The data of the currently operating gamma-ray telescopes is mostly analysed with an increasingly diverse set of instrument-specific analysis tools. The instrument independent framework GammaLib is currently developed for the analysis of the high-level data products of the upcoming Cherenkov Telescope Array (CTA). It will be provided as open source software for any kind of gamma-ray data from existing telescopes. Based on GammaLib, a set of analysis executables were created (ctools). These powerful tools provide the opportunity of simultaneous multi-instrument analyses which will be in particular helpful during the HESS upgrade. The ctools software also provides support for studying extended gamma-ray sources. To test the ctools framework on HESS data, we made cross-checks on well-established sources like the Crab Nebula or the Galactic center with good agreements of the results from the HESS internal analysis framework and the ctools framework. An overview of the instrument performance and future plans will be given.
