Specify
Define users, constraints, stack, and a machine-checkable definition of done.

One clear specification enters. Independent build lanes compete. Tests, security, and quality gates choose what earns the right to ship.
A transparent software production line,
built for developers who measure the result.
Generation is only the beginning. Hephaestion carries a build through requirements, architecture, implementation, tests, security, documentation, and release review—then preserves the evidence. Live API and competitive lanes run at hephaestion.echo-op.com.
Sanitized proof-of-work packages live on the platform origin. Download the Hephaestion sample before you spend a credit — full gate evidence, no customer PII.
Inspect the sanitized proof-of-work package before you buy — full evidence chain, no customer PII. Hosted at the platform origin so every forge page shares one download.
The forge makes every consequential decision observable. You see the stage, the lane, the score, and the gate—not a progress animation hiding a single opaque call.
Define users, constraints, stack, and a machine-checkable definition of done.
Independent build lanes attack the same contract. The strongest candidate advances.
Tests, security, quality, and final review can stop the line. Findings stay visible.
Export source, documentation, deployment config, reports, and the build receipt.
Every lane rises on measured Hephaestion outcomes: gate scores, wins, and production-grade submissions.
Data read directly from the Hephaestion production leaderboard. No sample scores.
Credits make pipeline cost legible: deeper competition, more review rounds, and stricter gates consume more. Every grade preserves the build evidence.
For individual builders proving a real product direction.
For serious teams shipping customer-facing software.
For controlled environments, private models, and team governance.
Choose a forge grade, apply a promo code if you have one, then start a build. Credits are estimated before CONFIRM — nothing is charged without your acknowledgment.
Checkout continues on the live build floor after sign-in. Platform billing and Full Foundry bundle live at the Echo Forge pricing surface.
Map build work types to estimated forge credits — Small FastAPI set (250–500), Competitive 3-lane SaaS (3,000–6,000), and more. The build form shows the same range and requires CONFIRM before execution.
This run will consume ~250–500 credits
Single service or small API surface: routes, models, tests, baseline security gate, source export.
| Forge | Work type | Estimated credits |
|---|---|---|
| Hephaestion | Small FastAPI setSingle service or small API surface: routes, models, tests, baseline security gate, source export. | 250–500 |
| Hephaestion | CRUD web appAuthenticated CRUD product with migrations, UI shell, acceptance tests, and quality gate. | 800–1,600 |
| Hephaestion | Competitive 3-lane SaaSFull SaaS contract with three independent build lanes competing through 13 stages and 4 fail-closed gates. | 3,000–6,000 |
| Hephaestion | Enterprise integration packMulti-service integration, custom gates, compliance artifacts, and committed-capacity handoff. | 5,000–12,000 |
How credits expire, roll over, overage is priced, failed runs are treated, and what happens to exports after cancel.
| Topic | Summary | Detail |
|---|---|---|
| Credit expiration | Monthly allotments expire at the end of each billing period. | Subscription credits are granted at period start and expire when the period ends. Unused credits do not convert to cash. One-time top-up packs (when offered) expire 90 days after purchase unless the pack states otherwise. |
| Rollover | Up to 20% of unused monthly credits roll over once. | At most 20% of the period’s unused allotment may roll into the next billing period, and rolled credits expire at the end of that next period (no multi-month stacking). Enterprise committed-capacity plans may define custom rollover in the order form. |
| Overage price | $0.05 per credit after the monthly allotment is exhausted. | When a confirmed run would exceed remaining credits, we show the projected overage before you confirm. Overage is billed at $0.05 USD per credit (or the rate on your enterprise order form). You can decline overage and cancel the run with no charge. |
| Failed builds & retries | Platform faults are not charged; customer retries charge only after confirm. | If a run fails because of a platform or infrastructure fault (our side), consumed credits for that run are refunded to the period balance. Customer-initiated retries, re-specs, and re-runs after a fail-closed gate require a new estimate and a new CONFIRM; they consume credits only after you confirm. |
| Cancellation & export | Cancel anytime; finished work stays exportable for 90 days. | You may cancel a forge or Full Foundry subscription anytime; access continues through the paid period. Completed artifacts, reports, and seals remain available for export for 90 days after the subscription ends. Incomplete in-flight runs are stopped at period end; partial work that has not passed gates is not guaranteed exportable. See Refunds & Cancellation for billing refunds. |
Hephaestion Production + Daedalus Workshop + Certification seat — one account, one bill, shared priority queue.
Save $149/mo vs Production + Workshop bought separately ($299 + $449).
Describe the software, see This run will consume ~X–Y credits, then CONFIRM before any forge credits are consumed.
Credits are consumed by pipeline work, not seats. Usage estimates appear before a build begins. Enterprise terms are scoped to infrastructure and policy requirements. Live competitive lanes: hephaestion.echo-op.com.
