Spendassay vs. Faros AI
Faros AI measures how engineering runs. Spendassay audits what the AI bill bought.
Faros AI is an engineering-intelligence platform. It pulls data from the software delivery lifecycle across a wide set of integrations and reports delivery metrics, DORA, AI adoption, and developer experience for engineering leaders. Some of that view now includes AI context, such as adoption of AI coding tools and their effect on delivery. Spendassay does a narrower and different job. It audits the entire AI bill across vendors, including seats, API tokens, and infra, and prices each dollar against the output teams shipped, with a proof level and a visible formula on every number. One is built to improve how engineering runs; the other is built to make AI spend defensible to finance.
The one-line difference
Faros measures engineering output and shows AI adoption; Spendassay independently audits the whole AI bill and prices it against that output.
Two jobs, often side by side
Use each for what it's built for
Reach for Faros AI when…
Reach for Faros when engineering leadership needs a broad operational view of delivery, DORA, and AI adoption across many SDLC tools, and wants to improve how the org ships.
Reach for Spendassay when…
Reach for Spendassay when finance or engineering needs an independent, cross-vendor audit of AI spend priced against shipped output, in a form a CFO can forward.
Side by side
Built for different questions
| Dimension | Faros AI | Spendassay |
|---|---|---|
| Primary job | Measure and improve engineering performance across the delivery lifecycle | Audit AI spend and price every dollar against the output teams shipped |
| What it measures | Delivery, DORA, AI adoption, and developer experience, with a view into AI tool usage | The whole AI bill across vendors (seats, API tokens, infra), tied to shipped work |
| Independence | Engineering-intelligence platform for eng leaders, spanning many SDLC integrations | Independent auditor of the whole AI bill, tied to no vendor's scoreboard |
| Evidence on every number | Metrics aggregated across connected tools | Each dollar carries a tier (counted, compared, or estimated) and exposes its formula |
| What you hand a CFO | Engineering dashboards and reports for leadership | An AI cost report that prices spend against output, forwardable as-is |
| How you buy | Book-a-demo; pricing is contact-sales | Free self-serve Snapshot; published pricing from Observe at $16 per engineer per month |
| Pricing | A free open-source community edition, self-hosted and unsupported, plus a commercial platform priced per contributor with enterprise quoted. Check faros.ai/pricing for the current rate. | 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 Faros AI
- Is Faros AI a competitor to Spendassay?
- They overlap at one edge and diverge everywhere else. Faros is an engineering-intelligence platform that measures delivery and AI adoption for engineering leaders. Spendassay does one job: independently audit the whole AI bill across vendors and price it against shipped output, with a proof level on every dollar. Many teams run a productivity platform and a spend audit side by side.
- Can I use both?
- Yes, and it is a common setup. Faros tells you how engineering is performing across the delivery lifecycle. Spendassay tells you what the AI spend behind that work returned, priced with visible formulas and proof levels. The two answer different questions.
- Does Spendassay do what Faros does?
- No. Spendassay does not report DORA, cycle time, or broad SDLC delivery metrics, and it never ranks engineers. It reports at the team level and stays read-only and metadata-only. Its job is to connect AI spend to shipped output and produce a CFO-credible AI cost report, not to measure overall engineering performance.
