Best Browser Extensions software for Startups in 2026

How this ranking is derived
The sort key
Published rating, highest first. Ties break on the number of ratings behind the score, then on product name so the order never depends on what the API happened to return first. That is the whole rule, there is no weighting, no score of our own, and nothing paid: no sponsored slot runs on these pages.
Where the ratings come from
No listing in this set carries a rating, so the order falls back to name. Those scores are aggregated from public sources rather than collected here, Softwr hosts no reviews of its own, which is also why no rating on this page is marked up as ours in structured data.
What the pool is
Approved browser extensions listings, capped at 20 per page; 20 came back for this one. It is not the whole market, and a tool being absent means we hold no record of it rather than that it failed a test. The unranked full set is on the browser extensions category page.

What browser extensions software costs
Counted from the published pricing of the 20 listings on this page. A tool counts as free only where it publishes a $0 plan, an open-source licence or a starting price of zero.
- Cheapest paid plan
- $1.79Keeper
- Median entry price
- $8.33across 3 priced
- Dearest entry price
- $9Night Eye
- Publish a $0 plan
- 12of 20
Paid browser extensions plans in this set start anywhere from $1.79 a month for Keeper to $9 for Night Eye. The median entry price across the 3 tools that publish one is $8.33, half of them start below that figure and half above it.
Entry price is not the ceiling. The dearest published tier anywhere in this category is Night Eye's at $40 a month, 4.4× the highest entry price on the page. Read the top of each ladder as well as the bottom, because that is where you land after two years of growth.
12 of 20 publish a $0 plan, and 9 of those charge nothing at all.
1 of 20 keep at least one tier unpriced and sold by quote, which in practice means the number you end up paying at the top end is not on this page or on theirs.
How these vendors bill
The billing model each of the 20 browser extensions listings publishes, counted. Two tools at the same headline price are not the same purchase if one of them charges per seat.
- free
- 5
- freemium
- 3
Separately, 1 of 20 publish at least one tier with no price attached. Those are sold by quote, so the top of the ladder is negotiable, and unknowable, until you talk to sales.

How to choose between them
Four things the numbers above should change about your shortlist.
Start with the free tiers if there are enough of them
12 of 20 browser extensions tools here publish a $0 plan, which is enough to run a real trial without a purchase order. A free tier is worth more than a free trial when you are evaluating: a trial expires on the vendor's schedule, a free plan expires when you outgrow it. The thing to check before you commit is which of the capabilities below sit above the free line, starting with basic annotation, the single most frequently named capability in this category's published tiers.
Read the spread before you read the features
$1.79 to $9 is a $7.21 spread on entry price alone, and a spread that wide is never about polish, it is about who the vendor built for. Tools at the bottom of this ladder are priced for one person or a small team; tools near $9 are priced for a department with a procurement process. Decide which of those you are before you compare capability, or you will shortlist four tools that were never competing for the same buyer.
Check which tier you actually land on
3 of 20 tools here publish three or more tiers, and the median vendor in this category ships 1 of them. The advertised price is the first rung, and the things teams tend to need, basic annotation, full page capture, are named in higher plans far more often than in entry ones. Price your shortlist at the tier that contains what you need, not at the tier on the pricing page's left edge.
The billing model matters more than the headline number
This category splits across 2 billing models: free on 5 listings, freemium on 3, and nothing else. A per-user price and a flat subscription at the same headline figure are not the same purchase, the first one grows with headcount and the second does not. Multiply by your real team size before you compare two numbers side by side.
Questions people ask about browser extensions software
Answered from the listings on this page, and nowhere else.
- How is this browser extensions ranking decided?
- Mechanically. The 20 approved browser extensions listings on this page are sorted by their published rating, highest first, with the number of ratings behind each score as the tie-break and the product name as a final tie-break so the order is stable. Those ratings are aggregated from public sources, not collected from Softwr readers, this site hosts no reviews, so the order is a summary of what is already published elsewhere, not a verdict of our own. Nothing on this page is paid placement.
- Is this list re-ordered for startups?
- No, and it would be dishonest to imply otherwise. The catalogue records no data about which team sizes or roles each tool suits, so the ranking is the same published-rating order as the unsegmented list. What the startups framing changes is which of the figures below matter most. Startups are buying for a headcount they do not have yet, which makes the second and third tier of each ladder more important than the first. Check what the price becomes at ten people.
- How much does browser extensions software cost?
- Across the 20 browser extensions tools listed here, paid plans start between $1.79 and $9 a month, with a median entry price of $8.33. The most expensive single tier published in the category is $40 a month (Night Eye). 12 of 20 also publish a $0 plan.
- What is the cheapest browser extensions software?
- 9 of the 20 tools listed here cost nothing at all. Among the ones that charge, Keeper has the lowest published entry price at $1.79 a month. Cheapest and best value are different questions: check which tier the capability you need actually appears in before you compare starting prices.
- Is there free browser extensions software?
- Yes, 12 of 20 tools in this category publish a plan priced at $0. 9 of them are free outright, with no paid tier above. A tool is only counted as free here when it publishes a $0 plan, an open-source licence, or a starting price of zero, a free trial does not count.
- How is browser extensions software usually billed?
- free (5), freemium (3), counted across the 20 listings on this page. The distinction that costs money is per-seat versus flat: a per-user plan at the same headline price scales with your headcount and a flat subscription does not. 1 of 20 tools also keep at least one tier unpriced and sold by quote.
- What does browser extensions software actually cover?
- The 20 tools on this page do not describe themselves the same way. The subject tags they carry most often are browser (20), extension (20), productivity (5), screenshot (3), accessibility (2). That spread is the honest answer to what the category means in practice: it is not one product shape, and two tools filed under browser extensions may overlap on very little.
- How many pricing tiers do browser extensions tools offer?
- 12 of 20 tools here publish a plan breakdown, and the median one has 1 tiers. 3 of 20 publish three or more. More tiers is not generosity, it usually means the capability you are buying for sits two rungs above the advertised price, so price your shortlist at the tier that contains it.
- How many browser extensions tools are listed on Softwr?
- 20 approved browser extensions listings appear on this page, including AdBlock Plus, Awesome Screenshot, BuiltWith, Capital One Shopping. Each links to a full breakdown with its pricing tiers and plan detail, and the category can be filtered by price and sorted by rating above. You can also read the shortlist view at /best/browser-extensions, which ranks the same set by published rating.
