- Replit is a full software platform: its Agent builds apps in a real codebase you can export, with managed Postgres, several hosting options, Stripe and Git sync.
- 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.
- A private Replit app makes every visitor sign in with a Replit account. A private Bob app opens for your workspace members.
- Replit Core is $20/mo for up to 5 builders and Pro is $100/mo, with hosting drawn from the same credits. Bob is one workspace fee from $75/mo.
- 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 software you will keep extending? Replit is the stronger platform. Need a tracker for your team today? Bob gets there with one message.
What Replit is
Replit calls itself “the AI platform that helps you turn your ideas into real outcomes.” You build by chatting with its Agent, with a visual editor, a design canvas and a full code editor and shell. You can pick the model, download the code, and sync it both ways with GitHub.
Apps get managed PostgreSQL with separate development and production databases, Replit Auth or Clerk logins, file storage, Stripe, and four kinds of deployment, including always-on VMs and scheduled jobs. Replit lists 100+ integrations, among them Slack, Gmail, HubSpot and Salesforce, and holds SOC 2 Type 2.
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.
A platform you build on, or a coworker you ask
Replit is where you build software you mean to keep: a real codebase, real environments, real hosting choices. Someone on your team owns the project and how it runs. That is the right shape when the app is the product, or when it will grow into one.
Bob starts from the work. Your team already asks him for reports and follow-ups in Slack or the HeyBob app, and your tools are already connected. When a job needs a small tool, he builds it in the same thread, hosts it, and keeps doing the work around it. There is no project to run and no hosting to choose. The tradeoff is depth: Bob's apps are small internal tools, not software you extend yourself.
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. Replit lists 100+ integrations (73 named in its docs), most of them from its Core 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, Replit costs less to start.
On Replit, you start with Core at $20 a month, then the deployment draws on your credits: Autoscale from about $2 a month plus usage, or a Reserved VM from $15 to $130 a month. And everyone who opens a private app needs a Replit account.
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 Replit if…
- You are building software you will keep extending, alone or with engineers.
- You want a real codebase in GitHub and a choice of how it runs, from autoscale to dedicated VMs.
- You need Stripe, logins for outside users, or apps on the iOS App Store.
Pick Bob if…
- You need a small tool for your team, not a codebase to maintain.
- Your teammates should open private apps without making a separate account.
- You want one coworker who builds the tracker and keeps doing the work around it.
- You would rather keep one workspace bill than add a platform subscription and hosting.
Plenty of teams will use both: Replit for the software they build, Bob for the tools and busywork around the company.
Fair questions
Is Bob a good Replit alternative?
For small internal tools, often yes: ask Bob in Slack or the HeyBob app and he builds, hosts and changes the app for your team. For software you mean to extend, no. Replit's codebase, hosting choices and outside-user logins are well beyond what Bob's apps do.
Can I export the code of an app Bob builds?
No. Bob keeps the code and changes it when you ask. Replit gives you the full codebase, a zip download and GitHub sync.
Do my teammates need an account to open the app?
On Replit, private apps ask visitors to sign in with a Replit account. A private Bob app opens for members of your HeyBob workspace after they sign in, which today goes through Slack.
How do the prices compare?
Replit Core is $20 a month for up to 5 builders and Pro is $100 a month for 15 builders and 50 viewers, with Agent work and hosting drawn from one credit pool. 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.
Which one has more security paperwork?
Replit lists SOC 2 Type 2 and is working toward ISO 27001. HeyBob's SOC 2 Type 1 is in progress with no target date yet. Every Bob app gets its own separate database, and your data is never used to train AI models.
