Static snapshot, not a live feed
How this was measured: This report summarises 38 public Reddit threads collected across 8 subreddits through the Reddit API. Thread counts, subreddit shares, the weekly trend, and the date range are computed from those threads alone. Replies have not been collected for this brand yet, so the sentiment split is derived from thread titles and the question each thread asks, which leaves most threads unlabelled; the labels come from a fixed word list, not from human review. This is a sample of public discussion, not a complete or representative measure of it, and not a customer satisfaction score.
Editorial verdict
The collected signal at a glance
Every number below is computed from this brand's own collected threads. The labels come from a fixed word list rather than a human reading each thread, so read them as a sample of public discussion, not a verdict.
Sample verdict
38 public Reddit threads about Mattermost were collected across 8 subreddits, led by r/selfhosted. The dominant question type is alternative shopping (10 of 38), and the highest-scoring thread in the sample is "There is an open-source alternative to almost any SaaS, what do you use?". This report summarises those threads only; it is not a measure of Mattermost's overall standing.
Stance mix: 0% positive · 89% neutral · 11% negative across 38 collected threads, labelled from thread titles alone because replies have not been collected for this brand yet rather than by hand.

Methodology & limitations
A coded sample, not an audited Reddit dataset
The queries and inclusion rules are frozen before the threads are coded, so the sample cannot be tuned toward a more attractive conclusion.
Fixed window
Oct 16, 2015 through Jun 16, 2026.
Automated coding
Threads are deduplicated, classified by the question they ask, and counted. Replies have not been collected for this brand yet, so sentiment comes from thread titles and the question each asks, matched against a fixed word list — not from human review.
Independent QA
No audit is claimed. A second-reviewer pass is added when a page proves traffic or conversion potential.
Known limits
Public, English-language, SFW threads only. Deleted, private, and inaccessible discussions are excluded.
