About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Cossistant is a developer-focused support platform providing headless React/Next.js components, real-time messaging, APIs, and backend infrastructure, with customizable AI support agents highlighted in its repository description.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Embed support UI with headless React components

@cossistant/react and @cossistant/next let product teams shape the support interface around their existing application design.

Sources: [2][3]

Use real-time messaging and backend infrastructure together

WebSockets, Hono/tRPC APIs, authentication, Postgres, and Redis form the backend side of the support experience.

Sources: [2][3]

For SaaS teams building a support experience that should match their product

It fits teams that want to control support UI and AI-agent behavior rather than embedding a fixed third-party chat product.

Resolve the license wording discrepancy before use

The LICENSE file is standard AGPL-3.0, while the README adds non-commercial wording and a commercial-license requirement. Confirm the applicable terms with the maintainer.

Supplemental curator note

Cossistant provides more than a chat widget: it includes real-time messaging and backend infrastructure for developer-built support experiences. The README says “AGPL-3.0 for non-commercial use” and asks commercial users to obtain a separate license, while the LICENSE file contains standard AGPL-3.0. Clarify the applicable terms with the maintainer before commercial use or redistribution.
