What we can tell you now
One-time/free ownership path documented
perpetual-license ownership
Is this a recurring subscription or an owned purchase?
Purchase model: free/open-source. Current recorded recurring price: $0. Free/baseline path: Full browser available without subscription.
Evidence confidence: 99% · checked 2026-08-28LessBother signal
- Ownership-positive on licensing. The evidence shows a non-recurring ownership/free path for the product or legacy license described here. Check the exact current product name because software licensing can change.
This signal applies only to the verified ownership question above. It is deliberately narrower than a full verdict.
Why this matters
- Software ownership can change underneath a familiar product name. This evidence distinguishes a perpetual/free path from a recurring subscription or a legacy product that has been replaced.
What would make us change this answer?
- We would change this answer if the vendor changes the purchase/subscription model, retires the current plan, or replaces the product with a materially different licensing path.
Additional ownership evidence
These findings are separate from the lead buyer answer. LessBother shows the applicability level on every item so broader family/platform evidence cannot masquerade as exact-model proof.

Confirmed on this exact product: perpetual-license ownership, software ownership/licensing.
LessBother has not yet published an exact-product finding here on:
- data/privacy policy
- export/exit path and lock-in
Those are research gaps, not negative findings. We leave them blank until there is evidence.
What this page does not claim
LessBother has evidence for the question above. That is not the same as declaring this product the best or worst overall. We would rather give you a narrow answer we can prove than pad the page with generic review filler.
LessBother record history
This is our revision trail. Corrections and future conclusion changes belong here instead of silently replacing the old answer.
- Record established
Initial public LessBother exact-product record established from primary-source evidence already in the research database.
- Evidence updated
v129 added separately scoped primary-source ownership evidence to this existing buyer-answer record. Broader platform/family context remains labeled as broader than the exact product.
Evidence behind the answer
Each claim below is tied to the primary source stored in the LessBother research record.
