EdgeDepth vs Tardis.dev
Compare building on historical market data with using a prepared research engine.
When Tardis.dev fits
Choose Tardis.dev when you need granular multi-exchange data, downloadable datasets and client libraries for your own research or simulation infrastructure.
When EdgeDepth fits
Choose EdgeDepth when your question fits its supported crypto definitions and you want the capture, query engine, outcome summaries and browser evidence workflow together.
What each workflow gives you
| Decision | Tardis.dev | EdgeDepth |
|---|---|---|
| Data | Tick-level order-book snapshots and updates, trades and derivatives datasets across supported exchanges. | Research covers Binance USDT-M; live coverage includes Binance USDT-M, Hyperliquid and Bybit perpetuals. Live analysis and recorded replay sit alongside research; broker order execution is not provided. |
| Replay | APIs and client libraries replay historical market messages and support order-book reconstruction. | Replay recorded trades and order-book updates with heatmaps, footprints and profiles. Seek through the recorded sequence in the browser. Available views depend on recorded streams and plan access. |
| Code access | Python, Node.js, HTTP access and downloadable CSV datasets support custom pipelines. | The terminal is open source and can connect to a compatible data gateway. Hosted research also exposes versioned definitions through REST and MCP; hosted data services are separate from the terminal source. |
| Research ownership | You choose the measurements, sampling, outcomes, execution assumptions and validation code. | Supported definitions, population summaries and evidence inspection are integrated. Custom simulation and strategy validation remain separate work. |
Live order flow, recorded replay and research together
Read resting liquidity on the order-book heatmap, inspect executed volume in footprints, and use TPO, session profiles and VWAP for context. The liquidation layers add a separate view: modeled liquidation pressure is distinct from resting orders and observed liquidation prints.
Those tools support a complete visual investigation inside EdgeDepth. Research adds another step when useful: define a supported condition, count its matches and inspect what followed across the selected record. Open the terminal or test a question.
How it could fit your research
Start with EdgeDepth to investigate a supported question. If the work needs custom measurements, more exchanges or a bespoke fill simulation, a historical-data provider can be the better foundation. Those capabilities require your own study logic and validation.
In EdgeDepth, review the exact setup, markets and dates. Read both favourable and adverse outcomes, check missing windows and inspect counterexamples. A same-scope unconditional reference includes matches and is not a matched control group. An interesting pattern is a reason for another check, not proof of profitability.
Coverage and access matter
Search can reach the full verified research record, with availability varying by measurement and market. Pro tick replay covers 90 days; Research reaches the recorded order book, from 15 May 2026. Research history and replay coverage are different: the record is searchable from 15 July 2025, but days before the book cannot be replayed. Check coverage and current plans for your intended workflow.
EdgeDepth has live order flow, an event archive, lessons and open-source terminal tools alongside research. It does not execute trades. A monitored condition means the setup occurred again, not that an order should be placed.

Common questions
Is Tardis.dev replay the same as a browser study? #
Tardis.dev replay delivers historical market data for software to consume. EdgeDepth tick replay is an interactive evidence view linked to its hosted research workflow. Both involve historical data, but they address different parts of the research process.
Can I inspect EdgeDepth before paying? #
Yes. The hosted live terminal has a free tier, and public demos let you inspect replay. The open-source terminal can run with a compatible gateway. Advanced hosted features, research allowances and replay access vary by plan; existing public reports are free to read.
