Fixa is a cloud-native AI coding agent that goes beyond code completion to handle end-to-end project scaffolding, deployment, and iterative refinement — all without any local setup. Launched on Product Hunt today, it lets developers describe a project in plain language and returns a running, deployed application within minutes. Unlike Bolt, Replit, or Lovable — which run in browser-based sandboxes — Fixa provisions real cloud infrastructure (compute, database, CDN) on your behalf and maintains persistent agent state between sessions. You can leave a session and return to find the agent has continued iterating on your project based on usage data it collected from real traffic. The differentiator is the feedback loop: Fixa monitors the deployed app's error logs and user interactions and proactively proposes fixes or improvements without being asked. It supports Node.js, Python, and Go projects, connects to GitHub for version control, and integrates with Stripe, Supabase, and Cloudflare out of the box.

Kelviq is the all-in-one revenue infrastructure platform built from the ground up for SaaS and AI companies. As a Merchant of Record, Kelviq takes full liability for global sales tax (VAT, GST), fraud, and regulatory compliance — letting AI startups sell in 100+ countries without ever registering for a foreign tax ID. It supports subscriptions, usage-based billing, feature entitlements, and one-time purchases through a single API. The AI-specific angle is real-time metering: Kelviq can track every token, API call, compute unit, or active user with zero reported latency. This is critical for AI products where costs spike unpredictably and customers need granular visibility into what they're being charged for. Pricing is 2.9% + 40¢ per transaction (up to $5K/month volume) or 3.5% + 40¢ thereafter, with no monthly fees — competitive with Stripe + a separate tax tool. Built by the team behind ParityDeals (a price localization tool with proven market fit), Kelviq launched to #1 on Product Hunt today with 430 upvotes. The founders' experience running a SaaS business internationally gives them genuine insight into the pain points they're solving.
Reviewer scorecard
“The persistent agent state between sessions is genuinely new — most AI coding tools forget everything when you close the tab. The automatic error monitoring and proactive fix proposals are early-stage but already useful for catching dumb mistakes in side projects.”
“Token-level metering with real-time entitlement enforcement in one API is the infrastructure I've been duct-taping together with Stripe + Lago + TaxJar for years. Kelviq collapsing that stack is worth serious evaluation, especially for early-stage AI products.”
“Letting an AI agent autonomously modify production code based on user behavior data is a significant trust leap. The free tier is one project, and cloud infrastructure costs aren't fully transparent at signup. Wait until the auto-deploy feature has more community vetting before pointing it at anything real.”
“Merchant of Record is a trust-intensive category. If Kelviq has a billing outage, your revenue stops. I'd want to see their uptime track record, enterprise SLAs, and how disputes are handled before migrating a live AI product off Stripe.”
“This is what 'AI-native software development' actually looks like — not just autocomplete, but an agent that's accountable for the running system. The feedback loop from production traffic to code changes is a glimpse at how most software will be maintained in five years.”
“As AI agent economies mature, usage-based billing at token granularity will be table stakes for monetization infrastructure. Kelviq is positioning at exactly the right layer — the picks-and-shovels for the agentic economy.”
“For non-technical creators who want to ship a product without learning DevOps, Fixa removes the biggest friction points: hosting, databases, and deployment. I spun up a newsletter landing page with a waitlist in under 10 minutes.”
“The pre-built hosted checkout and customer portal mean creators and solopreneurs launching AI tools don't need a backend engineer to handle billing. That's a genuine unlock for indie AI product launches.”
