Why people look

Usually one of three reasons: the price stopped making sense, the free tier disappeared, or the tool does one thing well and everything else badly. All three are visible in the table below without reading a review.

How to choose

Start from the constraint, not the feature list. If you need a free tier to evaluate, that removes half the table immediately. If you are replacing a subscription you already pay for, compare the entry price rather than the enterprise tier you will never buy. Everything below is checked weekly and dated.
