AgentKit sells kits for AI coding agents, programs such as Claude Code, Codex or Cursor that read a code base, write and run code and edit files on a developer's computer at the developer's request. A kit is a folder of plain-text instructions and small scripts that the agent loads: skills (instructions for one kind of task, loaded when that task appears), subagents (separate agent roles, for example a planner or a code reviewer, that the main agent can hand work to), slash commands such as /ak:plan and /ak:cook, and hooks, scripts that the agent runs before or after a tool call, for example to ask for approval before a force push. The home page lists "108+ Skills", "95+ Commands" and "45 Subagents". The product launched as ClaudeKit, "Built on Claude Code by Anthropic", and was renamed AgentKit in 2026 when it added other agents.
The founder is Duy Nguyen from Vietnam, who writes as Goon Nguyen and signs the sales page as "Founder & CTO, AgentKit 18+ years building systems at scale". TrustMRR, a service that reads revenue through the seller's own payment account, gives a founding date of 7 October 2025 and reads the revenue from Polar, the payment platform that sells the kits. It shows US$10,411 in November 2025, a best month of US$16,040 in March 2026, then US$4,529 in May, US$2,641 in August and US$1,819 in September. By 27 October 2026 the total was US$82,195. The kits are sold once, not by subscription: the profile shows a monthly recurring revenue (MRR, the monthly value of active subscriptions) of only US$27.77.
The revenue figures are grade A: TrustMRR reads them through an API key from Polar. Sales paid by Vietnamese bank transfer go through another processor, Sepay, and are not in that figure, so the real total may be higher. The team size, user counts and ratings are the founder's own statements, grade C. The page also shows earlier companies that sold tools to make programmers faster, and why they failed.
How much revenue does AgentKit (formerly ClaudeKit) make?
Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.
| Fact | Value | Grade | How we know | Sources |
|---|---|---|---|---|
| Verified revenue, all time, to 27 October 2026 | US$82,195 | A | TrustMRR, read from the company's Polar account through an API key; revenue last synced 27 October 2026 at 02:22 UTC. Last 12 months: US$80,601. Sales by Vietnamese bank transfer through Sepay are not read by TrustMRR. | [1, 7] |

How to read this table: a grade A value was read by TrustMRR from the company's Polar account through an API key. A grade C value is what the founder or the company's own pages state. A "calc" value was computed on this page from the rows above it.
| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| AgentKit Engineer | 99 one-time | 100+ skills, 30+ workflows and AI subagents for software engineering | |
| AgentKit Marketing | 99 one-time | 12+ MCP integrations and workflows for research, sales and content | |
| AgentKit Bundle | 149 one-time | Engineer and Marketing kits plus a 1-year, 3-device desktop app licence | |
| AgentKit App, 1 device | 4.08 | US$49 a year; monthly figure calculated | |
| AgentKit App, 3 devices | 8.25 | US$99 a year; monthly figure calculated |
The kits are one-time purchases with lifetime updates and a 14-day money-back guarantee (30 days in November 2025). The bundle includes a one-year, three-device licence for the desktop app. The buyer also needs a paid plan or API account with the AI provider of the coding agent; that cost is not part of these prices. In November 2025 the only product, ClaudeKit Engineer, cost US$99, shown as reduced from US$149.
When did AgentKit (formerly ClaudeKit) launch, and how did it grow?
From ClaudeKit, one US$99 kit for Claude Code, to AgentKit with three products for seven coding agents, in about twelve months. Each entry carries its grade.

Why did AgentKit (formerly ClaudeKit) work?
Four causes, in the order they mattered. Each one is a reusable lesson.
Selling a tested set of instructions
A coding agent works better with a written plan, fixed roles and checks, but each developer had to discover these by trial and error. The kit sells that work: the November 2025 page called its author a "18+ Year CTO" who "burned millions of Claude tokens finding what works". The buyer gets plain-text files that they can read, change and keep.
One payment, no subscription
A kit costs US$99 once, with updates included. This removes the objection of another monthly bill next to the AI provider's plan, and the money-back guarantee if the kit "doesn't save you 10+ hours" lowers the risk further. The cost is that revenue depends on new buyers every month, and the verified MRR is only US$27.77.
Referrals from buyers
From the first month the site offered buyers 20% of each sale they refer, later up to 40%. The product page shows the arithmetic: "$19.80 per referral" and "$1,980 with 100 referrals". No source says what share of sales came from referrals, so this page leaves the channel unknown.
From one agent to seven
ClaudeKit was built for Claude Code only. As other coding agents spread, the product was renamed AgentKit and adapted to seven of them, and a marketing kit and a desktop app were added. The changelog shows frequent releases, many of them automated.
How it was built
These details come from the company's own pages, its changelog and its legal pages. They are grade C. [4, 6, 7, 8, 14]
- The kits are files for the coding agent: skills, subagent definitions, slash commands and hook scripts, installed with the company's command-line tool, first called ck and now ak.
- The first version was built on Claude Code with Anthropic's Sonnet 4.5 model, according to the November 2025 page. The current kits also target Codex, Cursor, Antigravity, Pi, Oh My Pi and DeepSeek Harness.
- Polar takes card and PayPal payments, Sepay takes Vietnamese bank transfers, and the home page promises "Instant license-key access". Early buyers received access through invitations to a GitHub repository, which the privacy policy now calls legacy.
- The website is hosted on Vercel. Resend sends the transactional email. Google Analytics, Umami and Google Tag Manager measure visits.
