Attio

Attio ranks 510th overall in the SaaS category with a composite score of 38 out of 100. The score summarises how the organization presents itself to developers across GitHub, its documentation, its packages and the wider community.

Its AI and agent readiness and documentation and learning material come across as middling, with room to improve, and are what most developers will notice first when they land on the organization. By contrast, its developer experience and community engagement look minimal today, which is the clearest area where a small amount of focused work would visibly move the needle. Taken together, the picture is of a company whose public developer surface is neither uniformly polished nor uniformly weak, and where different audiences (contributors, integrators, evaluators) will likely form very different first impressions depending on which door they walk through.

Attio maintains 23 public repositories on GitHub, built primarily in TypeScript, JavaScript and Python, which together have collected 92 stars and drawn contributions from 1 developers outside the core team, 17 of those repositories have seen commits in the last 90 days, a useful proxy for how much of the codebase is genuinely alive rather than archived.

For anyone evaluating Attio as a technology choice, weighing a contribution, integrating the APIs, or comparing it against similar companies in the space, the sections below break down each of these signals in detail and link straight through to the underlying repositories, documentation and community threads that inform the score.
