- Base44 (owned by Wix) builds apps, websites and AI agents from a prompt, with a database, logins, roles, Stripe, scheduled workflows and code you can sync to GitHub.
- Bob is an AI coworker who builds small internal apps when the job needs one, hosted for you and private to your workspace by default.
- Base44's connectors, workflows and backend functions start on its Builder plan at $50/mo. A Bob app can use your 3,200+ connected apps on any plan.
- On every Base44 plan except Enterprise, its docs say your data “can be used to train AI models.” Bob never uses your data for training.
- Keeping a Bob app running costs about $3 a month in credits if your team uses it a few hours each workday, and about $15 if it is busy around the clock. And it can use the 3,200+ apps your team already connected to Bob from day one.
- Building a customer-facing app with roles and payments? Base44 is further along. Want the tool to come from the coworker already doing the work? That is Bob.
What Base44 is
Base44, owned by Wix, invites you to “build your own apps, websites, products and AI agents on Base44 using your own words.” You build in a chat (with a Discuss mode), adjust in a visual editor, and on Builder and up edit the React code, pick your model, and sync with GitHub.
Apps get a database, logins (email, Google, Microsoft, Apple, Facebook), Admin and User roles plus custom ones, file storage, Stripe, email, backend functions and scheduled workflows. It lists 47 connectors, including Slack, Gmail, HubSpot, Salesforce and QuickBooks, and SOC 2 Type II and ISO 27001.
What Bob is
Bob is an AI coworker. Your team asks him for work in Slack or in the HeyBob app for Mac, Windows and Linux, and he does it across the 3,200+ apps you connect: the report, the follow-up email, the update in the CRM. Writes wait for an Approve button by default, and every finished job posts a receipt with what it cost.
Sometimes the job is a small tool, and then Bob builds it. Ask for an expense tracker or a request board and he builds a small web app with its own database, hosts it at its own address, and keeps it private to your workspace unless you say otherwise. If the job is a view of numbers you already have, he builds a page instead, which costs nothing to keep.
Two ways to get an internal tool
Base44 is the app builder that leans hardest into internal tools: it sells to “every department,” and it can build agents into the apps it makes. You open Base44, describe the tool, refine it, connect your apps and publish. Someone on your team owns that app and its plan.
With Bob, the tool comes from the coworker who is already doing the work. Your team asks him for reports and follow-ups in Slack or the HeyBob app, and your tools are already connected under each person's own access. When a job needs a tracker, he builds it in the same thread, hosts it, and keeps working around it. The tradeoff is depth: Base44 apps can have roles, payments and logins for outsiders today, and Bob's cannot yet.
Use the data you already have
Most app builders start you from an empty database, then ask you to wire up connectors, keys or server code to reach your business data. With Bob, that part is already done. Your team connects its tools to Bob once, by asking (“connect HubSpot”), pressing Connect and signing in, and 3,200+ apps are on the menu.
When Bob builds an app, it can read those same tools, and write to them if you allow it, through the connection of the person who asked for it. That person approves each tool before the app goes live. Your Google Sheets, HubSpot deals or Gmail are in the app on day one, with no keys or server code. Base44 has connectors too: 47 of them, available from its Builder plan.
What it costs to keep an app running
Bob’s apps are billed in the same credits as the rest of his work: 30 credits a day to keep an app, plus 10 for each hour it is awake. When nobody is using it, it sleeps. At the entry plan’s rate ($75 for 40,000 credits), that works out like this:
| How much your team uses the app | Credits a month | In dollars |
|---|---|---|
| Opened now and then | About 1,000 | Under $2 |
| A few hours each workday | About 1,560 | About $3 |
| Busy around the clock | About 8,100 | About $15 |
Those credits come out of the workspace plan you already have, which is $75 a month (half price through December 31, 2026) and covers everything Bob does. So an app is a small slice of an existing bill, not a new subscription. If an app builder is all you want, Base44 costs less to start.
On Base44, a private app needs a paid plan, and connecting it to your business tools needs Builder, from $50 a month ($40 billed yearly). Hosting is included. What the running app does, like sending email, calling AI or running workflow steps, uses integration credits, and when they run out the app’s actions stop until the next reset.
Side by side
What Bob’s apps do not do yet
We would rather you hear the limits from us than find them after you build.
- An app does not know who is using it yet. So there are no per-person views, roles or approvals inside an app.
- No custom domains, file uploads, payments or email sent from an app yet.
- No code export. Bob owns the build: you describe the change, he makes it.
- Signing in to a private app goes through Slack today. Teams on the HeyBob app without Slack can use public apps.
- A sleeping app takes a couple of seconds to wake up.
Which one should you pick?
Pick Base44 if…
- You want a customer-facing app with roles, Stripe payments and your own domain.
- You want to own the React code and keep it in GitHub.
- You need SOC 2 Type II and ISO 27001 paperwork today, or an IP allowlist and data region choice.
Pick Bob if…
- You want the tool to come from the coworker who already does the work around it.
- Your apps should use your connected tools on any plan, under a real person's access.
- You want a guarantee your data never trains anyone's AI, without an Enterprise contract.
- You would rather keep one workspace bill than add a builder subscription.
Both can build an expense tracker in an afternoon. The real question is whether you want an app builder your team learns, or a coworker who builds the tool and then keeps doing the work.
Fair questions
Is Bob a good Base44 alternative?
For small internal tools, yes: ask Bob in Slack or the HeyBob app and he builds, hosts and changes the app for your team, then keeps doing the work around it. If you need roles, payments or logins for outside users, Base44 does that today and Bob's apps do not yet.
Can I export the code of an app Bob builds?
No. Bob keeps the code and changes it when you ask. Base44 offers GitHub sync and a zip download from its Builder plan.
How do the prices compare?
Base44 runs from $20 a month (Starter) to $200 a month (Elite), with connectors, workflows and backend functions starting on Builder at $50. Message credits pay for building and integration credits pay for what the running app does. Bob is one workspace fee from $75 a month for 40,000 credits that cover everything he does; an app he hosts costs 30 credits a day plus 10 for each hour it is awake.
Does either one train AI on my data?
Bob never uses your data, prompts or connected-tool content to train AI models. Base44's privacy documentation says data on every plan except Enterprise can be used to train AI models.
What happens when credits run out?
On Base44, actions in your app pause until credits reset, and app users see an error. On Bob, a workspace that runs out of credits has its apps paused with their data kept, and they come back when credits do.
