Caldera vs Conduit vs Gelato: Rollup-as-a-Service and Appchain Comparison

Appchains Are a Strategic Commitment

Launching a dedicated rollup or appchain is not just a developer decision. It changes how users bridge assets, how liquidity forms, how the product is monitored, how fees are managed, how upgrades happen and how security assumptions are explained.

Caldera, Conduit and Gelato are all relevant providers in the Rollup-as-a-Service and appchain infrastructure category. They overlap in some areas, but each is strongest for a different buyer profile.

This comparison focuses on buyer fit for Web3, gaming, DeFi, RWA and application teams that are deciding whether to launch on an existing network or operate dedicated chain infrastructure.

Quick Comparison

| Provider | Strongest fit | Less ideal when | Buyer should verify | |---|---|---|---| | Caldera | Teams that want custom rollups and interoperability across a rollup ecosystem | Teams that only need a simple deployment on an existing L2 | Rollup stack, Metalayer routes, bridge assumptions, app support, chain launch process | | Conduit | Teams that want complete chain infrastructure with rollups, RPC, indexing and marketplace tooling | Teams that want only one narrow module without a broader platform | Supported stacks, node uptime, indexing, marketplace apps, data availability, sequencer model | | Gelato | Teams that want appchain infrastructure connected to automation, relaying and Web3 cloud services | Teams that want a pure rollup vendor with no adjacent automation or relayer needs | Supported chains, rollup stack, account abstraction, relay, automation, monitoring and pricing |

Short Answer

Choose Caldera if interoperability and custom rollup deployment are central to the strategy.

Choose Conduit if you want a complete chain infrastructure platform with RPC, indexing and rollup operations in one place.

Choose Gelato if the appchain is part of a broader Web3 cloud architecture involving automation, relaying, account abstraction or developer infrastructure.

Caldera: Best for Custom Rollups and Interoperability

Caldera is known for Rollup-as-a-Service and its Metalayer interoperability work. Its documentation describes Metalayer as an interoperability system for a rollup-centric world, with bridge aggregation, omnichain tokens and shared liquidity across connected networks. Its Rollup Engine materials describe app-specific rollups deployed across frameworks such as Arbitrum Nitro, Optimism Bedrock, ZK Stack and Polygon CDK.

Caldera may fit:

• applications that want a dedicated rollup
• gaming, social or DeFi products needing custom execution
• projects that care about day-one interoperability with other rollups
• ecosystems that want multiple chains connected through common infrastructure
• teams that want rollup launch support rather than internal chain operations

Caldera’s main value is not only launching a rollup. It is the combination of dedicated blockspace and an interoperability thesis through Metalayer. This matters because one of the biggest appchain problems is fragmentation. A chain with no liquidity, users or bridge clarity can become an island.

Questions to ask Caldera:

• Which rollup frameworks are supported for mainnet?
• What interoperability routes are available through Metalayer?
• Which bridges, solvers and message-passing systems are used?
• What is the sequencer model and upgrade process?
• What happens if we later migrate infrastructure or change stack choices?
• How are monitoring, incident response and chain support handled?

Conduit: Best for Complete Chain Infrastructure

Conduit positions itself as a complete chain infrastructure platform. Its public documentation describes rollup deployment, RPC nodes, indexing and marketplace tooling. Conduit also operates RPC infrastructure for many rollups and offers multi-chain access, autoscaling RPCs, performance monitoring and access controls.

Conduit may fit:

• teams launching production rollups
• apps that need RPC and indexing alongside the chain
• ecosystems that want tooling and integrations from a marketplace
• projects that want fewer infrastructure vendors
• teams that need operational dashboards and performance visibility

Conduit’s main strength is breadth across the chain operations layer. Instead of treating rollup launch, RPC and indexing as separate procurement decisions, Conduit gives buyers a platform view.

That breadth is useful, but buyers should still ask what is native to Conduit, what is partner-powered and what remains the buyer’s responsibility.

Questions to ask Conduit:

• Which rollup stacks are supported today?
• What RPC uptime and performance commitments apply?
• What indexing products are included or optional?
• Which marketplace apps are production-ready?
• How does pricing scale with chain usage?
• How are upgrades and emergency patches handled?

Gelato: Best for Appchain Infrastructure Connected to Web3 Cloud Services

Gelato is relevant where appchain infrastructure connects with automation, relay, account abstraction and Web3 developer services. For many teams, launching a chain is not the only problem. They also need gasless transactions, scheduled transactions, account abstraction, relaying, offchain triggers and operational tooling.

Gelato may fit:

• apps that need relayers or sponsored transactions
• protocols using automation and scheduled execution
• consumer apps where gas abstraction matters
• teams that want appchain support plus adjacent Web3 cloud tools
• projects that need developer infrastructure around the chain, not only chain launch

The key diligence point is scope. Buyers should clarify whether Gelato is being considered for RaaS, automation, relay, account abstraction, or a combination. The more product layers involved, the more important it becomes to understand pricing, dependency risk and support responsibility.

Questions to ask Gelato:

• Which appchain stacks and deployment models are supported?
• What automation, relayer and account abstraction tools are included?
• What support exists for monitoring and incident response?
• How does pricing work across chain operations and developer services?
• Which parts of the stack are Gelato-operated versus partner-operated?
• What happens if transaction volumes spike?

Buyer Framework: When to Launch an Appchain

Launch an appchain when:

• the application needs dedicated throughput
• fee predictability matters
• UX depends on custom gas or account rules
• the product needs custom compliance or permissioning
• the ecosystem wants its own app-specific economy
• existing networks create too much congestion or dependency

Do not launch an appchain when:

• the app has no liquidity strategy
• the team has no bridge and onboarding plan
• an existing L2 is sufficient
• the budget cannot support chain operations
• the legal and compliance model is unclear
• the user base does not care about dedicated infrastructure

The Most Important Questions

Before choosing a RaaS provider, answer these questions internally:

• Why do we need our own chain?
• Which assets must move in and out?
• Where does liquidity come from?
• Who operates the sequencer?
• What bridge assumptions are acceptable?
• What is the data availability strategy?
• What happens during downtime?
• Who handles upgrades?
• What tools do developers and users need on day one?

Which Provider Should You Shortlist?

Choose Caldera if rollup interoperability and a connected rollup ecosystem are central to your architecture.

Choose Conduit if you want complete chain operations infrastructure with RPC, indexing and tooling attached.

Choose Gelato if the chain is part of a broader developer infrastructure plan involving automation, relaying and account abstraction.

For most buyers, the right shortlist is not one vendor. It is one RaaS provider plus bridge, security, oracle, RPC, data availability and monitoring diligence.
