Compare
Arrio vs Swarmia
Swarmia and Arrio both put software development into numbers, and they point in opposite directions. Swarmia points inward, giving teams visibility into their own effectiveness. Arrio points from outside in, giving the budget owner an independent read. Here is how they compare.
Swarmia
Engineering effectiveness, owned by the teams.
An engineering effectiveness platform for engineering organisations of any size. It covers business outcomes, developer productivity and developer experience, tracks DORA and SPACE metrics, and detects pull requests assisted by AI coding tools. Notably, it is built for developers and teams to use themselves, not only for managers to report on them.
Arrio
Independent measurement, from the outside.
An independent read of what the software investment produces, for the people who fund it. It reads the work itself from the codebases, grounds it in cost, and reports to the CEO, CFO and CIO in business terms, including whether the AI investment is paying off. Built to govern the spend.
Side by side
Where they differ
| Swarmia | Arrio | |
|---|---|---|
| Who it is built for | Engineering leaders, managers and the developers themselves, working on their own effectiveness. | The budget owner. CEOs, CFOs and CIOs who fund software and answer for the return. |
| Direction of the measure | Inward and self-directed. Teams see their own data and act on it, which is what makes it adopted rather than resented. | Outward and independent. An outside party reads the work and reports to the people funding it. |
| What it measures | DORA and SPACE metrics, initiative progress, developer experience, and AI-assisted pull requests. | What the investment produces: output and value across teams and vendors, set against cost. |
| Where the data comes from | Integrations with source hosting, issue trackers and chat. | The work itself, read from the codebases, plus cost. Not dependent on how diligently tickets are kept. |
| Relationship to the teams measured | Adopted and run by the engineering organisation, by design. | An independent outside read, with no stake in how the number looks. |
| Commercial model | Per-developer subscription, with a free tier for small teams. | Not published. Speak to us about pricing and services. |

It is not either / or
Teams should own their improvement. Boards should not own it too.
Swarmia’s design choice is a good one: metrics that teams use themselves get adopted, while metrics imposed for reporting get gamed. That is exactly why it is the wrong instrument for governing an investment. A measure teams own is a measure teams shape. For improving how a team works, that is a feature. For telling a board what the money produced, it is the reason an independent reading has to come from somewhere else. Understand the wider picture in measuring software development.
What is the difference between Arrio and Swarmia?
Swarmia gives engineering teams visibility into their own effectiveness, spanning business outcomes, productivity and developer experience, and it is designed for the teams themselves to use. Arrio gives the people who fund software an independent read of what it produced. One is owned by the organisation being measured; the other is deliberately not.
Why does it matter who owns the measure?
For improvement, team ownership is the right answer and Swarmia is right to build for it. For governance it is the problem. When the people whose budget is under review also configure, run and interpret the measurement, the result is management information rather than assurance. That is not a comment on anyone’s integrity, it is why auditors are external.
Swarmia detects AI-assisted pull requests. Does Arrio do that?
Arrio measures the AI-built share of the work too, and then asks the question that follows: whether that work is producing value. Detecting which pull requests were AI-assisted tells you adoption. Setting that against what the work delivered, in cost terms, tells leadership whether the AI investment is paying off.
Can we use both?
Yes. Swarmia helps your teams get better at how they work. Arrio tells the people funding them what that work produced. They serve different people and neither substitutes for the other.
