## Raindrop

Agents fail differently from normal software. A run can complete without any exception while still producing the wrong answer, calling the wrong tool, or looping on a failed retry. Raindrop is designed around that reality: it records each message, tool call and decision as a trace, then looks for patterns across many runs so a recurring problem becomes a single, trackable issue with severity, affected user counts and confidence.

The workflow moves from signal to fix. Teams trace an individual run to see exactly where things went wrong, use the triage agent to investigate and automate work in Slack, the web app or via MCP, and then run simulations on a pull request to see what a change would do before merging. A comparison view checks the change against real traffic so you can confirm which behaviours improved rather than guessing. A local Workshop tool lets engineers inspect, replay and debug agents on their own machines.

Raindrop covers both monitoring and pre-release testing, which makes it useful for teams shipping agents to large audiences — the site notes customers running agents used by millions of users. Because the space moves quickly, feature names and packaging may change; check the site and docs for the current scope, and note that the company has raised a $50m Series A, a signal of continued investment.

**Pricing & Plans:** Raindrop offers a free starting tier with no credit card required for individual developers and small teams, plus paid plans for larger usage, an enterprise option, and a free programme for teams building agents for social good. Exact seat and usage pricing is on the pricing page and can change, so confirm there before committing.

- **Agent tracing:** See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
- **Automatic issue detection:** Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
- **Triage agent and integrations:** An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
- **Simulations in CI:** Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.
- **Local Workshop debugger:** Inspect, replay and debug agent behaviour locally without round-tripping through production.

**Strengths:** Purpose-built for agent traces and non-throwing failures, not generic APM; Covers the full loop from detection to investigation to simulation; Triage agent works inside Slack, web and MCP where teams already operate; Free starting tier and no credit card required to begin

**Limitations:** Aimed at teams already running agents in production, which is a narrowing audience; Advanced simulation and enterprise capabilities sit behind paid and enterprise plans; Fast-moving product surface means some features may shift or be labelled beta

## Sim AI

Sim is an open-source AI workspace for companies that need to build, distribute and govern AI agents rather than run isolated prompts. It brings four connected products into one environment: Workflows for designing repeatable agent logic, Knowledge Base for grounding agents in internal documents, Tables for structured data agents can read and update, and Files for shared inputs, outputs and artifacts. A Logs product traces every run for debugging and cost visibility.
Teams can build through conversation in Chat, by arranging blocks on a visual canvas, or by writing code and using the CLI. Integration coverage is broad, with 270+ connectors spanning Slack, GitHub, Gmail, Notion, Salesforce, Jira, Linear, Supabase and Stripe, alongside every major LLM including OpenAI, Anthropic, Google, DeepSeek and xAI models. The Knowledge Base automatically syncs sources such as Notion, Google Drive, Confluence, Slack, GitHub and SharePoint, so agents answer from current content instead of stale snapshots.
Governance is the other half of the product. Administrators set permission groups for models, integrations and tools, define organization and per-member spend limits, retain audit records, and configure workspace data retention. Sim Cloud is available alongside self-hosting via Docker or Kubernetes under the Apache 2.0 license, with enterprise features gated by a license. The company publishes a Trust Center covering SOC 2 Type II, ISO 27001 and GDPR, and counts Rivian and eXp Realty as customers.

**Pricing & Plans:** Free forever on Sim Cloud with 1,000 one-time credits, 1 workspace and 5 GB storage. Pro is $25 per user/month (6,000 credits/month), Max is $100 per user/month (25,000 credits/month), and Enterprise is custom. Sim Cloud credits are worth $0.005 each, and the platform is free to self-host under Apache 2.0.

- **Build agents three ways:** Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
- **Knowledge Base with live sync:** Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
- **Tables and Files:** Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
- **Execution logs and cost tracking:** Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
- **Enterprise governance and self-hosting:** Manage SSO and SCIM provisioning, permission groups, model and tool access, spend limits, data retention and Docker or Kubernetes deployment.

**Strengths:** Open source under Apache 2.0 with free Docker and Kubernetes self-hosting; Four plans from Free to Enterprise, so teams can start without a sales call; 270+ integrations and every major LLM in one workspace; Knowledge Base auto-syncs from Notion, Drive, Confluence, Slack, GitHub and SharePoint

**Limitations:** Credit-based Cloud pricing can be harder to forecast than flat seat pricing; Enterprise governance features such as SSO, SOC 2 controls and self-hosted enterprise licensing sit above the Free plan; With 270+ integrations and four plan tiers, first-time setup requires deliberate configuration; Small Free plan limits (1 workspace, 5 GB storage, 30-day log retention) push team use toward paid tiers
