COST ANALYSIS

Fixed Per-Seat Subscriptions vs. Usage-Based Wallet

Legacy AI editors charge a flat $20/month per seat—whether a developer codes for 1 hour or 100. With Kernax, you only fund actual engineering output.

Assinaturas fixas tradicionais (15 devs)
$300/month, guaranteed
Even idle devs cost $20/mo
  • Mandatory per-seat fee even on vacation or light weeks
  • Throttled "slow-pool" queues after fast-request limits
  • Separate credit card charges for every new hire

~$80–120/month, actual usage
$0 seat fees · Pay only for active tasks
  • Fund one wallet; developers draw only when building
  • AST-scoped context cuts wasted prompt tokens
  • Hard per-developer spend limits prevent surprise bills

FAQ

Frequently Asked Questions

How do I get access during the Closed Beta? +
Request access on our waitlist page. We onboard developers in weekly batches—every approved account starts immediately with 20M free starter tokens, no credit card required.
Does my wallet balance ever expire? +
Never. Any balance you top up (starting from $5) stays in your account indefinitely until your agents consume it. There are no monthly resets or recurring charges unless you enable optional auto-reload.
What is Kernax Auto, and why does my balance last longer? +
Kernax Auto is our default, high-speed coding engine optimized specifically for agentic tool loops and AST-scoped edits. Combined with local Tree-sitter context pruning—which sends only relevant code nodes instead of entire repositories—your wallet stretches significantly further than raw chat wrappers.
Can I switch between models mid-project? +
Yes. You can switch between Kernax Auto, Claude 4.6, GPT-5.2 Codex, Gemini 3.8 Flash, and DeepSeek R1 directly from the chat selector at any moment using the same wallet balance.
