Agentic development delivers speed. Experience delivers software that survives production.
We deliver both — spec-driven, accountable, since 1997.
Aberger Software combines engineering discipline since 1997 with modern agentic development. Speed without control is worthless — we keep both.
Agentic, but not arbitrary
We use Claude Code, Codex, Google Stitch, Antigravity and OpenCode as engineering amplifiers.
These tools do not replace software competence. They are guided by clear specifications, reviews, tests and architecture decisions. The result is not vibe coding, but traceable and maintainable software.
Quality is the highest value
Maintainability, operations and traceability decide how long a system lives.
We bring experience from domain modelling, business-critical systems and long production operation into agentic programming — the best of both worlds.
Spec-driven development: requirements, architecture, implementation and verification are described explicitly before code is written. With OpenSpec, the specification is the shared reference point for humans and coding agents.
-
Specification
Behaviour, constraints, data model and acceptance criteria are captured explicitly with OpenSpec.
-
Implementation
Coding agents implement the specification — guided by architecture decisions and reviews.
-
Verification
Tests, type checking and reviews check the change against the specification.
-
Feedback
Findings flow back into the specification — the loop restarts until the change is robust in substance and in code.
OpenSpec structures proposal, design, specification and tasks so every change stays reviewable:
### Requirement: Anchored experience claims
Marketing pages SHALL anchor experience claims to the founding year 1997.
#### Scenario: Founding year present
- WHEN the homepage is rendered
- THEN "1997" appears in the proof content
We enable teams to adopt spec-driven agentic development productively — with control instead of vibe coding.
Consulting and training
We guide your team in adopting spec-driven development with OpenSpec and coding agents.
From tool selection through specification and review practices to robust agent workflows: we pass on engineering experience gathered since 1997, so speed and software quality come together.

Agentic Programming Principles
Explicit Native Systems: why readable, native systems collaborate better with humans and LLMs.
Our principles for agentic development favour native browser and Java primitives over hidden framework layers. That keeps systems understandable, verifiable and ready to hand over.
