Indie Seller Weekly #5: Bring-Your-Own-Key AI Tools Sold for a One-Time Price Are Multiplying

Every week I count the websites that newly put up checkout links on 8 payment platforms (Stripe, Gumroad, Lemon Squeezy, Polar, Creem, Dodo, Paddle, Waffo) to see what people are selling, what is picking up, and which needs nobody has served yet.

This week's numbers

• The link graph picked up 4,735 new sellers this week. 833 sell software, and 584 of those are AI products. By platform: Stripe 3,387, Gumroad 951, Lemon Squeezy 174, Polar 155, Dodo 36, Creem 30, Paddle 2. Waffo still has no new sellers in the link graph.
• Last week's count has since grown to 6,450 (last issue said 6,307), and this week's will grow too.
• November is only one week old, so compare the last four weeks (October 12 to November 8) with the four before: 22,500 new sellers against 14,200. The share selling software is 18.4% against 18.8%, basically unchanged; the share of software that is AI rose from 58% to 63%.
• This week Polar had 3.3% of new sellers and Lemon Squeezy 3.7%, both below their October share (4.0% and 5.0%). One week says little; I will look again when November is complete.

Weekly numbers swing a lot: the link graph picks up new links in batches, and weeks have ranged from 1,100 to 6,500. Look at months for the trend.

5 new products worth a look

1. Drakar (drakar.mgcrea.io, Stripe): Claude Code and Codex in a native Mac window: the conversation, permission prompts, diffs and several sessions side by side, using a sixth of VS Code's memory. It drives the claude and codex already on your Mac, on your own subscription. The source is MIT; what is sold is the signed build, $14.99 once. Needs macOS 26.
2. Lume (lume.tild.io, Lemon Squeezy): one keystroke opens an AI panel over any app, and the answer goes back in at your cursor. It uses your own API key (OpenRouter, Anthropic, OpenAI or a local Ollama), kept in the Keychain; Lume never sees a request. 15 questions free, then €6.99 once.
3. Gatekeep (gatekeep.nanocorp.app, Stripe): guest screening for Airbnb hosts. Each booking request gets a risk score from the guest's review history and social accounts; risky ones are flagged and a polite decline goes out for you. $29/month for up to 5 properties, 14-day free trial, still in early access.
4. Levr (levr.ai, Stripe): a workspace for small-business loan brokers: client intake, AI autofill from uploaded documents, one application sent to several lenders, and commission tracking in one place. Free for brokers; the lenders pay. A two-sided pricing model worth remembering.
5. Tempr (temprhq.io, Stripe): one gate for a team's AI use. Claude Code runs on the company's Claude plan, Codex on ChatGPT, other tools on API keys, with shared budgets, secrets and personal data masked in prompts, rules on who can call which MCP tools, and logs. Free for 10,000 requests a month, Pro $49/month.

One play this week: users bring the key, you sell a one-time shell

Three of this week's five share one idea: they do not resell model credits. Users bring their own API key, or the Claude or ChatGPT subscription they already pay for, and the product sells only the interface and the workflow. Last issue's Asset Lab (models on your own Fal key) works the same way.

• The price can be low, and one-time: with no token costs to cover, there is no need for a monthly fee as a safety net. Lume is €6.99 once, Drakar $14.99, and the buyer does not take on another subscription.
• Sell "we never touch your data or your money": key in the local Keychain, requests straight to the model provider, source code public. These pages put that front and center. For people already paying for Claude or ChatGPT, it persuades better than "our model is smarter".
• For teams, the same idea becomes control: inside a company it turns into something like Tempr, selling budgets, permissions and logs.

The risk: a shell is easy for the model makers to build themselves, or for an open-source project to match. The ones that last tend to be tied to one concrete job (coding, writing, video) and get its details right.

Payment platform news

• Polar: a November 3 blog post announced an official ChatGPT plugin and an approved MCP server in Claude. Signing up, setting up pricing, entitlements, meters and credits, wiring it into your code, testing in a sandbox and migrating from another billing platform can all be handed to an agent in a chat. To install in Claude: /plugin install polar --marketplace polarsource/agent-toolkit. Source: https://polar.sh/blog/polar-for-claude-and-chatgpt
• Lemon Squeezy: the blog posted a "2026 Update" (the page dates it November 7). The co-founder admits support got slower and updates rarer over the past year while the team built Stripe Managed Payments, Stripe's own merchant of record. It supports merchants in 35+ countries today, public sign-up is coming "very soon", and the goal is an easy move over for Lemon Squeezy users. If you sell on Lemon Squeezy, start watching for the migration path. Source: https://www.lemonsqueezy.com/blog/2026-update
