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.

Thunderbolt is an open-source enterprise AI client built by MZLA Technologies, the Mozilla Foundation subsidiary behind Thunderbird. It gives organizations a private, self-hostable frontend for AI that supports Chat, Search, Research, and Tasks workflows — routing all inference through a backend proxy the org controls. Think Microsoft Copilot or Google Workspace AI, but one where your data never leaves your servers. Under the hood, Thunderbolt acts as a model-agnostic gateway. Admins can wire it to Anthropic, OpenAI, Mistral, or local Ollama instances from a single config file. The v0.1 release ships MCP (Model Context Protocol) support in preview and OIDC for enterprise identity providers, which is a meaningful differentiator for regulated industries. Why does this matter? Most enterprise AI tools still require cloud data egress, creating compliance headaches for finance, healthcare, and government. Mozilla's brand trust + open-source auditability + Thunderbird's install base (~25M users) gives Thunderbolt a credible distribution path that most scrappy AI startups can only dream about. Keep an eye on the MCP integrations as those mature.
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.”
“The OIDC support and multi-backend inference proxy out of the box are genuinely useful. Most open-source AI frontends make you roll your own auth from scratch. Mozilla's Thunderbird team knows enterprise distribution — this isn't some weekend project that'll be abandoned in a month.”
“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.”
“It's v0.1 and MCP support is labeled 'preview,' which means it's probably buggy. The real question is whether organizations trust Mozilla — a company that's struggled to monetize Firefox — to own their critical AI infrastructure. Adoption will be slow in regulated industries without a real support contract.”
“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.”
“Enterprise AI is currently a duopoly race between Microsoft and Google. An open-source, self-hostable alternative with Mozilla's brand sits in a completely uncontested lane. If MCP matures into a real standard, Thunderbolt becomes the neutral hub for private AI — potentially more important than the LLMs it proxies.”
“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.”
“Design shops and creative agencies working under NDAs finally have a legitimate option that doesn't route client briefs through OpenAI's servers. The Research and Tasks modes look like exactly what briefing and asset-management workflows need.”
