Start from a template

Pick a complete application, a single feature, an installable custom service, or an AI configuration tuned to your industry. Every template is versioned, authored, and installs into a working application.

Browse templates
02

Customize extensively

Edit pages visually, add custom modules and fields, fork any page per customer — then bring in a developer and write real code in your own container when the visual layer isn't enough.

For the person who has to defend this choice

Three questions your team will ask. Answered before you're asked.

Choosing a newer vendor over an incumbent is a real decision with real risk. Here's how we've engineered that risk down instead of asking you to ignore it.

"What if we need to leave?"

Your data exports whole

An authenticated export produces your records, files, AI data, vectors, and logs with a manifest and SHA-256 checksums. Platform tables and other tenants stay out; everything that is yours comes with you.

How export works
"What if we outgrow the tooling?"

Hire a developer and keep going

When the visual layer runs out, custom services run in an isolated container behind a declared API contract. Your engineer writes normal code with normal libraries, and the platform validates, authorizes, calls, and logs it.

Read the architecture
"Can we prove what happened?"

Replay any past decision

Authorization isn't just enforced, it's recorded. Any past access decision can be re-derived as it stood at the time and compared against the log, producing an explicit verdict rather than an assurance.

See the audit trail
Accountability

Most platforms log what changed. We log what was seen.

Change history tells you who edited a record. It doesn't tell you who read it, what the AI retrieved, or whether that person was actually allowed to. BuildWithHQ writes all of it to a separate, append-only compliance database that the application cannot rewrite.

Field-level read logging

Revealing an encrypted field is an explicit, refusable operation, and both outcomes are recorded.

Replayable authorization

Re-derive a decision as of then, or under today's rules, and see whether they still agree.

Hash-chained rows

Each entry folds in the previous entry's hash, so a deleted or altered row breaks the chain visibly.

Point-in-time history

Roles, locations, and records keep full version history, so "who could see this in March" is answerable.

Read how replay works
Access log — live sampleappend-only
09:14:02Reveal request · Contact.SSN · j.reyesgranted
09:14:40AI retrieval · 24 records in envelopegranted

09:21:13Export · 1,204 records · m.okaforgranted
09:26:31Replay check · AsOfThenverified
chain intact · prev_hash folded into every row

Illustrative sample. Records a user has no role on never appear in a result set at all, so there is no rejection to log. Refusal is reserved for explicit privileged operations like revealing an encrypted field — and those refusals are recorded with the same weight as successes.

The platform

Visual where it helps. Open where it counts.

Most low-code tools give you speed right up until the first thing they didn't anticipate. BuildWithHQ keeps the visual layer and puts a real escape hatch underneath it, so the ceiling is your budget for a developer rather than the vendor's roadmap.

Visual page editor

Drag and drop pages, or edit the underlying JSON directly.

Custom modules and fields

Add business objects the platform never shipped, with the same security and logging.

Role and location security

One authorization model across modules, APIs, exports, and AI.

Isolated code container

Install specialist libraries that shouldn't run inside a shared platform.

What you get per SaaS app
Your SaaS app
Runtime DB
Compliance log DB
AI & vector DB
Custom domain
Isolated code container

Not a shared database with a tenant column. Three separate databases and a container, provisioned when the app is created — so isolation is something you can point at in a review, not a promise about query filters.

Security model

Permissions that follow the record, not the screen

Most platforms bolt a permission check onto each feature as it ships, which is why the tenth feature always leaks. BuildWithHQ resolves the set of records a user may see once, in a single place, and every read path in the product goes through it — including the ones written after you launch.

Read the security model

Record-level roles

Permissions attach to individual records rather than just to screens. Users can hold several roles at once, and one record can be shared with several roles without duplicating it. Called DataRoles in the product.

Branch and region boundaries

A second boundary alongside roles, for branches, regions, facilities, and territories. The role has to allow it and the location has to match.

Separate read, export, and AI permissions

Being able to open a record doesn't imply being able to export it, or to let the AI read it. Those are three different flags.

Field-level encryption

Sensitive fields are stored encrypted, fall out of search and AI retrieval automatically, and every reveal is logged.

One page, three versions
Base page — published by you
Every customer gets this until they change it.
Northwind's fork
They added two fields and reordered the panel themselves.
Contoso's fork
Different layout entirely. Your next release still reaches them.

