Spendassay vs. DX
DX measures engineering output. Spendassay prices it against spend.
DX is an engineering intelligence platform, and since November 2025 it is an Atlassian product. It measures developer productivity and AI adoption using research-backed frameworks like the DX Core 4 and DevEx, and it is used by large engineering organizations to track delivery and improve how teams work. The frameworks and the product both continue under Atlassian. Spendassay does a different job. It connects every dollar spent on AI (seats, API tokens, infrastructure) to what teams actually ship, and produces a per-dollar AI cost report a CFO can read. Productivity platforms measure output. They do not carry the spend side and price it. Many teams run both.
The one-line difference
DX tells you how much your teams are shipping; Spendassay tells you what each AI dollar bought.
Two jobs, often side by side
Use each for what it's built for
Reach for DX when…
Reach for DX when you want to measure and improve developer productivity and experience across an AI-native SDLC, using established frameworks and benchmarks. It is built for engineering leaders who need a rigorous read on delivery, adoption, and how teams work.
Reach for Spendassay when…
Reach for Spendassay when you need to know whether your AI spend is paying off. It audits the whole AI bill across vendors, ties spend to shipped output with a proof level on every number, and hands finance a forwardable AI cost report. Start free with a Snapshot.
Side by side
Built for different questions
Status update. DX was acquired by Atlassian. The deal closed on 10 November 2025 for about $1 billion, and DX is now part of the Atlassian Software Collection alongside Jira, Bitbucket and Rovo Dev. The brand and the product both continue, and DX Fabric is absorbing Atlassian Compass. What changed for a buyer is that DX is an Atlassian product rather than an independent vendor, so it now sits inside an Atlassian commercial relationship.
| Dimension | DX | Spendassay |
|---|---|---|
| Primary job | Measure and improve developer productivity and experience | Audit AI spend and price it against shipped output |
| What it measures | Delivery, DORA metrics, developer experience, AI adoption | Every AI dollar (seats, tokens, infra) mapped to output |
| Connects spend to shipped output | Built to measure output, not to price the AI bill | Spend priced against output as an AI cost report |
| Independence | An Atlassian product since November 2025, sold inside the Atlassian estate | Independent, cross-vendor auditor of the whole AI bill |
| Evidence on every number | Research-backed frameworks and benchmarks | Each dollar carries a tier (Counted, Compared, Estimated) and shows its formula |
| How you buy | Book a demo; sales-led, now through Atlassian | Self-serve Snapshot, free to start; pricing published |
| Pricing | No public price. Enterprise and sales-led, now through Atlassian. | Published and self-serve: a free Snapshot, then $16 per covered engineer per month (Observe) and $40 (Control). Priced per engineer, never as a percentage of your AI spend. |

Common questions
Spendassay and DX
- Is DX a competitor to Spendassay?
- Not really. DX is an engineering intelligence platform built to measure developer productivity and AI adoption. Spendassay is an independent auditor built to price AI spend against shipped output. They measure adjacent things and overlap on AI adoption, but the core jobs are different. Many teams run both.
- Can I use both?
- Yes, and it is a natural pairing. DX gives you a rigorous read on output and developer experience. Spendassay carries the spend side and ties dollars to that output, so finance sees a per-dollar AI cost report. Spendassay's audit is read-only and metadata-only, and it never writes to your systems.
- Does Spendassay do what DX does?
- No. Spendassay does not benchmark developer productivity or run DevEx surveys, and it never produces individual league tables — it works at the team level. Its job is to audit spend across every AI vendor and connect it to shipped output, with a proof level and a visible formula on every number. For a full productivity program, DX is the right tool.
