Butterbase
Agent-native backend that lets Claude Code, Codex or Cursor run your CRM, intake, invoicing and client portal under backend-enforced rules.
The differentiator is backend-enforced policy, not the AI branding — refund caps and access rules applied in the substrate can't be prompt-injected away, and that's the part worth paying for. For a small firm whose real pain is five tools that don't share context, $19/mo Launch puts one live app in front of real users with no per-seat tax. Skip it if your workflows are genuinely bespoke, you need HIPAA on a budget (that add-on is Enterprise-tier), or you want to own the infrastructure.

Skip Butterbase if you need a BAA or SSO on a sub-$100/mo budget — the HIPAA add-on, SOC 2 report and single sign-on are Enterprise-only, so a compliance-sensitive practice ends up in a sales conversation rather than on the $90/mo Certified tier.
Storage beyond your tier bills at $0.125/GB and bandwidth at $0.09/GB on paid plans, so a document-heavy client portal can add cost in the first busy month
$19/mo Launch is priced to beat a $462/mo Copilot Professional seat-based bill at ten internal users — Butterbase's own August 2026 breakdown makes that comparison for client portals. Certified at $90/mo undercuts most per-seat CRM stacks for a ten-person firm. Above that, Enterprise is custom; compare against Supabase or a no-code suite only if you already have an engineer who can own the backend.

About Butterbase
Butterbase is an agent-native backend for running a service business. Rather than stitching a CRM, intake forms, client portal, support queue and invoicing across five vendors, you get one shared customer record plus a rulebook the backend itself enforces. Your existing AI assistant — Claude Code, Codex, Cursor, Windsurf, GitHub or Cline over MCP — reads and writes directly against auth, database, storage and edge functions, so an agent can build and ship a client portal in a session. Where it differs from other agent tooling is where policy lives. Refund caps, access rules and approval flows are applied in the substrate, so an agent attempting a $600 refund against a $500 cap gets blocked rather than argued out of it in a prompt. Ready-to-fork recipes cover client portal, CRM, intake, invoicing, follow-up and support, and they inherit your customer records the moment you fork them. An AI Gateway routes Claude, GPT, Gemini, Seedance and Llama through one API key with rate limits, budgets and a unified usage log. It is aimed at law practices, consultancies, agencies, real estate teams, accounting firms and security providers — published case studies include MT Law LLC, Veta Insights, Payne Sharply Luxury Realty and Sphere, two of which note there is no engineer on staff. SOC 2, GDPR, row-level security and encryption ship by default; single sign-on and a HIPAA add-on sit on Enterprise. Since September 2026 it has also been a selectable backend inside Dyad and an extension inside Qoder, alongside its MCP connectors.
Behind the Verdict
Butterbase sits deliberately between no-code tools that hit a customisation ceiling and pure vibe coding, which it argues produces frontends fine and backends badly — a point it makes at length in its own "Why AI Coding Agents Fail at Backends" writeup. The architecture backs the claim up. Agents connect over MCP to auth, database and logic natively rather than generating a backend from a prompt, and the managed substrate carries SOC 2, GDPR, row-level security and encryption by default. Strengths worth naming. The MCP surface is broad and current: Claude Code, Codex, Cursor, Windsurf, GitHub and Cline, plus backend integrations for Dyad (via Plugins) and Qoder (via Extension management), both announced in October 2026. Recipes for intake, CRM, invoicing, follow-up and support are genuinely fork-and-go — the marketing claim is fork-to-live in under 30 minutes on a custom domain, and the Payne Sharply case study has a broker with no engineers building a listing page and CRM in an afternoon. The AI Gateway routing Claude, GPT, Gemini, Seedance and Llama through one key with budgets and unified usage logs is a real convenience if you're paying several model vendors. And the no-per-seat pricing matters for a firm that expects to add staff. Weaknesses. The abstraction is the product and also the ceiling — you cannot take full control of the infrastructure, and deeply bespoke intake or billing logic will run into the substrate's shape. Quotas are modest on the entry tiers: Playground gives 500 MB database and 1 GB file storage, Launch 4 GB and 50 GB, and paid plans bill overage at $0.125/GB storage and $0.09/GB bandwidth, so a document-heavy practice should model that before committing. AI usage is credit-based rather than unlimited — $1 one-time on Playground, $5/mo on Launch, $15/mo on Certified. Free projects pause after one week of inactivity, which makes Playground a try-it tier, not a hosting tier. SSO, the SOC 2 report, the uptime guarantee and the HIPAA add-on are all Enterprise-only, which is awkward for a law firm that needs a BAA on day one — Butterbase's own August 2026 post acknowledges a possible BAA narrows the shortlist early. Where it fits: a five-to-twenty person professional services firm with no engineer, currently running email, a shared drive and a billing tool, that wants one record and agents that can act on it safely. Where it doesn't: an engineering-led team with an integrated stack (this is a step sideways), a firm whose workflows are the differentiator, or a genuinely document-heavy operation that will blow past tier storage and bandwidth.