- Releases are published by GitHub Actions; the changelog page lists each release with the author "github-actions[bot]".
- The site also sells a partner product, ReelCrew, a video toolkit for Claude Code built by another team.
Tools named in the sources
Each one opens its page in the Tools tab, with every story that uses it.
Who tried this before AgentKit (formerly ClaudeKit), and why did they fail?
Four companies in the Loot Drop database sold tools that promised to make programmers faster or their code better, before AI coding agents existed or as they arrived. The values below are from that database and are not independently verified.
Kite DevTool
The promiseAI code completion inside the programmer's editor.
Why it diedThe database summary says GitHub Copilot, built on a much stronger OpenAI model, arrived in June 2021 and made Kite's older models obsolete, while Kite never found a way to make developers pay.
Fig DevTool
The promiseAutocomplete and visual command builders for the terminal.
Why it diedThe database summary says users loved it and used it daily, but too few of them paid, because developers have a very low willingness to pay for terminal tools.
Sider
The promiseAutomated code review and static analysis for development teams.
Why it diedThe database summary says the market split between free open-source tools and large enterprise platforms, and Sider was squeezed between them.
Light Table/Eve
The promiseAn editor that shows code results in real time, then a new way for non-programmers to build apps.
Why it diedThe database summary says professional developers stayed with the editors they already used, and the pivot to Eve lacked focus and resources.
The failed startups come from Loot Drop, a free database of dead startups, retold here in our own words. Loot Drop describes its entries as AI-assisted summaries of public sources, so these cards carry no evidence grade.
What changed
Kite, Fig and Sider each built a large piece of software, an AI model, a terminal layer or an analysis engine, and needed millions of dollars before they could sell it. Fig shows the other problem of developer tools: people who use a tool every day still do not pay for it. All three ended when a free or bundled alternative became good enough.
AgentKit builds almost no software of its own. The coding agent and the model come from Anthropic, OpenAI and others; the kit is instructions and scripts on top. That is why one founder could ship it within weeks and charge from the first day. The same fact is the risk: the instructions can be copied, free kits exist, as the founder's own blog post of March 2026 admits, and the agent makers add their own skills and workflows. Verified revenue fell 88.7% from March to September 2026.
Can one person copy AgentKit (formerly ClaudeKit) now?
The method, yes. The timing, no.
The opening was the months after Claude Code made skills and subagents common and before free collections were everywhere. Today buyers can compare paid kits with many free ones, and the verified revenue shows the effect. What can still be copied is the structure: package expert know-how for a new tool as files the buyer owns, sell it once with a refund promise, and pay buyers to recommend it.
Where it is still open: Kits for one industry or one stack are still open: for example rules and checks for medical-device software, banking code or a single framework, where generic free kits do not know the requirements.
- 1Use the new tool every day until you have a set of instructions that clearly works better than the default.
- 2Package it so that it installs with one command and can be read and changed by the buyer.
- 3Sell it once with a short refund period, and connect a payment platform that can later prove the revenue.
- 4Offer buyers a stated commission for each sale they refer, and keep the kit updated as the tool changes.
What could go wrong for AgentKit (formerly ClaudeKit)?
The risks are the mirror image of the causes above.
Revenue fell by most of its peak
Verified revenue was US$16,040 in March 2026 and US$1,819 in September 2026, 88.7% lower. The last 30 days were 32.5% above the 30 days before, at US$2,365. One-time sales need new buyers every month, and there is almost no recurring revenue.
Income wording around the referral program
The product page heads its affiliate section "Turn AgentKit Into Passive Income" and shows "$19.80 per referral", "$198 with 10 referrals" and "$1,980 with 100 referrals", which is the stated 20% commission on a US$99 kit multiplied out. Aiolum accepts an affiliate program that states its commission. The same page has a "First Feature ROI" box that values 10 saved hours at an assumed US$100 an hour and shows "Net profit: $901"; this is a claim about saved working time, backed by a refund "If it doesn't save you 10+ hours", not a claim about money earned from the product. A blog post of 19 August 2026 on extra income says vibe coding does not "guarantee a passive income stream".
The founder's other company
The founder's GitHub profile says "Founder @ wearetopgroup.com". That site describes T.O.P Group as "doanh nghiệp cung cấp giải pháp sáng tạo được thành lập năm 2014 và có trụ sở chính tại Thành phố Hồ Chí Minh" (translation: a creative-solutions business founded in 2014 with its head office in Ho Chi Minh City) and shows "40 + Thành Viên" (translation: 40+ members). No source says that its staff work on AgentKit, and the AgentKit pages do not mention it. The GitHub profile also lists other products of the founder: GoClaw.sh, TOSE.sh, Dewee.sh, AgentBrain.sh and AgentWiki.cc.
Built on other companies' agents
The kits only work inside coding agents made by Anthropic, OpenAI and others, and the buyer pays those providers separately. The first name, ClaudeKit, used Anthropic's product name; the 2026 rename post does not say why the name changed. Another developer also published a project called claudekit, which the founder's blog mentions.
Unclear proof on the sales page
The home page shows "4.9/5 349 ratings" next to "12 customer reviews" without saying where the ratings come from, and the user counts (7,104 on TrustMRR, 3,800+ on Discord) are the founder's own figures.
Part of the revenue is not verified
TrustMRR reads only the Polar account. Vietnamese buyers can pay by bank transfer through Sepay, and those sales are not in the US$82,195. The partner product ReelCrew is also sold on the site; whether its sales pass through the same Polar account is not stated.
