SiteWarming vs. a Domain Portfolio Spreadsheet
This is the friendliest comparison we will ever publish, because we give the other option away for free and mean it.
A spreadsheet is usually enough for a small, stable domain portfolio managed by one person. SiteWarming becomes more useful when domains span registrars, data changes frequently, multiple people need access, the ideas behind domains matter, or owners want domains to become visible without building full websites.
Quick decision rule
Here's the thing: a spreadsheet is not the beginner option. It is a legitimate domain management system, and for a lot of people it is the right one. So the decision rule is short:
- Choose the spreadsheet if one person manages a small, stable portfolio and mostly needs to remember renewal dates and costs. We publish a free template for exactly this case, with no email gate.
- Choose SiteWarming if domains sit across registrars, more than one person needs the picture, the data changes faster than you retype it, or you want the domains visible to the world instead of only tracked in a file.
Everything below is the long version of those two sentences.
Side-by-side comparison
| Job | A spreadsheet | SiteWarming |
|---|---|---|
| Cost | Free. Ours literally is: download the template in XLSX or CSV, no email required. (Verified against our own live page, 2026-07-08.) | The asset dashboard and the first three steps (Manage, Launch, Warm) are included; Accelerate is the paid step. Current pricing lives on the pricing page, not here, so it can never be stale on this page. |
| Inventory | Any column you want, maintained by hand. Complete flexibility, zero automation. | One dashboard across registrars. Add domains by hand, by CSV, or by registrar connection. |
| Valuations | A number you look up somewhere else and paste in, dated the moment you paste it. | An estimated value beside each name, kept current without retyping. |
| Collaboration | Shared files work until two people edit at once. Then you have two truths. | One live dashboard everyone reads instead of a file that gets emailed around. |
| Public visibility | None. A spreadsheet is private by nature. That is a feature, until you want the domain findable. | Launch gives a domain a real page and an anonymous contact path; Warm keeps the content current on a monthly baseline. |
| Custody operations | None. Renewals and transfers still happen at your registrar. | Also none, and on purpose. SiteWarming complements registrar and DNS tools; it does not replace registrar custody. |
SiteWarming facts on this page come from the live product page, read 2026-07-08. The spreadsheet has no vendor to cite, which is part of its charm.
Where spreadsheets win
- Free forever. No subscription can compete with zero for a portfolio that barely changes.
- Total control. Every column, formula, and quirk is yours. No vendor decides what a domain record looks like.
- No dependency. The file outlives any company, including ours. It opens in anything, forever.
- Transparent. There is no logic you cannot see. If a total looks wrong, you can click the cell and find out why.
- Instant start. You can have a working system ten minutes from now. Honestly, start there: the template is free.
Where spreadsheets fail
Every failure below is really the same failure: a spreadsheet only knows what someone typed into it, on the day they typed it.
- Staleness is invisible. A renewal price from two years ago looks exactly like one entered this morning. Nothing flags the difference.
- Reconciliation is on you. The file and the registrars drift apart the day after you build it, and closing that gap is a recurring chore nobody assigns.
- Multiple editors fork the truth. Copies get emailed, renamed, and half-updated. Eventually someone asks which file is real, and nobody is sure.
- Values go quiet. A pasted estimate never moves. The portfolio could be appreciating and the file would not know.
- The domain stays dark. This one matters most to us. A perfectly tracked domain is still invisible. No one who might want it can find it or reach you, and the spreadsheet cannot fix that because visibility was never its job.
Where SiteWarming helps
SiteWarming starts where the file stops. The Manage step is the spreadsheet's job done for you: one asset dashboard across registrars, domains added by hand, CSV, or registrar connection, with an estimated value beside each name instead of a pasted number going quietly stale.
Then it does the things no spreadsheet can. Launch puts a real page on a domain with an anonymous contact path, so the right person can find it and reach you without your email address being public. Warm keeps that page's content current on a monthly baseline. Accelerate, the paid step, raises the pace for the domains you decide deserve it. The neutral version of this whole practice is the domain portfolio management guide, and the wider market picture, including tools that beat us at other jobs, is the software comparison.
Portfolio-size breakpoints as guidance, not hard rules
There is no magic domain count where a spreadsheet stops working. The honest breakpoints are about registrars, people, and pace of change, not just size. Read your own row:
| Your situation | Spreadsheet | SiteWarming |
|---|---|---|
| 1 to 10 domains, one registrar, one person, changes a few times a year | Comfortable. This is the spreadsheet's home turf. | Works, but you may not need it yet. |
| 10 to 30 domains, two or three registrars, one person | Workable with discipline. Reconcile against each registrar regularly. | The cross-registrar dashboard starts earning its place. |
| Any size, multiple people need to see or edit the inventory | Fragile. Versions fork, edits collide, one file becomes three. | One shared dashboard instead of a file that gets emailed around. |
| Data changes often: renewals, values, purposes, next actions | Every change is manual, and stale rows look identical to fresh ones. | Estimated values sit beside each name without you retyping them. |
| You want domains visible to the outside world, not just tracked | Out of scope. A spreadsheet has no public face. | Launch, Warm, and Accelerate exist for exactly this. |
If your row is near the top, keep the spreadsheet with our blessing. If two or more of the lower rows describe you, the file is already costing you time it does not show.
Migration steps
Moving from a spreadsheet is deliberately boring:
- 1. Reconcile the file once. Log in to each registrar and fix the rows that drifted. You want to import the truth, not the file's memory of it.
- 2. Save as CSV. If you use our template, the columns already line up. Any spreadsheet with a domain column works.
- 3. Import. The whole portfolio lands in the dashboard in one pass, and estimated values appear beside the names.
- 4. Keep the file. Seriously. It costs nothing, it is your data, and an annual export back to a spreadsheet is a healthy habit no vendor should talk you out of.
Who should stay with a spreadsheet
A clear recommendation, since the whole page has been building to it: stay with the spreadsheet if all three of these are true.
- One person owns the inventory and the discipline.
- The portfolio is small and stable, with changes a few times a year, not a few times a month.
- You do not need the domains publicly visible. Tracking them is the whole job.
That describes a lot of careful owners, and for them a paid dashboard is overhead, not help. Take the free template and spend the money on renewals instead. The moment a second registrar, a second person, or the wish to be findable enters the picture, come back and read the breakpoint table again.

Import your spreadsheet
If you have read this far and the spreadsheet column keeps describing your life, take the free template and go, no hard feelings. If the SiteWarming column does, your spreadsheet imports as a CSV and the whole portfolio lands in one dashboard. The product page shows exactly what that includes.
