DotSpider by Nymble
DotSpider is a domain portfolio manager that brings every registrar into one dashboard: renewal alerts, cost forecasts, uptime, SSL and DNS monitoring, and an encrypted vault for your API keys.
Syncs with the registrars you already use
Features
From the first renewal reminder to agency client reporting, DotSpider replaces the spreadsheet, the six registrar tabs, and the calendar reminders.
Alerts that reach you before a card fails or auto-renew quietly switches off.
Email reminders at the thresholds you choose, auto-renew-off warnings, and a Monday digest of what is coming due.
Month-by-month and 12-month renewal spend using your actual registrar prices, with promo-price flags.
A review queue for upcoming renewals: keep, let expire, or mark for sale before the charge hits.
Send renewals, monitoring incidents, and watchlist drops to team channels or signed HTTPS webhooks.
Every registrar, every domain, one dashboard.
Read-only sync with Cloudflare, GoDaddy, Namecheap, Porkbun, Spaceship, and Dynadot, plus RDAP for manually added names.
A 0–100 grade from auto-renew, lock, SSL, DNS, email auth, and expiry, with a fix-it checklist.
Compare renewal pricing across registrars by TLD so you know where moving would save money.
Plan moves between registrars step by step: unlock, auth codes, and a status checklist per domain.
Know when a site goes down, a certificate is about to lapse, or DNS changes unexpectedly.
Uptime checks, SSL expiry warnings, and a history of nameserver and DNS record changes.
SPF, DMARC policy, DKIM selectors, MX, MTA-STS, and BIMI, checked over DNS-over-HTTPS.
Watch domains you want and get notified when they approach expiry or become available.
Rough valuation signals and a public for-sale page per domain with a rate-limited contact form.
Share the right view with the right people, and automate the rest.
A white-label, read-only portal for each client, plus renewal invoice CSVs.
Scoped API tokens, an OpenAPI spec, and REST hooks for Zapier-style automation.
Check any domain you are browsing against your portfolio and add it in one click.
Ask plain-English questions about your portfolio: what expires next, which names have auto-renew off.
List verified domains for sale with Buy Now or Make Offer. First active listing free; $3/mo per additional active listing. Sales: 8% commission ($10 min) via Stripe Connect escrow.
API Key Vault · Pro+
Stop pasting API keys into spreadsheets and password-protected docs. The vault encrypts every secret in your browser before it reaches us.
How we secure your dataHow it works
Paste a read-only API token for Cloudflare, GoDaddy, Namecheap, Porkbun, Spaceship, or Dynadot, or add domains manually. Tokens are encrypted at rest.
DotSpider syncs expiry dates, auto-renew status, DNS, and prices, then scores each domain's health and forecasts renewal spend.
Choose your alert thresholds and channels (email, Slack, Discord, or webhooks) and review keep-or-drop decisions before renewals charge.

Security
DotSpider watches your domains; it does not take the wheel.
Integrations use read-only API scopes. We cannot renew, transfer, or edit DNS with them.
Registrar tokens are encrypted at rest with AES-GCM; vault secrets never leave your browser unencrypted.
TOTP two-factor sign-in, backup codes, and an audit log of sensitive vault activity.

No. DotSpider is a domain portfolio manager by Nymble Digital LLC. You keep domains at your registrars; we sync read-only data and send renewal alerts.
No. New accounts get a 14-day Pro trial without a card. Subscribe in Billing only if you choose to continue on Pro or Portfolio; otherwise you move to the Free plan.
Cloudflare, GoDaddy, Namecheap, Porkbun, Spaceship, and Dynadot sync through read-only APIs. Name.com is on the way. Domains anywhere else can be added manually and enriched with public RDAP data.
Not with default read-only API tokens. Integrations are designed for visibility (expiry dates, auto-renew flags, DNS records), not silent changes.
Registrar tokens are encrypted server-side. The optional API Key Vault (Pro+) uses zero-knowledge encryption in your browser, protected by TOTP two-factor auth, so we only ever store ciphertext.
Pro ($10/mo or $100/yr) covers up to 250 domains across all registrars with daily sync and renewal alerts. Portfolio ($30/mo or $300/yr) adds unlimited domains, up to 5 team members, spreadsheet import/export, unlimited vault keys, and the agency client portal.
Yes. Billing runs through Stripe and you can cancel or switch between monthly and yearly in the customer portal. Your data stays available on the Free plan.
Your first active for-sale listing is free on every plan. Each additional active listing is $3/month (billed as a Stripe subscription quantity, prorated when you add or pause listings). Completed sales still incur an 8% commission with a $10 USD minimum via Stripe Connect.
