Rankings are okay, but dashboard updates can lag sometimes.
Solid free API library for builders.
Cloudflare blocks make testing a bit annoying at times.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Ready-to-use endpoints that GPT builders can add to a Custom GPT's Actions without hosting their own server.
Follow how Custom GPTs and AI apps perform over time with rankings and trend signals.
Connect APIs to a GPT or website through configuration rather than custom development.
Utilities aimed at creators who want to publish a site around their GPT.
Trends for GPTs lives in the Gapier ecosystem, a set of utilities built for people who create and publish Custom GPTs. The tool tracks how GPTs and AI apps perform over time, surfacing rankings and trend signals so creators can see which assistants are gaining attention and which categories are heating up.
Alongside the tracking side, Gapier is best known for handing GPT builders a library of free Actions APIs. Instead of writing and hosting their own backend, creators can wire ready-made endpoints into a GPT's Actions configuration — or into a website — so the assistant can fetch data, run a task or connect to a service. This no-code/low-code approach lowers the barrier for turning a prompt into a functional assistant.
Because Gapier is an independent project, it is not an official OpenAI offering, and GPT builders should confirm each API's limits and terms before depending on it in production. The 403 responses on gapier.com and trends.gapier.com indicate bot protection is active, which is common for hosted services of this kind.
Plug a free Gapier Action into your GPT so it can pull real data or trigger a task without you running a backend.
Use trend and ranking data to decide which kind of assistant or app to build next.
Use Gapier's website tools to wrap a GPT in a public-facing site without hand-coding an API layer.
