v0.3.1 — Launch ready

Released: 2026-07-08

This is the first version of Krexel that we consider production-ready for paying customers. Every feature documented on the website now works end-to-end.

What works

• End-to-end deploys — signup, deploy, R2 file storage, Cloudflare Pages build, custom domain, SSL, all verified
• Patch deploys — your AI can edit the live site in 8 seconds via the MCP server
• Rollback — one command to revert to any previous deploy
• Custom domains — GoDaddy, Cloudflare, Namecheap, and any other DNS provider
• Stripe billing — live mode, $10/$25/$50 tiers, webhook handling tested
• API — every endpoint documented, 170 tests pass
• Marketing site — full SEO foundation (sitemap, JSON-LD, OG images)

Added

• Stripe live mode — real payments wired through Krexel's own Stripe account
• Patch deploys — single-file edits to the live site without full rebuild
• R2 file tree storage — every deploy's file tree is stored in Cloudflare R2, enabling patch/rollback flows
• Custom domain support — connect any domain via DNS records
• Self-healing auth — legacy API keys auto-backfill the new token-sha256 index on first use
• /readyz deep probe — opt-in KV round-trip check (use ?deep=true to verify writes)
• SEO foundation on the marketing site — sitemap, robots, JSON-LD structured data, PNG OG image
• Auto-deploy from GitHub — push to main deploys to Vercel automatically
• Eight reference docs — getting-started, install-cli, install-mcp, connect-custom-domain, dns-godaddy, dns-cloudflare, dns-namecheap, billing-and-plans

Changed

• /readyz no longer probes KV by default — saves 3 KV ops per call; use ?deep=true for the round-trip check
• Auth flow uses sha256 token index — O(1) lookup instead of O(n) scan

Fixed

• R2 was wired read-only — the deploy route now writes the file tree to R2 on every deploy
• Pages manifest field rejected with 8000096 — switched from Blob to string in the multipart form
• OG image was SVG, invisible on social — replaced with 1200×630 PNG
• /sitemap.xml returned 404 — added Next.js dynamic sitemap
• /robots.txt was missing — added declarative robots config
• No structured data on the homepage — added JSON-LD for SoftwareApplication, Organization, WebSite, FAQPage

Security

• Secrets backed up to ~/.hermes/credentials/ before every wrangler secret put
• Tokens never logged — even in verbose mode
• MCP server scopes per-tool — deploy tool can't read keys, patch tool can't deploy

Known limitations

• No team seats yet — Studio tier pricing is published but team-seat feature isn't wired up. Pricing page has been updated to reflect this.
• KV free tier — daily limit resets at 00:00 UTC. We'll move to paid tier when we exceed it consistently.
• No in-dashboard onboarding tour — first-run experience uses the existing progress checklist. Improved tour coming in v0.4.
• Test customers + Pages projects in KV — cosmetic, not affecting production. Will purge post-quota-reset.

Next: v0.4

• Team seats (Studio tier)
• Onboarding tour for first-time users
• Deploy progress bar (replaces static status pill)
• Deploy success celebration modal
• /blog/ and /changelog/ with weekly content
• Logo redesign (commissioned)

Thanks to everyone who tested, filed issues, and pushed us to ship. Let's go.
