# Alternatives to Sierra > Source: https://theagentsindex.com/sierra/alternatives (current datasheets, evidence-ranked) Candidates share the baseline category or are previously researched peers. Requirements, preserved strengths, explicit trade-offs and research coverage decide the order; paid tier does not. ## Shortlist ### 1. LangChain Open source agent frameworks plus LangSmith, a hosted platform to trace, evaluate, deploy and govern agents. **Research coverage:** 34/35 criteria **Where it improves on Sierra:** - [Writes code: yes — The vendor ships dcode, a free open-source terminal coding agent that writes and runs code from a prompt; it is a separate package from the paid LangSmith platform.](https://www.langchain.com/dcode) - [Ships it: yes — LangSmith Deployment runs agents in production with one-click deploy from Studio and a control-plane API; the free Developer plan shows Deployment as N/A, so shipping starts at Plus.](https://docs.langchain.com/langsmith/studio) - [Multi-agent: yes — LangGraph is built for coordinating several agents in one graph, including hierarchical supervisors, and dcode delegates work to task-specific subagents in parallel.](https://www.langchain.com/langgraph) **Trade-offs against Sierra:** - No researched regression against the baseline.

Salesforce Agentforce Salesforce's platform for building, deploying and monitoring AI agents on top of CRM data. **Research coverage:** 35/35 criteria **Where it improves on Sierra:** - [Writes code: yes — The Agentforce Vibes coding agent turns a natural-language description into Salesforce code and metadata.](https://www.salesforce.com/agentforce/developers/vibe-coding/) - [Debugs and fixes: yes — Vibes runs the test or deployment, reads the failure and iterates toward a fix rather than stopping at the error.](https://developer.salesforce.com/docs/platform/agentforcevibes/guide/afv-agentic-dev.html) - [Writes tests: yes — Apex test classes and LWC Jest tests are generated alongside the code, with a dedicated QA Validator sub-agent for coverage.](https://developer.salesforce.com/docs/platform/agentforcevibes/guide/afv-agentic-dev.html) **Trade-offs against Sierra:** - [Agent permissions: partial — Guardrails and filters bound which topics and actions an agent may reach and data access honours existing Salesforce permissions, but an approval-before-every-action mode is documented only for the Agentforce Vibes coding agent.](https://www.salesforce.com/agentforce/how-it-works/) [View Salesforce Agentforce](https://theagentsindex.com/salesforce-agentforce) ### 3. MindStudio No-code platform for building, running and deploying AI agents as drag-and-drop workflows. **Research coverage:** 35/35 criteria **Where it improves on Sierra:** - [Ships it: yes — Publishing and deploying agents is unlimited on both paid tiers; deployment targets include hosted web apps, website embeds, webhooks, scheduled runs and, on Business, custom domains.](https://www.mindstudio.ai/pricing) - [Multi-agent: yes — A workflow can spawn one or more child workflows, and packaged agents can be called as blocks inside another agent, giving multi-agent orchestration inside one run.](https://www.mindstudio.ai/capabilities) - [Claude: yes — Anthropic is a first-class publisher in the model catalogue with fifteen Claude entries listed alongside their per-million-token input and output rates.](https://www.mindstudio.ai/pricing) **Trade-offs against Sierra:** - [Agent permissions: partial — Approval is something the builder designs in with a checkpoint block rather than a platform-wide permission model, so how much an agent does unattended depends on the workflow author.](https://www.mindstudio.ai/capabilities) - [Admin controls: partial — Restricting which models and third-party services a workspace may reach, and controlling access per user, are ticked only in the Business column and crossed for Individual.](https://www.mindstudio.ai/pricing) [View MindStudio](https://theagentsindex.com/mindstudio) ### 4. Ada Enterprise AI customer service agents across voice, messaging and email, with tool use in your own systems. **Research coverage:** 35/35 criteria **Where it improves on Sierra:** - [Open source: partial — Only the client-side chat UI library is distributed publicly on npm as @ada-cx/lovelace; the platform and Reasoning Engine are hosted with no published