Superblocks vs Appsmith

Superblocks vs Appsmith, and the open-source platform that does both.

Superblocks leads with Clark, meters AI in Governed Agent Units and offers Hybrid and managed Cloud-Prem deployments. Appsmith is open source, self-hosts free and offers Ask AI plus MCP beta on Business Cloud and Self-hosted Enterprise. ToolJet is open source and generates native apps with its built-in agent or yours.

Choosing a platform

Superblocks or Appsmith: which fits your requirements?

  • Superblocks: Clark-led development and managed operations

    Shortlist Superblocks when you want Clark to build apps and the vendor to manage the platform. Compare app hosting and GAU allowances. Enterprise Hybrid keeps execution in your VPC; managed Cloud-Prem runs the full platform in your AWS environment.

  • Appsmith: open source you operate yourself

    Shortlist Appsmith for free whole-platform self-hosting and a JavaScript-first visual builder. Audit logs are on Business; SAML/OIDC SSO requires Enterprise. Count every builder and end user in your pricing estimate.

  • ToolJet: AI building with Cloud or Self-hosted

    Consider ToolJet for whole-app generation, your own coding agent through MCP and visual editing of native apps. Team includes SSO, audit logs and Git sync; Workflows are Self-hosted only. Compare identical access controls, usage and deployment requirements.

Key takeaways

The short version

  1. AI-first versus open source: you don't have to choose

    Superblocks leads with Clark and meters it in GAUs based on request complexity, on a plan with no free tier. Appsmith is open source and offers Ask AI plus opt-in MCP beta on Business Cloud and Self-hosted Enterprise. ToolJet is open source and generates whole apps with built-in AI or your coding agent, without ToolJet AI credits over MCP.

    • GitHub Copilot
    • Cursor
    • Grok Build

  2. What self-hosted actually means

    Appsmith and ToolJet run the whole platform in your infrastructure from the free tier. Superblocks Hybrid runs only the data plane in your VPC; the control plane, your app definitions and Clark's inference stay in their cloud, and it is Enterprise-only. Cloud-Prem runs the full platform in the customer’s AWS environment, managed by Superblocks. ToolJet offers an air-gapped add-on on Self-hosted Enterprise.

  3. Flat pack, per head, or per builder

    Superblocks is $125 a month for up to 15 builders with unlimited end users, one hosted app and 100 GAUs. Appsmith is $15 per user for builders and end users alike, up to 99. ToolJet bills builders only, includes end users up to the plan limit, and publishes the price of its governed tier.

Pricing

What a team of ten actually pays

Ten builders and ninety end users at published entry or governed-plan rates. Superblocks needs an Enterprise quote for SSO. Appsmith reaches Enterprise at 100 users, so its Business rate is not a quote for this example.

SuperblocksFlat pack

$125 a month, until you need the governed tier.

  • Teams is $125 monthly or $100 annual for up to 15 builders and unlimited end users: the cheapest entry of the three.
  • It includes one hosted app ($10 a month each after that), 100 GAUs that reset monthly, RBAC, staging and production.
  • SSO, audit logs, source control, secrets management and VPC deployment are all Enterprise, with no published price.
AppsmithEvery user billed

$15 a head, and the hundredth user is a cliff.

  • Business is $15 per user per month up to 99 users. Ten builders plus ninety end users requires Enterprise, starting at $2,500 a month for 100 users.
  • SAML/OIDC SSO also requires Enterprise. Google and GitHub OAuth are available on Free and Business.
  • Business includes audit logs and RBAC on cloud or self-hosted; SAML/OIDC SSO requires Enterprise.
ToolJetPer builder, published

$1,990 a month with governance included.

  • Team is $199 per builder per month, billed annually, with SSO, audit logs, Git sync, custom user groups and white labelling: $1,990 for ten builders.
  • Up to 100 end users are included on Team, unlimited on Enterprise, not billed per head.
  • Basic at $29 per builder per month, billed monthly, with 2,000 AI credits, and a free tier below that.
Self-hosting

What actually runs in your network

Two of the three run the whole platform on your infrastructure. One runs an agent.

SuperblocksHybrid or Cloud-Prem

Hybrid for local execution; Cloud-Prem for the full platform.

  • Hybrid runs the on-premise agent in your AWS, GCP or Azure VPC to execute queries and code, on Enterprise only.
  • Configuration, permissions, app definitions and Clark inference stay in Superblocks' cloud, reached outbound-only, so disconnected operation isn't possible.
  • Cloud-Prem runs the full platform, including AI inference, in the customer’s AWS environment, managed by Superblocks. Air-gapped operation is not documented.
AppsmithWhole platform, Apache-2.0

Self-host free; Business for audit logs, Enterprise for SAML/OIDC.

  • Open source under Apache-2.0; the whole platform self-hosts from the free tier.
  • Business adds audit logs and granular access at $15 per user; SAML/OIDC SSO requires Enterprise.
  • Air-gapped deployment is an Enterprise add-on.
ToolJetWhole platform, AGPL-3.0

Everything runs where you put it.

  • Control plane, data plane and app definitions on your infrastructure: Docker, Kubernetes, AWS, Azure, GCP, on-premise from the free Community Edition, with air-gapped deployment through an Enterprise add-on.
  • SSO with SAML, OIDC and LDAP, audit logs and Git sync on Team at $199 per builder per month, billed annually.
  • The Self-hosted Enterprise AI gateway add-on can run locally; fully local AI also requires a supported local model.
AI and coding agents

Who builds the app when you ask

Superblocks builds through Clark and meters AI in GAUs. Appsmith offers Ask AI and an opt-in MCP beta on Business Cloud and Self-hosted Enterprise. ToolJet includes built-in whole-app generation or your coding agent.

