KaziBuilder is a free BYOK alternative to Bolt.new. Bolt's free tier caps at 1M tokens/month and Pro costs $25/month for token packs; KaziBuilder charges nothing and you pay your provider's raw per-token rates — typically cents to a few dollars per site — with any of 12 providers and no monthly pack to use up.
Bolt.new (by StackBlitz) is a strong in-browser AI builder. Like Lovable it resells AI usage — you buy token packs from Bolt. KaziBuilder takes the BYOK route: connect your own provider key and pay raw per-token rates with no subscription. Bolt's own team also maintains bolt.diy, an open-source BYOK variant — which says something about the demand for this model.

Common questions
Is KaziBuilder a free alternative to Bolt.new?
Yes. KaziBuilder charges nothing — you connect your own provider API key and pay raw token rates. Bolt.new's free tier is capped at 1M tokens/month (300K/day); meaningful usage needs the $25/month Pro plan.
Can I use my own API key with Bolt.new?
Not with the hosted Bolt.new — it bills in its own token packs. The open-source bolt.diy project supports BYOK but you must run it yourself. KaziBuilder is hosted, free, and BYOK out of the box.
What is the difference between buying Bolt tokens and BYOK?
Bolt sells you a monthly allotment of tokens it buys from providers. With BYOK you skip the middleman: your key, your provider's prices, your spend limits, and unused budget simply stays unspent — there is no monthly pack to use up.
Verdict
Choose Bolt.new for its polished StackBlitz-powered dev environment and a single monthly bill. Choose KaziBuilder to pay raw provider prices with no subscription — or bolt.diy if you want open source and are happy self-hosting.