source.](https://docs.ada.cx/lovelace/overview) - [MCP server: yes — Ada runs its own MCP server over Streamable HTTP with OAuth or API-key auth, exposing most dashboard operations to any MCP client; it also consumes MCP servers you run as agent tools.](https://docs.ada.cx/mcp/introduction/overview) - [Seat model: partial — Dashboard access is per named user with four roles, invited and removed per Ada instance, but no seat price, seat minimum or seat ceiling is published anywhere, so the commercial half of the seat model is unknown.](https://docs.ada.cx/docs/other/team-access/my-team) **Trade-offs against Sierra:** - [Debugs and fixes: no — Ada diagnoses its own agent's conversations, not software failures; its only code surface is a small data-shaping Python tool.](https://docs.ada.cx/docs/automation/tools/code-tools) - [Writes tests: no — Test cases here are multi-turn conversation scenarios scored pass/fail against the AI agent's replies, not software tests.](https://docs.ada.cx/mcp/introduction/overview) [View Ada](https://theagentsindex.com/ada) ### 5. ElevenLabs Agents Hosted platform for building voice and chat agents, with telephony, SDKs and a choice of LLM. **Research coverage:** 35/35 criteria **Where it improves on Sierra:** - [Multi-agent: yes — An orchestrator agent routes a live conversation to specialist agents on natural-language conditions, and transfers can be nested; the transcript carries across.](https://elevenlabs.io/docs/eleven-agents/customization/tools/system-tools/agent-transfer) - [Claude: yes — Anthropic models are natively selectable in agent settings; a few older Claude models drop out in EU data-residency workspaces.](https://elevenlabs.io/docs/eleven-agents/customization/llm) - [GPT: yes — OpenAI models are natively supported and are the one provider family the vendor says stays fully available under EU data residency.](https://elevenlabs.io/docs/eleven-agents/customization/llm) **Trade-offs against Sierra:** - [In your editor: no — The vendor enumerates its surfaces as web widgets, mobile apps, phone systems and custom integrations; no editor or IDE extension appears in that list.](https://elevenlabs.io/docs/eleven-agents/integrate/overview) - [Admin controls: partial — Guardrails constrain what an agent may say and per-tool approval constrains what it may do, but Guardrails is in Alpha and enabling MCP servers is not restricted to admins.](https://elevenlabs.io/docs/eleven-agents/best-practices/guardrails) [View ElevenLabs Agents](https://theagentsindex.com/elevenlabs-conversational-ai) ### 6. UiPath Agent Builder Low-code canvas in UiPath Studio Web for building AI agents that run on the UiPath automation platform. **Research coverage:** 35/35 criteria **Where it improves on Sierra:** - [Ships it: yes — It does not stop at a design: the agent is published and deployed as an Orchestrator process, the CLI provisions a serverless machine and robot user for it, and Orchestrator then schedules and monitors the runs.](https://www.uipath.com/platform/agentic-automation/agentic-ai/agent-builder) - [Multi-agent: yes — Two separate mechanisms: an agent can add another published agent as a tool and chain capabilities, and Maestro coordinates several agents, robots and people across one BPMN process.](https://docs.uipath.com/agents/automation-cloud/latest/user-guide/tools-agents) - [Claude: yes — Anthropic is one of only three model providers the Agents documentation lists as selectable for an agent, served through AWS Bedrock, and you choose it per agent in the Properties panel.](https://docs.uipath.com/agents/automation-cloud/latest/user-guide/analyze-files) **Trade-offs against Sierra:** - [Done-for-you service: no — This is licensed software the customer operates, pitched explicitly at the business user building the agent themselves; UiPath sells no build-and-run service on this page, only a trial and a demo.](https://www.uipath.com/platform/agentic-automation/agentic-ai/agent-builder) - [Admin controls: partial — Admins get Automation Ops governance policies that can override an agent's model settings, plus custom roles and access policies, but both rows carry an em dash on the Basic tier and start at Standard.](https://www.uipath.com/pricing) [View UiPath Agent Builder](https://theagentsindex.com/uipath-agent-builder) ## Method Unknown data is never treated as a benefit or a trade-off.
