InboxZero VS Groundbase

Groundbase's answer:

The API and the MCP server run on Cloudflare Workers, in TypeScript with no backend framework. The database is Turso (libSQL), and billing goes through Stripe. Texts and calls go through Twilio and email through Resend, both on the customer's own accounts, not mine.

The web app is React on Vite, the Windows desktop app is Electron, and the Android app is React Native. All three work from the same cloud data. The MCP server uses Streamable HTTP, and the marketing site is Next.js.

Most of it runs on Cloudflare because of how costs grow. At a flat $19 a month, I can't have a hosting bill that rises with bandwidth on several fronts at once.

Groundbase's answer:

• Groundbase is new and deliberately small: it's used by people running a business of one, like realtors, freelancers and consultants. None of them are "big customers", and I don't list anyone without their permission.

Groundbase's answer:

Two things.

First, it sends things itself, through accounts you own. Texts and calls go through your own Twilio number, campaign email through your own Resend account, card payments through your own Stripe account. You pay those companies directly, on invoices with your name on them, and nothing is marked up.

Second, it has an MCP server. Connect Claude, ChatGPT or Cursor and your assistant can actually do the work in your CRM: "text the three people I quoted last week" ends with three texts sent, not a draft for you to copy.

And it's $19 a month, flat. One plan, one person, every feature included. Nothing is held back for a higher tier.

Groundbase's answer:

Groundbase is built for a business of one, not a sales team scaled down. Most CRMs charge per seat and split the useful parts across tiers and add-ons. Groundbase is one flat price ($19/month or $199/year) with everything included: contacts and deals, tasks and a calendar, invoices and quotes with time tracking, booking links, email and text campaigns, and workflows.

Texting and calling run through your own Twilio account, and campaigns through your own Resend account. You pay those providers directly at their rates, with no markup, and the phone numbers stay yours if you ever leave.

It also works with the AI assistant you already use. Groundbase runs an MCP server with 134 tools, so Claude or ChatGPT can look things up, update records, and draft or send messages in your real account.

It runs on the web, Windows and Android. There's no iOS app yet.

Groundbase's answer:

People running a business of one. A realtor working their sphere, a freelancer, a consultant, a tradesperson, a coach: someone who does their own follow-up and wants the CRM to send the text, the email or the invoice, not just remind them to.

Two things tend to be true of them. They don't want to pay per-seat or team prices for features built for teams, and they're willing to spend fifteen minutes connecting their own Twilio and Resend accounts so they never pay a markup on messages.

It isn't for teams, or for anyone who needs lead routing, permissions or manager reporting. There are better tools for that, and I'd rather say so up front.

Groundbase's answer:

I built the CRM I wanted and couldn't find. Everything out there either assumed a sales team I didn't have, or was the cheap entry tier of someone else's upsell funnel.

The part worth telling is what I removed. Groundbase originally had a credits system: customers topped up a wallet, sent texts through my Twilio account, and I marked up the rate. That was supposed to be platform revenue.

I killed it. Texting compliance for many businesses on one account is brutal for one person to manage, every credits system generates "where did my $10 go" emails, and refunding partial balances is miserable. But the real reason was simpler: I built this to get away from platforms that mark up Twilio, and there I was marking up Twilio. So customers connect their own account now. I lost the markup revenue and got back a product I'd actually buy.
