Toolweight Club
Toolweight Club is a paid membership for founders. It tells you how your product stands against its rivals on Toolweight, what changed, what buyers want, and whether AI agents recommend it.
It reads the same sourced, dated data as the public comparisons. Paying never changes that data: see the trust rules.
One tracked product, unlimited seats. No trial, no refunds. Cancel at any time.
What you get
1Competitor change radar
Same-day alerts when a rival changes something.
- Watches each rival's verified values on Toolweight, its pricing, changelog and docs pages, GitHub releases, npm and PyPI versions, status incidents, funding, job posts, new terms and regions, and Hacker News, Reddit and X threads.
- Every source is fetched at least once a day. An alert reaches you within 24 hours of the change.
- Each alert starts with one sentence on what changed and why it matters, with a severity: high for pricing, limits, regions and terms; medium for a feature, a release, an incident or funding; low for docs and community.
- By email, signed webhook, private RSS feed or the dashboard timeline. Set a minimum severity for each channel, mute a rival or a source, or take one daily or weekly digest.
2Where you rank
Where your product beats or loses to each rival.
- For each category of your product: position, score and coverage, under the default weights and under each weight set you save.
- For each rival: the fields where you win, lose and tie, and the size of each difference.
- Rank over time, back to the first record Toolweight has.
- Each value links to its source and its verification date.
3Buyer demand signals
What buyers in your categories want.
- The fields buyers weight most, the tools they compare together, the questions they ask (grouped by theme, with example threads) and which AI assistants send traffic, each with its trend.
- From the queries agents send to the Toolweight MCP server and API, AI crawler and referral hits, search volume, and Hacker News, Reddit, X and GitHub threads.
- Aggregates only. A figure with too few events is not shown, so no single caller can be identified.
4Gap finder
Unmet needs worth building for.
- Fields with high buyer weight that no tool wins.
- Questions that no listed tool answers: a region, a limit, a pricing model, an integration.
- Comparisons that buyers ask for and Toolweight has no category for.
- The fields where a change to your product would move its rank the most, with the rank it would reach.
- Each gap has a demand score, the evidence behind it with links, and the date it was first seen.
5Agent visibility audit
Whether AI agents recommend your product, and what to fix.
- Each week Toolweight asks a fixed set of buyer prompts to the flagship models of Anthropic, OpenAI and Google, with web search on and off.
- For each answer: whether your product was named, its position among the tools named, what was said about it, and the sources the model cited.
- You see the recommendation rate and average position by model over time, the same for each rival, and each statement about your product that is wrong against Toolweight's verified values.
- A fix list in order of expected effect: an llms.txt, a clear pricing page, docs that agents can read, an MCP server, a wrong claim on a cited page.
- Add up to 20 prompts of your own.
6Accuracy badge
Shows buyers that your pricing data is verified.
- A badge for your own site: "Pricing verified by Toolweight", with the verified date and a link to your tool page. Toolweight serves it live.
- It is live only while every pricing value of your product was verified in the last 30 days. It never shows a stale date as verified.
- You get an alert 7 days before a value goes stale. Toolweight verifies the value in its normal flow; a member does not.
- Needs a verified domain: a DNS TXT record, or a sign-in from an email address at your domain.
7Feature parity matrix
A comparison table of your product against its rivals that is always current.
- You choose the rivals and the field groups. Inside a group every field is shown.
- Each cell shows the value, the confidence level and the verified date.
- Live in the dashboard, as an embed for your own site, as CSV, Markdown and PNG exports, and through the API and MCP.
8Launch impact tracker
How a release moves your product's standing.
- Launches are detected from your changelog, GitHub releases and pricing page. You do not enter them by hand.
- Before and after each launch: rank and score per category, under the default weights and each of your weight sets.
- The change in agent recommendation rate, week by week.
- Head-to-head flips: the rivals you now beat or lose to, and on which fields.

Sample report
The first two blocks are built from Toolweight's public data for Sandbox providers when this page is built. They show E2B because its data is public. That says nothing about who is a member: membership is private. The last two blocks are examples, and say so.
Where E2B ranks in Sandbox providers

A change radar alert
Illustrative example · not real dataWhat an alert looks like. The rival, the figures and the link are invented.
High · Pricing page · seen 09:12 UTC · Rival A
Rival A raised its entry plan from $20 to $25 a month and removed custom domains from the free tier, which narrows its price lead over you.
Before: "Starter $20 / month". After: "Starter $25 / month". May affect: entry price, free tier. Queued for re-verification in the normal flow.

Trust rules
- Paying changes no public data
- Membership never changes a public value, a score or a rank. No public page, ranking, MCP answer or API answer reads membership.
- Paying buys no listing
- A tool is listed on editorial merit only. A product that is not listed goes into the same listing queue as any other.
- No priority
- A member cannot edit a value. A member's correction goes through the same report queue and the same sourcing rules as a report from anyone.
- Membership is private
- Who is a member, which product they track and which rivals they watch are private. No other member, no vendor and no public page can see them, by name or in counts.
- Embeds cannot hide a loss
- A badge or a matrix on a member's own site is served live by Toolweight, shows the verified date and links to the public category page. It cannot hide a row where the member loses, and it falls back to a plain "View on Toolweight" link when the membership ends.
- Still no paid placement
- No affiliate links and no sponsored placements, as before.
Questions
Who is Toolweight Club for?
Founders and product teams of developer tools who want to know how their product stands against its rivals on Toolweight, what changed, what buyers want, and whether AI agents recommend it.
How much does Toolweight Club cost?
USD $100 a month, or USD $1,000 a year, which is two months free. One membership covers one tracked product and unlimited team seats. There is no trial and there are no refunds. You can cancel at any time and keep access to the end of the paid period.
Does a membership change my product's rank on Toolweight?
No. Paying never changes a public value, a score, a rank or a listing, and it gives no priority. A member's correction goes through the same report queue as a report from anyone.
Do I have to own the product I track?
No. Anyone can subscribe, and the tracked product can be any tool on Toolweight. Only the Accuracy badge and the matrix embed need proof that you control the product's domain.
What if my product is not on Toolweight?
You can still subscribe. The product goes into the normal listing queue and is added only if it fits a category. Until then the features that need Toolweight data show "pending", and the change radar works at once on the rivals you add.
Can anyone see that I am a member?
No. Membership, the tracked product and the watched rivals are private. The only public sign is the Accuracy badge or an embed, and only if you choose to publish it.
What happens when I cancel?
All features stop at the end of the paid period, and a badge or embed falls back to a plain link. Your settings, custom weights and history are kept for 90 days, so that a resubscribe restores them, and are then deleted.