A fork records what it changed, so when you publish an update the customer can see the difference and adopt it — or stay put, and roll back if they change their mind.

Per-tenant forking

Let customers make their own small changes

Most of your support queue is people asking for a field to move, a column to be added, or a panel to be reordered. On BuildWithHQ, the customer can fork their own page and do it themselves — without branching your codebase, without a ticket, and without breaking anyone else's version of that page.

Fewer support tickets

Small layout requests stop reaching you at all.

Safe to undo

Version history per fork, with rollback to the base page.

No downstream regressions

One customer's edits never touch another customer's page.

Or bill for it

Builder-authored custom work is tracked as a sellable, entitled item.

How forking works
Data ownership

The exit is documented on the way in

Lock-in is a business model, not a technical necessity. Both you and the companies using your app can export everything, whenever they want, without asking anyone's permission.

Records and files

Your business data and every uploaded file, packaged together rather than as a CSV that loses the attachments.

AI data and vectors

Embeddings and AI knowledge come with the export, so the work you put into training context isn't stranded.

Your log history

The compliance trail exports too. Your audit history is yours, not a record we keep and you rent.

Manifest and checksums

A manifest plus SHA-256 checksums, so you can verify the package is complete and unaltered on arrival.

Read the export documentation Scoped per account. Other tenants' data and platform secrets are never included.

Browse the build guides
Installable custom services

Install a custom service once, then call it from anywhere in your app

An installable custom service is a real service running in its own container — document processing, a specialist model, an industry calculation, anything that doesn't belong in a visual builder. It arrives as a signed, versioned package, declares the endpoints it exposes, and from then on your pages, workflows, and AI actions call it like any other endpoint. In the product these are called appliance endpoints.

How custom services work

Signed and fingerprinted

Publisher signatures, image digests, SBOM references, and a release fingerprint on every version. You know exactly what is running.

Declared network access

A package states what it needs to reach. Sealed packages reach nothing at all, and the manifest is authoritative.

Validation before publish

Versions can't be listed until they pass validation, and a bad release can be revoked without waiting for anyone to uninstall it.

Every invocation recorded

Request and response hashes, outcome, duration, package version, and the code identity frozen at call time.

The same infrastructure runs the marketplace. If you build something worth reusing, you can publish it as a product with versions, offers, and pricing, and the platform handles checkout, entitlements, and payouts. If someone else already built it, you buy it and install it.

What your users get on day one

The features that make people actually open the app

These aren't add-ons you build later. They ship with every application, permission-aware from the start.

AI insights

Surfaced observations drawn from records the user is already allowed to read. An insight generated from a record you can't see never reaches you — the permission is inherited from the source, not applied afterward.

What's new

A per-user feed of what changed since they last looked, so the answer to "did anything happen while I was out" takes five seconds instead of a scroll through six modules.

Favorites

Pin the records and pages someone works from every day. If their access to a record is later revoked, it disappears from their favorites automatically — the shortcut can't outlive the permission.

Universal inbox

Email, SMS, web leads, and internal messages land in one place. Every conversation is a platform record, so it inherits the same permissions, custom fields, and logging as everything else.

ActiveWorkplace

Pin any record and turn its permitted recursive graph into a live workplace for people, GoClaws and workflows, with stale-work detection and Graph Playback.

Workflows and automation

Automate the work that happens between the screens

Most of what a business application does isn't a form — it's the follow-up that should have gone out on Thursday, the approval nobody chased, the status that should have flipped when the invoice cleared. Workflows run that work in the background, on the same permission model as everything else.

Read the workflow guide

Steps that do real work

Send an email or SMS, update a record, call an external API, run an AI action, wait for a date, branch on a condition, or stop and require a human approval before anything else happens.

Editing a live workflow is safe

Changing an automation doesn't rewrite the runs already in flight. A new version is created, new work moves to it, and everything currently running finishes on the definition it started with.

Nothing runs twice

Background workers lease each job before touching it, so two servers can never pick up the same step. Failures retry on a schedule instead of disappearing silently.

Reporting stays inside the rules

Managers can see run history, failure rates, and cycle times without that reporting view becoming a side door around record permissions.

Integrations

Connect to everything outside the platform, in both directions

No business application lives alone. Your app can call out to other systems, accept calls and webhooks coming in, and expose selected capabilities to your own customers and partners — without a single credential or security decision ending up in the browser.

