## GitRec

GitRec is a Chrome extension aimed at developers who want to discover GitHub projects without trawling trending pages. It plugs directly into GitHub and uses the repositories you have already starred as the signal for what to recommend, so the suggestions get more relevant as your star history grows. The extension pairs with a hosted backend and the whole stack — front end and recommender services — is published as open source under the gorse-io organization.

The recommendation logic comes from Gorse, an open-source recommender system that combines collaborative filtering with content-based similarity to score candidates. Because of that dual approach, GitRec can do two distinct things: push personalized suggestions to you on your GitHub feed, and build a 'similar repositories' list for any specific repo page you visit, which is handy when evaluating an unfamiliar library or looking for alternatives to a dependency.

GitRec is distributed for free through the Chrome Web Store (version 0.13 at the time of review, roughly 620 users, and a mixed 3.4/5 rating from a small handful of reviewers). The developer's privacy disclosure states that the extension does not collect or sell user data, and the source code is available on GitHub for anyone who wants to inspect or self-host the backend rather than relying on the hosted service.

**Pricing & Plans:** Completely free. GitRec is published as an open-source project and the Chrome Web Store listing has no paid tier, subscription, or in-extension purchase.

- **Star-based personalization:** Uses the repositories you have starred as the input signal, so recommendations track your actual interests rather than generic popularity.
- **Similar repository discovery:** On a popular repository page you can request a list of comparable projects, making it easier to compare libraries or find alternatives.
- **Gorse recommender backend:** Recommendations are generated by Gorse, an open-source engine that blends collaborative filtering with content-based similarity.
- **Fully open source:** Both the extension and its backend are published under the gorse-io GitHub organization, so you can audit the code or run your own instance.
- **No data collection:** The developer's Chrome Web Store disclosure states the extension does not collect or use your data, and does not sell it to third parties.

**Strengths:** Free and open source, so there is no paywall and the code can be inspected or self-hosted; Recommendations improve as you star more repositories, rather than being a static curated list; Two clear use cases in one small extension: a personalized feed and similar-repo lookup; Developer disclosure states no user data is collected or sold

**Limitations:** Small user base and a modest 3.4/5 rating from only a few reviewers; Quality depends on having a meaningful star history; new GitHub accounts will get weak suggestions; Relies on a hosted backend for recommendations, so an outage affects the extension's core feature

## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies
