HookReplay.dev's answer

Still early — just launched. Currently used by indie developers and small teams debugging Stripe and Shopify integrations. No big logos yet. Focused on building a great product first.

HookReplay.dev's answer

With ngrok, every code change means triggering another webhook. Add a log? Trigger again. Set a breakpoint? Too late, it timed out. Trigger again. With HookReplay, you trigger once. Then replay 100 times while you debug. Same webhook. Same payload. Unlimited attempts to get your code right. That's not a small difference — it's hours saved per debugging session.

Split Fee's answer:

Most "split fee networks" are just directories or social groups where agencies post and hope someone responds. Split Fee is an actual matching engine. It scores candidate-vacancy pairs, handles the legal agreements (non-circumvention, self-billing), automates invoicing and fee splits, and manages the entire placement lifecycle from match to payment. Everything that normally requires trust, phone calls, and spreadsheets is handled by the platform.

Developers who integrate third-party webhooks Stripe, Shopify, GitHub, Twilio, Paddle, etc. Basically anyone who's ever clicked "Send test webhook" more times than they'd like to admit.

Split Fee's answer:

UK recruitment agencies; from boutique firms with a handful of consultants to mid-sized agencies with specialist sector coverage. Any agency that has either strong candidates without the right vacancies, or client vacancies they can't fill from their own candidate pool. Split Fee turns those dormant assets into placements.

HookReplay.dev's answer

11pm on a Sunday. A customer's Stripe payment went through, but their subscription wasn't created. I needed to debug the webhook handler. Set up ngrok. Triggered a test payment. Added a log statement. Triggered again. Set a breakpoint — webhook timed out before I could step through. Triggered again. Changed the URL in Stripe because ngrok restarted. Triggered again. Three hours later, I found a typo in my event type check. I remember thinking: I just re-triggered the same webhook 40+ times. Why can't I just capture it once and replay it until I find the bug? That's the moment HookReplay was born. The tool I wished existed that night.

Split Fee's answer:

Abbie, our founder, knew that although split fee arrangements have existed in recruitment for decades, the process has always been manual: find a partner agency, negotiate terms, trust them with your candidate data, chase invoices. Most agencies avoid it because the overhead and risk outweigh the reward. Abbie built Split Fee to remove that friction entirely, with automated matching, progressive identity disclosure, built-in legal agreements, and automated billing, making split placements as straightforward as direct ones.

ASP.NET Core for the backend, PostgreSQL for storage, WebSockets for real-time forwarding to the CLI. The CLI is built in .NET and distributed via npm — runs on macOS, Windows, and Linux. Nothing fancy. Boring tech that works.

Split Fee's answer:

A next-generation serverless platform, built for AWS.

HookReplay.dev's answer

Three things most webhook tools don't do: 1- Replay the same webhook unlimited times 2- Edit payloads before replaying (test edge cases) 3- Keep a full history of every webhook received HookReplay does all three, plus real-time forwarding like ngrok.

Split Fee's answer:

Split Fee is the first purpose-built platform for split fee recruitment in the UK. Instead of relying on LinkedIn groups, WhatsApp messages, and manual agreements, agencies upload their candidates and vacancies and the platform automatically matches them across agencies.

Candidate identities are revealed gradually; anonymised at first, then progressively disclosed as both sides accept, so agencies can collaborate without the risk of circumvention.
