An open-source scheduling tool and booking page that handles the meetings paying your invoices, with no email chain to babysit.
Updated June 30, 2026
You build automation for clients all day, then spend 20 minutes trading "does Thursday at 3pm work for you?" emails to book a 30-minute call. Every timezone conversion done by hand is a small tax on your attention. Every missed reply is a potential project that goes to someone else. And when clients notice you're using a booking tool that drops third-party trackers on them, it quietly undermines the trust you've worked to build.
Calendly, Acuity, and SimplyBook.me optimise for high-volume sales bookings — not for the small surface area of a freelance developer who needs three event types, a webhook, and a clean booking page they can embed without apologising for the third-party scripts it drags in. The gaps are practical: free tiers cap event types right around the number you actually need, webhook payloads are inconsistent across providers, and the booking widget arrives wrapped in tracking pixels that show up on your portfolio's Lighthouse report and undermine the privacy posture you sell to clients.
The time cost is concrete. A freelance backend or frontend developer charging £80–£150 per hour typically gives up 2 to 4 billable hours per week to manual scheduling, timezone maths, and chasing replies — between £8,000 and £25,000 of capacity per year. Add the deals lost when a prospect finds it easier to book elsewhere, and the gap widens. Tymeslot was built by developers, in the open, with a webhook-first event model, an embed that adds zero third-party requests, and a self-hosting path that lets your scheduling stack match the rest of your infrastructure.
Scheduling features shaped around how your practice works.
Create separate booking types for discovery calls, technical scoping sessions, weekly syncs, and code reviews — each with its own duration, buffer, and booking link.
Clients book in their timezone, you see everything in yours. DST transitions handled automatically across every calendar region.
No trackers, no ads, no analytics scripts loaded on your booking page. Self-host on your own infrastructure and own every byte of your clients' data.
Google Meet, Microsoft Teams, or self-hosted MiroTalk rooms generated automatically with each booking — no copy-pasting links before every call.
Drop a booking widget into your personal site or portfolio as an inline calendar, popup, or floating button — so inbound leads can book without leaving your page.
Sync with Google Calendar, Outlook, Nextcloud, or any CalDAV provider. Trigger webhooks on new bookings to connect with your project management workflow.
Same profession. Completely different scheduling experience.

How other Developers use Tymeslot every day.
A potential client lands on your portfolio after seeing your work. The difference between winning the project and losing it often comes down to how quickly they can get on a call with you.
Ongoing retainer clients need regular check-ins — weekly or fortnightly syncs that should feel lightweight, not like calendar coordination overhead every single time.
Technical scoping calls involve stakeholders across different cities and timezones. Getting everyone aligned on availability without a flurry of messages is half the battle.
