## Heimdall

Heimdall organises machine learning around two distinct starting points. The first is the classic data path: you bring CSV files or connect a database, ingest and version them across bronze, silver and gold layers in Lake, explore and profile tables with Python notebooks in Lab, then publish gold tables that the ML and Forecast products train on. ML covers classification and regression, while Forecast produces time-series predictions for demand and capacity planning with explanations you can inspect. Every model finishes as a monitored REST endpoint with usage metering and a health check.

The second path is for teams who have no training data yet. Loop is an online-learning product whose models keep adapting to fresh live feedback rather than a fixed training set, which suits recommendation and ranking style problems. Resolve takes unstructured text and turns it into a category or a score using answers you define yourself — no labelled history required — which makes it useful for routing incoming emails or grading urgency. Both paths still end in the same deployable, monitored API surface.

Because the platform bundles cataloging, notebooks, modelling and deployment, it is a fit for small data teams that want production machine learning without assembling separate warehouse, notebook and MLOps vendors. Access starts with a free account and a self-serve workspace; larger deployments are handled through a conversation with the team, so published prices are not listed publicly.

**Pricing & Plans:** Heimdall offers a free account for creating a workspace and exploring the platform, with documentation available for every product. Paid and enterprise pricing is not published on the site and is handled by contacting the team directly, so cost depends on your data volume, deployment scope and support needs.

- **Medallion data lake:** Ingest structured and unstructured data, organise it into bronze, silver and gold layers, and publish gold tables that downstream models can train on.
- **Lab notebooks:** Profile lake tables with Python, pandas and charts, then save your transforms back into the silver layer without leaving the browser workspace.
- **No-code ML and Forecast:** Train classification and regression models or generate explainable time-series forecasts, each deployed as its own monitored REST API endpoint.
- **Loop online learning:** Start without a dataset and let models keep updating themselves from fresh live signals — useful for ranking, recommendations and adaptive scoring.
- **Resolve text scoring:** Convert unstructured text into a choice or a score using answer definitions you write yourself, with no labelled training history required.

**Strengths:** Two clear entry paths, so you can start with data or with no dataset at all; Every path ends in a monitored REST API with usage tracking and a health check; Lake, Lab, ML and Forecast live in one workspace rather than separate vendors; Free account and full product documentation lower the cost of evaluating the platform

**Limitations:** No public price list, so budgeting requires contacting the team; The data-dependent products still require you to prepare and publish gold tables before training; It is a developer-flavoured platform with REST APIs and workspaces rather than a polished business-user app

## Hex

Hex starts from a simple observation: dashboards tell you what happened, but they rarely answer the follow-up question. Its core is the Hex Agent, a conversational interface that plans a query, reasons over your organisation's context and returns an answer with the charts, tables and code that produced it. Because every answer is grounded in a semantic model and the underlying warehouse tables, users can inspect the SQL, check assumptions and trust the number before acting on it. The agent is reachable from the web workspace, from Slack, and from developer tools such as Claude and Codex via CLI and integrations.
Underneath the conversational layer sits a genuine notebook and app-building environment. Analysts write SQL, Python and R in the same project, chain cells into reproducible pipelines, and then turn selected cells into polished, parameterised data apps and dashboards that stakeholders can interact with. Hex 4.0 pushes this further with generative dashboards, AI app building and a Context Engine that keeps the company's definitions, metrics and semantics in one place. A Context Studio surfaces where the agent lacked grounding, and an Evals framework lets teams run graded test suites against the agent to measure accuracy over time.
That governance angle is what separates Hex from raw chat-with-your-data tools. Instead of an unsearchable answer in a side panel, you get a shareable, versionable artefact with lineage, plus a feedback loop that compounds context quality. It is used by data teams at a wide range of companies for self-serve exploration, executive reporting, embedded dashboards and operational analytics, with free, paid and enterprise tiers covering individuals through to regulated organisations needing SSO and advanced security.

**Pricing & Plans:** Freemium with a free tier to get started, paid plans for growing teams, and enterprise pricing (quoted on request) that adds governance, SSO and advanced security. A free trial is available for paid tiers.

- **Conversational Hex Agent:** Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
- **Notebooks and app builder:** Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
- **Context Engine and Context Studio:** Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
- **Evals for agent accuracy:** Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
- **Generative dashboards and governance:** Produce dashboards from natural language, embed them where teams work, and manage access with enterprise-grade permissions and security.

**Strengths:** Unifies exploration, notebooks, dashboards and app building so teams stop paying for four overlapping tools; Answers are grounded in a semantic model and warehouse tables, and stay inspectable rather than opaque; Slack, CLI and developer-tool integrations meet users where they already work; Context Studio and Evals turn context quality into something measurable and improvable

**Limitations:** The full value depends on having a reasonably well-modelled warehouse, so it is heavier to adopt than a simple chat tool; The notebook-plus-agent surface is feature-rich enough to need onboarding for non-technical users; Governance and advanced security features are reserved for higher-priced and enterprise plans
