Automated Booking Software for Freelance Developers
Your open-source scheduling tool and developer booking page — automate the meetings that pay the bills without a single email chain.
Why do freelance developers waste hours on scheduling that should be instant?
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.
Why off-the-shelf schedulers feel wrong to engineers who ship for a living
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.
Everything Developers need. Nothing they don't.
Purpose-built scheduling features for your practice — without the bloat.
Meeting Types for Every Project Stage
Create separate booking types for discovery calls, technical scoping sessions, weekly syncs, and code reviews — each with its own duration, buffer, and booking link.
Global Timezone Handling
Clients book in their timezone, you see everything in yours. DST transitions handled automatically across every calendar region.
Privacy-First and Open Source
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.
Auto Video Conferencing Links
Google Meet, Microsoft Teams, or self-hosted MiroTalk rooms generated automatically with each booking — no copy-pasting links before every call.
Embed on Your Portfolio Site
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.
Webhooks and Calendar Sync
Sync with Google Calendar, Outlook, Nextcloud, or any CalDAV provider. Trigger webhooks on new bookings to connect with your project management workflow.

Common scheduling scenarios
How other Developers use Tymeslot every day.
How do freelance developers convert inbound leads without losing momentum?
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.
- Embed a 'Book a Discovery Call' widget directly on your portfolio's contact or hire page.
- The client picks a 30-minute slot from your live availability — no email required.
- A video conferencing link is generated automatically and sent to both of you.
- You walk into the call prepared; the client arrives without friction.
How do developers manage recurring syncs with long-term clients?
Ongoing retainer clients need regular check-ins — weekly or fortnightly syncs that should feel lightweight, not like calendar coordination overhead every single time.
- Create a dedicated 'Weekly Sync' meeting type with a 45-minute duration and 15-minute buffer.
- Share the private booking link with your retainer client at the start of the engagement.
- The client self-books each sync directly into your calendar with no prompting needed.
- Both parties receive automatic reminders so nothing slips through.
How do developers scope new projects with distributed teams?
Technical scoping calls involve stakeholders across different cities and timezones. Getting everyone aligned on availability without a flurry of messages is half the battle.
- Set up a 'Technical Scoping' meeting type with a 60-minute duration and your required advance notice.
- Share the booking link with the client contact, who coordinates internally on their end.
- Tymeslot checks your real-time availability across all connected calendars and blocks the slot.
- All attendees receive calendar invites with the video link and agenda reminder.

"I was using Calendly until a client pointed out it was loading Facebook Pixel and Google Analytics on the booking page. Switched to Tymeslot, self-hosted it on my VPS, and now I tell every client it's privacy-first — it's actually a selling point."
