Where it sits in the data

Yaak – The local-first API client's $5.3K MRR is higher than 90% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Dev Tools” category (717 projects) it is higher than 93% (category median $100). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view is that this needs real work. The buyer is a developer or team that sends API requests, debugs APIs, and collaborates through Git. Demand would come from people working across several API formats who want a desktop client with request reuse and Git-based sharing.

Distribution would have to come from developer communities, API-related content, integrations, and direct product discovery. Supporting several operating systems and API formats is one challenge. Plugin support, Git workflows, compatibility, and ongoing technical support add more work, while competing API clients are another consideration.

Verdict: Needs real work.

One thing to take from it

My view is that the product's appeal comes from putting API requests, debugging, reusable values, Git collaboration, plugins, and agent connectivity inside one desktop client. The buyer and the product workflows are both specific.
