Picking a live chat platform in 2026 is harder than it should be. The market has more options than ever and almost every vendor claims AI features, GDPR compliance, and unlimited everything. Here's a practical comparison of the platforms small UK businesses actually shortlist.
The four main options
Intercom
The premium incumbent. Best-in-class product, deep integrations, and an AI bot ("Fin") that's genuinely good. The catch is price — Intercom has historically been priced for venture-backed B2B SaaS, not for a 4-person UK business. If budget isn't a constraint and your team will use the platform every day, Intercom is hard to beat.
Tidio
Lighter than Intercom, much cheaper, popular with e-commerce. The free tier is real and the Shopify integration is solid. The AI bot is decent but the knowledge base feels less mature than the chat side. Good fit for D2C brands on a budget.
Zendesk
The veteran ticketing system that added chat and now AI on top. Best if you already use Zendesk for tickets and want everything in one place. Overkill for a small team that just wants chat.
tawk.to
Free, forever. Genuinely free, no trial. The trade-off is that the chat UX is dated, the AI is rudimentary, and "free" means your data lives in their cloud on their terms. Fine for a side project; not ideal for a business that handles personal data.
Silux Chat (us)
UK-based, free plan with 1,000 messages and 2 bots, GDPR-compliant by default, single inbox for web + WhatsApp, and an AI bot trained on your knowledge base. We built it because the existing options either cost too much (Intercom) or weren't UK-first (everyone else). Honest take: not the best fit if you need a deep ticketing system or are already committed to Zendesk.
What to actually compare on
Most comparison articles miss the practical questions. Ask:
- **Is there a real free tier?** Some platforms call a 14-day trial a "free plan."
- **Where does my data live?** UK/EU residency matters more than vendors admit.
- **Will the bot use my knowledge base, or just canned replies?** This is the biggest UX gap between modern and legacy tools.
- **Can I get a DPA without upgrading to enterprise?** You shouldn't have to.
- **Does the WhatsApp integration share a knowledge base with the website widget?** Otherwise you're running two bots.
- **What does the bill look like at 10× current volume?** Some platforms get nasty as you grow.
Our recommendation
If you're in the UK and want a single platform that does web + WhatsApp + AI bot, with a real free plan and a DPA out of the box, give Silux Chat a try. If you're already on Shopify and want the easiest install, Tidio is a fine choice. If you have the budget and want the most polished product, Intercom is still the gold standard.
What you should *not* do is sign a 12-month contract before trying the free tiers of two or three platforms with your real customer questions.
