Span vs. Jellyfish:
The AI-native alternative
Jellyfish relies on planning and delivery metadata. Span connects full agent traces to code, PRs, and outcomes for prompt-to-prod visibility into AI impact and engineering performance. See why modern engineering teams are switching to Span.
Why Span
Built for the way engineering works now
Built for the way engineering works now
Span gives leaders a clearer view of engineering performance and AI impact, without adding more reporting work or requiring every team to follow the same process.
Span gives leaders a clearer view of engineering performance and AI impact, without adding more reporting work or requiring every team to follow the same process.
Prove and improve AI impact
Connect AI usage and spend to shipped work, delivery, rework, and quality. Identify the harness fixes, workflow changes, and developer practices that improve the KPIs that matter.
The right view for every role
Give executives, managers, teams, and ICs the context they need. HRIS-grade permissions keep sensitive individual, survey, and trace data controlled.
Prompt-to-prod visibility
Follow AI-assisted work from the agent session through the code and PR it produced. Understand how the work happened, not only what shipped.
Verify every result
Drill from any metric or finding into the PRs, tickets, code, and agent traces behind it. Span gives leaders evidence they can inspect, verify, and trust.
Flexible by design
Adapt Span to your operating model, metrics, workflows, and culture. Our co-build approach helps teams shape the platform around how they run engineering.
Works without perfect hygiene
Span’s AI inference engine fills gaps when tickets, links, and project structures are incomplete. Get a useful view without forcing more process onto teams.

The Span Advantage
Why teams choose Span over Jellyfish
Why teams choose Span over Jellyfish
01
Built for the AI software factory
Jellyfish was built around planning, allocation, and delivery reporting. Span connects full agent traces to code and outcomes, showing which prompts, workflows, and codebase improvements lead to better results.
04
Faster implementation and results
Customers report getting to value 3–4x faster with Span than traditional platforms. Span starts with your existing systems and reduces the upfront taxonomy, cleanup, and configuration work.
02
Less dependent on process hygiene
Jellyfish relies more heavily on clean Jira or Azure DevOps structures. Span’s AI inference engine fills gaps across code and tickets without adding more tagging or process overhead.
05
Flexible enough to fit your organization
Span’s co-build approach adapts to your metrics, workflows, reporting needs, and rollout model instead of forcing every team into the same framework.
03
Built for more than executive dashboards
Jellyfish was built primarily for executive reporting. Span gives leaders, managers, teams, and ICs tailored views, backed by HRIS-grade permissions.
06
Shows the evidence behind every answer
Move from a metric, classification, or AI finding to the underlying code, PRs, tickets, and agent traces. Understand what changed and why.
