary use case is executive reporting and investment allocation, not team-level improvement.
- You have a $100K+ budget and a platform team for a months-long implementation.