Read the integration architecture

Outbound calls

Trigger an external API from a page action, a workflow step, a scheduled job, an AI action, or a background process.

Inbound endpoints and webhooks

Accept authenticated requests and provider callbacks, map the payload onto your records, and start work from them.

Credentials stay server-side

Secrets are referenced through approved mappings. The front end never holds a key and never decides what it can reach.

Queues, retries, idempotency

Rate limits, retry policy, and duplicate protection are part of the integration layer, not something each connection reinvents.

Why BuildWithHQ

2

An escape hatch

When the visual layer runs out, your developer writes real code in an isolated container.

3

Evidence, not assurance

Past authorization decisions are replayable and produce a verdict, not a reassurance.

Six kinds of team, one platform underneath

The common thread isn't company size. It's needing an application specific enough that packaged software doesn't fit, and accountable enough that a weekend project won't do.

Corporate departments

The system nobody sells you

Every department eventually runs on a spreadsheet that has outgrown itself. Build the actual application, with the audit trail and permission model your security team will ask about, without waiting eighteen months for central IT.

Common questions

Questions we get before people sign up

Is BuildWithHQ low-code or a development platform?

Both, on purpose. Pages, data models, workflows, and permissions are built visually, so most of an application takes days rather than months. When you hit something the visual layer can't express, you write real code in an isolated container and the platform calls it through a declared API contract. You don't have to choose one and live with the ceiling.

Do I get my own database, or is it shared with other customers?

Every application you create is provisioned with three dedicated databases — a runtime database, a compliance log database, and an AI and vector database — plus an isolated container for custom code. Isolation is a physical boundary you can point to in a security review, not a filter applied to a shared table.

What happens to my data if I leave?

You export it. An authenticated export produces your records, uploaded files, AI data, vectors, and log history, packaged with a manifest and SHA-256 checksums so you can verify nothing is missing or altered. Other tenants' data and platform secrets are excluded. Your customers can export their own data the same way.

Can I hire a developer to extend it?

Yes, and that's the intended path for anything specialized. Your developer writes normal code with normal libraries, packaged as an extension that runs in its own container. The platform validates the contract, enforces permissions, calls the endpoint, and logs the invocation — so bringing in an outside contractor doesn't mean widening your security boundary.

What exactly gets logged?

Reads, not just writes. Encrypted-field reveals, AI retrievals, exports, and the authorization decision behind each one are written to a separate append-only database that the application cannot rewrite. A reveal that is refused is recorded with the same weight as one that succeeds.

Records a user has no role on are a different case: they never enter a result set, so pages simply load with what that person can see. There is no access-denied event because there was no attempt to deny — and that leaks less than an error would, since a refusal confirms a record exists.

Past decisions can also be replayed: the platform re-derives the access envelope as it stood at the time and compares it against what was logged, returning an explicit verdict rather than an assurance.

Can my customers customize their own screens?

Yes. A customer can fork a page and change it for themselves — reorder a panel, add fields, adjust the layout — without branching your codebase and without affecting any other customer's version of that page. Forks keep their own version history and can roll back to the base page. When you publish an update, the customer sees what changed and chooses whether to adopt it.

How is this different from Bubble, Retool, Xano, or Airtable?

Those tools are strong in a focused layer — a front end, an internal tool, a backend, a database. BuildWithHQ combines the backend, the customer-facing application, CRM, inbox, calendar, workflows, permissions, billing, templates, and AI into one product, aimed specifically at people building multi-tenant SaaS they intend to resell. There are detailed, honest comparisons against more than forty platforms, including cases where the other tool is the better answer.

Can I resell applications to my own customers?

That's the core model. You pay a flat monthly subscription, and the platform takes a share of what you charge your customers, collected and paid out through Stripe Connect. Tenant provisioning, custom domains, per-customer billing, and entitlements are built in rather than assembled.

How much does it cost?

A flat monthly subscription plus a share of builder-to-customer revenue. Plan tiers are being finalized ahead of public launch, and nothing is charged while your application is still in development.

Can I evaluate it before creating an account?

All of it. The full builder console preview runs to sixty-nine pages with realistic data, the documentation covers every module and every error code the platform can raise, and the technical architecture reference is downloadable as a PDF. None of it requires a sign-in.
