Partstack's answer

We're a next-generation search engine and digital marketplace for semiconductor and electronic component buyers & traders. Partstack was designed for today’s globally connected marketplace. One key difference is that we’re not a "pay-to-play" platform. Customers never pay a dime and approved suppliers can display their in-stock inventory without restriction.

Users can find more parts, more suppliers, and radically transparent pricing and inventory data—faster than ever before.

Graded Prompts's answer:

Every prompt is human-reviewed before it can be sold: a reviewer runs it on the model it's written for with varied inputs, checks that the instructions are complete and the variables labelled, and compares the seller's example outputs to what the model really produces. Prompts that pass earn a Graded Badge; the rest go back to their creator with specific feedback. Most marketplaces publish whatever sellers upload — the grading is the whole point here.

Partstack's answer

We've assembled the world's largest semiconductor supply chain and supercharged it with the power of modern search technology. And we're iterating and improving our marketplace every single day.

Partstack features the most diverse and comprehensive supplier stack of all electronic component marketplace platforms. Most importantly, our extensive component catalog is shared with users via product-rich data pages that feature insights that are simply not available on any other platform. In addition to form, fit, function, and standard trade compliance data, users can find information about part manufacturer leadership, financials, fab locations, and other key data points.

Graded Prompts's answer:

Because the risk sits with the marketplace instead of the buyer. Listings are verified before sale, example outputs are checked against reality, every purchase includes a perpetual personal-and-commercial license, and refunds come from Graded Prompts itself as merchant of record — within three days if a prompt doesn't perform as described. Free prompts and guest checkout mean you can test the quality bar without an account or any commitment.

Partstack's answer

Our primary audience consists of the builders, makers, and innovators who create the products that power our world. We built Partstack to make life (and sourcing!) easier for these everyday game-changers (i.e., electrical engineers, PCB design teams, semiconductor procurement professionals, distributors, product manufacturers, students, etc.). Whether they are independent hobbyists, a company of one, or a large-scale corporation (OEM/CM)—we make it easy for users to find their place in the stack.

Graded Prompts's answer:

People who use AI tools for real work but don't want to fight with prompt engineering: content creators filling a posting calendar, marketers mocking up campaigns, print-on-demand sellers, self-publishing authors, and video makers. On the other side of the marketplace: prompt engineers who want to monetize their craft — they keep 85% of every sale with no listing fees.

Partstack's answer

The platform is the brainchild of a team of electrical and software engineers who wanted to build the world’s most comprehensive electronic components database and marketplace platform. We like to say that Partstack was built for engineers, by engineers with one goal in mind: Marketplace diversity and transparency.

Graded Prompts's answer:

It started with a familiar frustration: AI credits drained on generations that came out wrong because the prompt was broken — and prompt marketplaces that publish anything, so buying one was a gamble too. Graded Prompts was built to be the marketplace we wanted to buy from, where a human tests every prompt on its real model before it goes on sale. It launched in 2026 as an independent, bootstrapped company.

Partstack's answer

An array of cutting-edge technologies come together to build our platform's "technological harmony." We take advantage of both client-side and server-side rendering to parse and manage the flow of data across our multi-vendor marketplace. We utilize direct supplier uploads and some programmatic interfacing to collect real-time pricing and inventory data to populate our supplier stack. Technologies such as Cloudflare and SSL certificates are used to ensure user authentication, data encryption, and overall platform security. Finally, several in-house, custom-built proprietary technologies are used to power our search engine, stack logic, and other features of our marketplace.

Graded Prompts's answer:

Next.js and React on the frontend, a Java Spring Boot API, and PostgreSQL, hosted on AWS with CloudFront. Stripe handles payments and seller payouts, and the AI-powered search runs on OpenAI embeddings.

Partstack's answer

Partstack supports users from the world’s largest manufacturing companies (OEMS) and contract manufacturers. We also proudly serve tinkerers and hobbyists.