Real-world workflow fit
Concrete scenarios for the personas Butterbase actually fits — and what changes day-one when you adopt it.
Fork the intake and client portal recipes, connect them to Gmail and Stripe over MCP, then have your Claude Code session customise the fields to match your matter types.
Outcome: Client intake, case notes and billing land in one record your agent can draft updates from, and refund or access actions are blocked by the substrate when they breach your caps.
Use a single prompt to generate a listing page plus a simple CRM, point the intake form at lead routing, and publish to a custom domain on Launch.
Outcome: A live listing page and working CRM the same afternoon, updated through a form rather than a deploy — the Payne Sharply pattern.
Store tickets, evidence and audit logs under row-level security in one project, with the AI Gateway routing model calls through one key with budgets and a unified usage log.
Outcome: One backend to evidence controls from, instead of reconciling five vendors' logs at audit time.
Use Cases
- Consolidate CRM, intake, invoicing and client portal for a consultancy into one shared record
- Run client support agents that are blocked by backend policy from exceeding refund caps
- Build a custom client portal for a law firm without writing backend code
- Route Claude, GPT, Gemini and Llama calls through one API key with budgets and a unified usage log
- Fork a follow-up recipe to run automated outreach and status updates
- Stand up a live listing page and simple CRM for a real estate team in one afternoon
- Keep case notes, intake and billing in one record that agents can read and write
- Give a compliance team one backend where tickets, evidence and audit logs sit under their own rules
Models Under the Hood
as of 2026-10-18
Limitations
- Butterbase abstracts the backend, which limits how far you can customize for deeply bespoke workflows or take full control of infrastructure.
- Lower tiers carry modest storage and bandwidth — Playground gives 500 MB database and 1 GB file storage, Launch 4 GB and 50 GB — with overage on paid plans billed at $0.125/GB for storage and $0.09/GB for bandwidth.
- AI usage is credit-based rather than unlimited: Playground includes $1 of AI usage as a one-time allowance, Launch $5/mo, Certified $15/mo.
- Free Playground projects are paused after one week of inactivity.
- Single sign-on, the SOC 2 report, the uptime guarantee and the HIPAA add-on are available only on Enterprise, so a firm needing a BAA has to negotiate rather than self-serve.

What this tier adds
Raises to 10 projects, 8 GB database, 100 GB storage, 250 GB bandwidth, 100,000 monthly active users and $15/mo of AI usage
Enterprise
Custom
Ideal for
Regulated practices and larger firms that need SSO, a SOC 2 report, an uptime guarantee and a HIPAA add-on

Where the pricing makes sense
The company stage and team size where Butterbase's pricing actually pencils out — and where peers do it cheaper.
$19/mo Launch is priced to beat a $462/mo Copilot Professional seat-based bill at ten internal users — Butterbase's own August 2026 breakdown makes that comparison for client portals. Certified at $90/mo undercuts most per-seat CRM stacks for a ten-person firm. Above that, Enterprise is custom; compare against Supabase or a no-code suite only if you already have an engineer who can own the backend.
Setup time & first value
How long it actually takes to get something useful out of Butterbase — broken out by persona, not the marketing-page minute.
Non-technical founder: under 30 minutes from forking a recipe to a live app on a custom domain, since the free Playground needs no card. Agent-assisted builder: a single Claude Code or Cursor session to wire auth, database and logic over MCP. Compliance-sensitive firm: budget longer, because SSO, the SOC 2 report and the HIPAA add-on are Enterprise-tier and need a conversation first.
Switching to or from Butterbase
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a five-tool stack (CRM + forms + portal + support + invoicing): fork the matching recipes so they inherit your customer records, then import contacts into the shared record
- →From Claude Code or Cursor alone with a hand-rolled backend: install the Butterbase MCP connector so your agent talks to managed auth, database and logic instead
- →From Dyad: switch the backend to Butterbase via Plugins to get Postgres, logins, row-level security, storage, AI gateway and search
- →From Qoder: install the Butterbase extension from Extension management and authorise it in Connectors for a queryable Postgres backend
- ↗To self-hosted Supabase: export the Postgres schema and data, then rebuild auth and row-level security policies yourself since the substrate abstraction doesn't travel
- ↗To a per-seat CRM suite: export the shared customer record to CSV and expect to re-implement the backend policy guardrails as workflow rules
- ↗To an engineering-led stack: re-implement auth, storage and edge functions in-house, accepting that backend-enforced policy must be coded rather than inherited