SuperblocksChat with Clark

Clark builds, and every build costs GAUs.

  • Clark generates apps from prompts, metered in Governed Agent Units: its documentation gives an 8-GAU dashboard example; Teams includes 100 a month.
  • You pick a mode (Max, Standard or Smart), not a model; Superblocks routes to frontier or open-source models behind the scenes.
  • The Builder MCP lets Claude create, edit and publish apps by conversing with Clark, so agent builds consume GAUs too.
AppsmithAsk AI + MCP beta

Code assistance and an external-agent build path.

  • Ask AI generates JavaScript and SQL in JS modules and queries, self-hosted only, with your own Anthropic, OpenAI, Azure OpenAI or Ollama key.
  • MCP beta lets compatible clients build and edit apps on Business Cloud and Self-hosted Enterprise, after an administrator enables it.
  • Runtime AI uses direct OpenAI, Anthropic and Google AI datasources. The legacy Appsmith AI datasource ended on 30 September 2026.
ToolJetOurs, or yours

Our agent, or the one you already use.

  • ToolJet AI is built in with Luna on Free; Haiku 5.5, GPT, Claude, Gemini and Grok are available on paid plans.
  • Or Claude Code, Codex or any MCP client builds native apps over the MIT-licensed MCP server on Cloud or Self-hosted, without ToolJet AI credits. On Self-hosted, MCP also authors and validates workflow drafts; execution is explicit.
  • Either way the result is a native app you can inspect and edit in the visual builder.

Frequently asked questions

Is Superblocks or Appsmith better for building internal tools?
They optimise for different things. Superblocks leads with Clark on a flat $125-a-month plan with unlimited end users, but has no free tier, meters AI in GAUs, and puts SSO, audit logs and source control on Enterprise. Appsmith is open source and free to self-host, with audit logs on Business at $15 per user and SAML/OIDC SSO on Enterprise; it offers Ask AI and MCP beta on Business Cloud and Self-hosted Enterprise, while workflows remain in open beta. ToolJet combines open source, whole-platform self-hosting from free, built-in whole-app generation or your coding agent, and SSO on a published Team price.
Which is cheaper, Superblocks or Appsmith?
For a team of up to 15 builders with many end users and no governance needs, Superblocks: $125 a month flat, or $100 billed annually, against Appsmith's $15 per user. For a small team, Appsmith: five users are free and ten are $150. For audit logs alone, Appsmith Business has a published $15-per-user price while Superblocks requires Enterprise. SAML/OIDC SSO requires Enterprise on both. ToolJet Team is $199 per builder per month, billed annually, with up to 100 end users and the governance features included.
Can Superblocks and Appsmith be self-hosted?
Appsmith self-hosts the whole platform from the free tier. Superblocks Hybrid, on Enterprise, self-hosts only the data plane: an agent in your VPC executes queries while the control plane, app definitions and Clark inference stay in Superblocks' cloud. Cloud-Prem runs the full platform in the customer’s AWS environment, managed by Superblocks. ToolJet self-hosts the whole platform, on Free, Team and Enterprise, with air-gapped deployment available as an Enterprise add-on.
Which has better AI, Superblocks or Appsmith?
Compare the build paths. Clark generates apps from prompts and its Builder MCP lets Claude build through it, metered in GAUs. Appsmith offers Ask AI snippets and opt-in MCP beta app building on Business Cloud and Self-hosted Enterprise. ToolJet generates whole multi-page apps in-product, with Luna on Free and Haiku 5.5 on paid plans, and lets Claude Code or Codex compose native apps directly without ToolJet AI credits. Evaluate the same app and access controls before choosing.
Do Superblocks or Appsmith work with Claude Code or Codex?
Superblocks' Builder MCP lets Claude create, edit and publish apps by conversing with Clark, which consumes GAUs; its Admin MCP for Cursor, Claude Code and Windsurf administers the org. Appsmith's administrator-enabled MCP beta supports compatible clients, including Claude Code and Codex, on Business Cloud and Self-hosted Enterprise within the key owner's permissions. ToolJet's MIT-licensed MCP server provides native app tools so the agent composes a native app itself on Cloud or Self-hosted. On Self-hosted only, MCP can create and edit workflow drafts, validate them, and run them explicitly or inspect executions; authoring never runs or publishes a workflow automatically. Coding-agent usage and platform costs apply.
Is there an open-source alternative to Superblocks?
Two: Appsmith, under Apache-2.0, and ToolJet, under AGPL-3.0. ToolJet has over 41,000 GitHub stars; Appsmith has around 40,800. Of the two, ToolJet is the one that matches Superblocks on AI app generation, runs the whole platform self-hosted with air-gapped deployment through an Enterprise add-on, and ships SSO, audit logs and Git sync on a published Team price.
Is ToolJet enterprise-ready, and who uses it?
Yes. ToolJet runs in production at Tencent, Swisscom, Duolingo, Gojek, Orange, Unity, ClearScore, Bandwidth, Toss, Endeavour Group, ShareChat and YMCA NYC, among others. It is SOC 2, ISO 27001 and GDPR compliant. Team includes SSO with SAML, OpenID Connect and LDAP, audit logs, Git sync, custom user groups and white labelling. Self-hosted Team includes multiple environments; Cloud requires Enterprise for this feature. Enterprise adds SCIM, custom data retention and a dedicated support manager; air-gapped deployment is a Self-hosted Enterprise add-on.
